Feel free to browse the answers to frequently asked questions and the information pages and if you want find the answers to say ‘How Do I fit a pump in the loft (or under the bath), and you cannot see the topic below, simply use the search box on this site to find what you want.

(1) Pump Selection

The Shower Power Booster is suitable for mains pressure system and gravity systems.

For gravity systems 80% of people will get a great shower with just one SPB on the hot – a pump on the hot and cold is better. A manual pump gives the same boost as an automatic but most people prefer fully automatic.

Based on our experience of what customers need our guides tell you what we think you need. If you try one pump then decide you want to double boost or want balanced flow you can always buy one pump and return to us to buy a cheap upgrade pump at any time after your first purchase.

Our Simplified Pump Selection Guide will lead you to the solution you need

(2) Can I boost every tap and shower in the whole house with a single pump

A single ShowerPowerBooster fitted near the hot water cylinder could boost every tap and shower in the house and this is the first choice for most customers.Is this the right choice for me?

A pair of shower power boosters fitted on the hot and cold to a shower stops the shower fluctuating in temperature when someone else turns a tap on.

It will depend on your own home and your needs.You could go for either according to what is important to you or you might even decide to boost every tap and shower and protect the flow to your shower at the same time (a double boost on the hot and a single boost on the cold).

Visit our information page to see what options are available – boosting the whole house or just a single tap or shower?

If you have an upstairs shower or a bungalow with a cold tank in the loft, a single micropump will add around 3 metres head, which added to the 1 metre head you already have gives:

Quadruple your pressure and double your flow!

In all cases where we double the pressure your flow will increase by 50% (A downstairs shower with 3 metres head already will only double in pressure with a 25% increase in flow).

Boost the power and flow of your tap or shower!

4 out of 5 people get away with just a single pump on the hot as most people like hot showers requiring 2/3 hot to 1/3 cold, there is normally enough cold pressure to achieve this. For people who like cold showers, or your cold pressure is very poor (or your mixer needs a balanced flow), a second pump on the cold may be required. We sell a second pump at half the cost of the hot pump, if you are unlucky enough to need this.

(2) Mains Pressure Cold & Boosted Gravity Hot


If you have mains water cold it can often unbalance a mixer tap or shower so reducing that imbalance with a shower power booster means that the effect of boosting the hot side of a mixer will not only give you and increase in hot water pressure but the mixer will allow more hot water to pass.

We have a more detailed explanation of why just a pump on the hot works so well in our information pages.

(3) Boosting Electric Showers

Shower Power Booster Range

A shower power booster is ideal for electric showers which are shutting down because the mains pressure is too low or the pressure fluctuates someone in your house or your neighbour turns a tap on. Just boost the cold feed to an electric shower.

A shower power booster will always sort out a pressure problem with an electric shower but only if the problem is pressure related. An electric shower can never deliver hot water at a rate faster than an electric shower can heat it.

Fitting a shower power booster can be simplicity itself, remove 115mm of pipe, insert the pump, tighten the compression joints, plug it in, enjoy. You can fit a shower power booster in any position so you can fit it away from the electric shower out of sight.For most people a single pump is ok but if after fitting one pump you can always add a second so so double boost.

Connecting a Shower Power Booster To The Mains
Connecting a shower power booster to a mains supply is very easy and this can be a major advantage over our competitors. Click the link below to see how.

Connecting a Shower Power Booster To The Mains.

If you have a combi boiler and an electric shower you can boost both by putting the SPB on the incoming mains feed which serves both.

Will a Shower Power Booster Work or Do I Need a New Electric Shower
The maximum output of an electric shower is determined by its KW power rating and in winter because the cold water is colder then the output is less:-

7.5 KW Electric Shower 3.5 litres a minute
9.8 KW Electric Shower 4.7 litres a minute
12.5 KW Electric Shower 6.0 litres a minute

If by turning the shower to cold you get more water to flow then its probably because the electric shower itself is turning down the water pressure. Simply adding pressure will cause the electric shower to reduce the pressure further to what you had before you fitted the pump.

If you do not get an increase in flow turning the shower from hot to cold, or especially if the shower is cutting out due to low pressure, then the Shower Power Booster can be a perfect solution. 15 minutes – job done – much better shower – and you have joined hundreds of other happy customers.

There are 2 features to an electric shower which important:-

AT LOW PRESSURE AN ELECTRIC SHOWER TURNS OFF
If the pressure drops below 1 bar (1 bar = 10 metres head), a switch turns the shower heater off. This is very easily solved with a shower power booster on the cold feed to the shower. A single Shower Power Booster on the mains feed will add up to 5 metres head to any electric shower and this can stop the shower cutting out as your mains pressure falls and will also give you a better showering experience every time you use the shower.

If for instance you only have 0.8 bars pressure and your electric shower stops working, the shower power booster adds 0.4 bars so your shower has 20% more pressure than it needs to work – it works!If a single shower power booster does not solve your problem then a second shower power boosters in series will double the pressure and will sort it!!!!

The invention allows us to set a maximum flow so we comply with the legal requirement not to exceed 12 litres a minute for a pump fitted to a mains supply. If a single pump does not work because your pressure is very low just add a second shower power booster to double the added pressure.

AN ELECTRIC SHOWER REDUCES THE FLOW AND PRESSURE ACCORDING TO HOW COLD THE COLD WATER SUPPLY IS
If you turn an electric shower from hot to cold and the pressure and flow increases there is every chance that the electric shower itself is limiting the flow and pressure.For such showers it is the not water pressure which is limiting the flow but the size of the electric shower. A shower power booster will increase the pressure for such showers but the electric shower itself stops the increased pressure reaching the shower head.

The only way you can improve the flow might be to buy an electric shower with a greater KW rating. If you shower is reaching the end of its working life or you might want to opt for a refreshing boosted gravity shower. If you have a gas or oil boiler, a boosted gravity shower will give an excellent shower and a family of 4 could save £125 a year in energy costs.

Electric showers are designed to run from the mains because extra pressure is required to drive fine spray through small water jets rather than the larger jets of traditional gravity showers. This is because an electric shower flow is limited to the amount of water it can heat (as said earlier), so in order to give the impression of a good shower, with a small amount of water, it needs greater pressures, and a finer spray hose. A typical electric shower will give you 3.5 litres a minute which is adequate for some provided there is enough pressure.

CONSIDER CHANGING TO A GRAVITY BOOSTED SHOWER
Electricity is a very expensive way to heat water so boosting your gravity shower with a shower power booster to boost your pressure can save lots of money if you have a gas boiler. For a family of 4 having 5 minute showers, switching from electric showers to gravity boosted showers then the change can pay for itself in under a year. Every home is different and some teenagers are in the shower for more than 5 minutes!!!

For those who like to see the calculations then they are as follows (cost per year for a family of 4):-

COST OF SHOWERS USING ELECTRICITY – £229.34
Water used for a 6 litre a minute shower for 5 minutes = 30 litres.
Cost of water is 30 litres at 0.1p a litre = 3p.
4 person household at 1 shower a day 365 days a year = 4x365x3p = £43.80.
For each shower:- Cost of electricity 12.2p per KW/HR so 12.5KW x 12.2p x (5/60) = 12.7p
4 person household at 1 shower a day 360 days a year = 4x360x12.7p = £185.54
TOTAL £229.34

COST OF SHOWRS USING A GRAVITY SHOWER BOOSTED WITH SHOWERPOWERBOOSTER
Water used for a 6 litre a minute shower for 5 minutes = 30 litres.
Cost of water is 30 litres at 0.1p a litre = 3p.
4 person household at 1 shower a day 365 days a year = 4x360x3p = £43.80.
For each shower:- Cost of gas 3.89p per KW/HR so 12.5KW x 3.89 x (5/60) = 4.1p
4 person household at 1 shower a day 360 days a year = 4x365x4.1p = £59.86
TOTAL £103.66

SAVING £125.68 per year

(5) Boosting a Single Tap or Shower

A single ShowerPowerBooster fitted on the hot feed to a shower will maintain a good shower even if someone opens other hot taps in a home.

If all of your taps and showers except one appear ok it is an option to boost just the shower that needs more power. This is also the case if the shower is fed off the vent pipe in the loft.

If you live in a home with multiple occupants, all wanting to shower or run taps at the same time, then it is possible also possible to protect and boost every shower and tap at the same time using multiple shower boosters. The advantage of this is that people can continue to shower with the fear that the shower is about to die or go cold when others turn on taps.

With multiple showers it is easy to use more water than your system can cope with the ShowerPowerBooster will achieve a great shower with only half the water of a power shower and no one shower will steal the lot.Water will always take the path of least resistance.

If you offer the choice to water to flow from a tap or shower it will always favour the tap.

If you offer the choice to water to flow into a suction inlet of a pump or a tap it will always favour the pump.

Put a shower power booster upstream of a shower and the pump will reprioritise the flow of water and the SPB makes sending water to your shower top priority.

This makes our pumps unique in being the only pumps recommended and able to be fitted on the hot side of a Combi Boiler, Megaflow, or indeed any system.

Fully protect your shower with a pump on the hot and cold feed to a shower mixer and protect the shower.

(6) What pump do I need? I have Gravity Hot & Cold

Gravity Hot & Cold

A Single Shower Power Booster is sufficient for most installations, pressuring the hot side.

A good mixer tap will balance hot & cold with a pressure differential of 4 to 1.

However, if your hot & cold supplies are both very low pressure (or your mixer is very poor at balancing pressures) we would recommend a pump on both the hot and cold (SP22S).

Recommended Pumps

SP22S An Automatic Pump on the Hot & Cold will boost the whole system and keep the system balanced

SP2B A Single Automatic pump will normally deliver enough pressure

SP1 A Manual pump is suitable for all systems

 

 

 

 

 

(7) What pump do I need? I have Gravity Hot & Mains Fed Cold

Gravity Hot & Mains Fed Cold

A Single Shower Power Booster is sufficient for most installations, pressuring the hot side.

A good mixer tap will balance hot & cold with a pressure differential of 4 to 1.

However, in some homes the mains pressure can be very high, compared to the gravity hot, meaning one pump will not give enough of an increase.

You can either reduced the mains pressure with a PRV or add a second pump to double boost.

Recommended Pumps

SP21S A Manual & Automatic pump on the gravity side will give a double boost

SP2B A Single Automatic pump will normally deliver enough pressure

SP1 A Manual pump is suitable for all systems

 

 

 

 

 

(8) What pump do I need? I have an Electric Shower

Electric Showers

A Single Shower Power Booster will increase the pressure and flow to stop an electric shower from switching off the heating element.

Adding around 0.5 Bar of pressure to the electric shower, a single SPB is often enough for the Electric Shower to work.

If your pressure is exceptionally low then a double boost may be required.

Please note the output of any electric shower is limited by the KW rating. Meaning no matter how many pumps or how much water you supply to the unit it will only heat a specific amount of water:

7.5 KW 3.5 Litres a minute
9.8 KW 4.7 Litres a minute
12.5 KW 6.0 Litres a minute

Recommended Pumps

SP2B A Single Automatic pump will normally deliver enough pressure

SP21S A Manual & Automatic pump will give a double boost

 

 

 

 

 

(9) What pump do I need? I have a Combi Boiler / Megaflow

Combi Boiler / Megaflow

 

 

 

 

 

Like electric showers, Combi Boilers & Megaflows are fitted with a pressure sensor and if the pressure falls below 1 Bar it shuts down.

A single Shower Power Booster on the incoming cold feed will only add around 0.5 Bar of pressure.

We would therefore recommend two pumps which will add between 0.8 – 1 bar pressure.

This should be enough of an increase to keep the Combi Boiler / Megaflow operating.

Recommended Pumps

SP21S A Manual & Automatic pump will give a double boost

SP2B A Single Automatic pump will normally deliver enough pressure

 

 

 

 

 

(10) Can the pumps boost a Low Water Mains Pressure?

The ShowerPowerBooster can legally Boost low water mains pressure in the UK and Scotland.
It is legal to fit a ShowerPowerBooster on the cold mains feed – Click here to see an extract from the Regulations

The ShowerPowerBooster supplies the perfect flow for a single shower or tap flow and you will be able to get this water 24/7 everyday of the week provided there is water in the main.

Shower Power Booster Maximum Flow Rate = 9 Litres per Minute

It is illegal in the UK to take too much water, this would also pose a serious risk to your health and the health of your neighbours.

Even if you wanted a big pump to take enough water to run 3 taps at a time please don’t do it as it not only stirs up the mains but collapses the pressure so you neighbours cannot have water and when they do get water it will probably be contaminated.

Since the ShowerPowerBooster limits flow rather than pressure your best choice for boosting mains water pressure into a home is to double boost and use a SP21S so you get maximum pressure without exceeding the 12 litres a minute maximum. The ShowerPowerBooster will work anywhere in the world as it is powered by a transformer which runs from a 110 to 240 ac power supply which converts it to 12 volts, or runs directly from a 12 volt car battery. Outside the UK we recommend you buy 22mm to 3/4 inch adaptors so you can easily connect to existing local pipework.

The reason for limiting the amount of water you can ‘pull’ from a water distribution main is that a large pump with large suction can cause depressurisation of the incoming pipe which will allow contamination, sewage, and other nasties into the pipe and stir up sediment. In England, Northern Ireland, Wales, and Scotland, the original ‘Water Bylaws’ (now the ‘Water Regulations Guide’), set a limit of 12 litres a minute as the maximum rating of a pump to avoid risk of de-pressurisation.

 

(11) Can I check my pump before installation?

Yes, we recommend that you carry out the following pre fitting checks:

Plug in the transformer and pumps before fitting, and simply blow through the pump to activate the flow switch (automatic pump only). This was done at the factory, so you should not find a problem, but for peace of mind a pre fitting check is recommended.

For further checks go to YouTube and type ‘Shower Power Booster – Pre Fitting Checks’ or Follow the Link.

The LED light on an SP2B (Automatic Pump) is a useful diagnostic tool:

No LED light – Pump has no power
Constant LED light – Flow switch has power
Slow flashing light – Transformer fault
Fast flashing light – Pump is pumping and water flowing through the pump at a rate greater than 1.5 litres a minute

Please note that after switching off the flow switch will delay switching the pump on again for up to 20 seconds (depending on switching program). This delay is deliberate and allows pumps to deal with air entrained in a system and is not a fault.

(12) How do I install the pump?

SPB Pumps can be fitted in most places enabling you to place them where it is easiest to get them. They can be installed at any angle or orientation.

When installing on horizontal pipe please ensure the white motor and blue LED are hanging below the feed. Make sure that the arrow on the body of the pump is in the same direction as the water flow.

See image below for installation details:

SPB-Pipe-installation1

Pumps are designed to fit existing 22mm pipe. We supply 22mm x 15mm 3 piece reducing sets to install the pump on 15mm pipe.

How to use a 3 Piece Reducing Set:

SPB-Pipe-installation2

For other pipes or tricky installations, you can purchase:

  • ¾ Olives
  • 22mm x ¾ Conversion Slip Joints
  • 15mm Slip Couplings
  • 22mm Slip Couplings
  • Copper Inserts

Please note Inserts must be used when using PEX (Plastic) pipe

Pumps are lightweight & compact meaning they can be installed unsupported on existing pipework. They can be installed under the bath, in an airing cupboard, under floorboards and (as they are so quiet) even in a bedroom.

To install, simply remove 115mm of straight pipe, insert the pump & tighten the compression joints.

During installation:

DO NOT hold the white barrel when installing
DO NOT adjust the motor nuts, these are factory set
DO NOT use PTFE Tape
If at all, use jointing compound very sparingly, this can block the filter

See FAQs below for more information regarding where to install pumps.

(13) How do I use the 3 Piece Reducing Set?

Pumps can be installed on either 22mm or 15mm pipe. The body of the pump is 22mm but if you are installing on 15mm pipe we supply 22 x 15mm 3 piece reducing sets to enable installation on 15mm pipe.

First Choice for most customers:
SP2B Automatic pump – Single Boost a Whole House Solution

For a Whole House Solution fit the pump next to the hot water cylinder, after the vent pipe: this will boost every tap & shower in the house.

1.-SP2B-on-Gravity-Hot-Diagram---Whole-House


SP2B Automatic pump – Single Boost a Protected Flow Solution

To improve the flow for a specific tap or shower (Protected Flow Solution) install the pump on the feed which supplies the specific tap or shower only. This will maintain the flow even if other taps are being used in the home.

1a.-SP2B-on-Gravity-Hot-Diagram---Protected-Flow


SP22s Two Automatic Pumps – Balanced Flow a Whole House Solution

A single Shower Power Booster is sufficient for most installations, pressurising the hot, which should balance the lower pressure of an existing cold gravity feed or the higher pressure of a mains fed pipe. A good mixer tap will balance hot & cold with a pressure differential of 4 to 1.

If you hot & cold supply are both very low pressure (or your mixer is very poor at balancing pressures), then you may need a pump on both the hot and cold.

The Whole House Solution is often the best for a family home as the benefit is throughout the house.

(15) Where do I install my pump? - Mixed System (Gravity Hot & Mains Cold)

For most mixed systems there is no problem with an unbalanced hot & cold pressure but if you have a shower mixer which needs a balanced flow, the mixer works best when you balance the hot. In some homes the mains pressure can be very high and this may unbalance the SPB even when the pump is running. In such circumstances a pressure reducing valve on the cold may be required.

SP21S Auto & Manual Pump – Double Boost

The diagram below shows how you can double boost the hot feed when you have a strong mains cold supply.

4.-SP2B-and-SP1U-on-Gravity-Hot-and-Mains-Cold-Diagram

(16) Where do I install my pump? – Combi Boiler


Option 1 of 2 – Inlet Pressure Boost

All Combination Boilers are fitted with a pressure sensor and if the pressure falls below 1.0 Bar the gas is turned off. The SPB can be legally fitted to the mains to increase the pressure and flow o stop this happening.

A single Shower Power Booster on the cold water feed to the Combi Boiler will add only 0.2 to 0.3 Bar of pressure. However a second booster, in series, will give you a double boost adding 0.4 to 0.6 bars to the pressure.

The maximum flow from a Combi Boiler is determined by its KW rating and in winter because water is colder the output is less:

24KW Combi Boiler gives 11.5 Litres a minute (2 Showers)
30KW Combi Boiler gives 14.5 Litres a minute (2.4 Showers)
42KW Combi Boiler gives 20 Litres a minute (3 Showers)

Please note the above maximum outputs of Combi Boilers greatly exceeds the output of the SPB.

The diagram below shows how to double boost the mains cold feed into a combi boiler if you have low mains pressure.

5b.-SP2B-and-SP1U-on-Mains-Supply-for-Combi-Boiler-Diagram-2


Option 2 of 2 – Hot Water Boost

The WRight Choice micro booster is the only pump on the market that can boost the pressure on the hot side of a combi boiler but you must not boost more than the maximum number of showers determined by your boiler.

The WRight Choice micro booster cannot create hot water but it can take enough hot water to create the perfect shower. A good shower needs enough water to wash away the suds and enough pressure to give a nice forceful spray pattern. We aim to give 6 litres a minute and a minimum of 3 metres head to achieve this.

The diagram below shows how a pump on the hot pipe can protect and boost the pressure to any tap or shower.

5e.-SP2B-and-SP1U-on-Mains-Supply-for-Combi-Boiler-Diagram

(17) Where do I install my pump? – Megaflow

Megaflow Hot or Cold Boost

The WRight Choice micro booster is the only pump on the market that can boost the pressure on both the hot side and cold side of a Megaflow.


5d.-SP2B-and-SP1U-on-Mains-Supply-for-Combi-Boiler-Diagram


MegaFlows were introduced as a standard for new properties in order to eliminate low pressure problems but in many cases this is the cause of low pressure problems.

If the water pressure entering your home is low or you need to feed a remote upstairs shower or tap a WRight Choice Micro Booster will protect and boost the pressure.

A Wright Choice micro booster cannot create water but you can protect and boost showers or taps in your home up to the maximum flow entering your property.

Wen others open taps in your home, provided you do not exceed the maximum incoming flow, the shower or tap you protect will continue to flow strong and good.

(18) Where do I install my pump? – Electric Shower

SP21S Auto & Manual Pumps – Double Boost

All Electric Showers are fitted with a pressure sensor and if the pressure of the incoming water main falls below 0.8 to 1 Bar, the electric shower will switch off heating elements. The SPB increases the pressure and flow to stop this happening.

Fitting a single Shower Power Booster will add 3 to 4 metres head to the incoming pressure to the incoming pressure to the electric shower, which is often enough for the Electric Shower to work.

If your pressure is exceptionally low then a double boost may be required.

A single WRight Choice micro booster on the cold inlet of a shower will protect your shower even if someone turns another tap on in your house or if your neighbours share a service to your house.

6b.-SP2B-and-SP2b-on-Mains-Cold-for-Electric-Showers-Diagram

Although one pump is normally enough, the diagram below shows how you can double boost the mains cold supply to an electric shower.

6.-SP2B-and-SP1U-on-Mains-Cold-for-Electric-Shower-Diagram

The maximum flow of an electric shower is determined by its KW power rating and in winter because the cold water is colder the output is less:

7.5KW Electric Shower – 3.5 Litres a minute
9.8KW Electric Shower – 4.7 Litres a minute
12.5KW Electric Shower – 6.0 Litres a minute

Electricity is a very expensive way of heating water so a typical family wanting the luxury of a 6.0 litre a minute shower will spend £230 a year just to heat the water up.

Heating with gas and changing to a ShowerPowerBooster boosted shower could save the cost of the electricity wasted every year.

(19) Where do I install my pump? – Radiator Booster

The WRight Choice Radiator Booster is the perfect solution if you have a dead room or a room in your house that is hard to reach.

SP1-Central-Heating-Flow-Booster

The WRight Choice Radiator Booster is the perfect solution for making the end of run radiator or group of radiators on a ‘lazy’ leg which never runs hot, run hot. They can be used for extending the central heating systems to a newly built extension.

(20) How do I link two pumps?

Two pumps can be linked together to provide either a double boost or a balanced flow – See Wire Diagrams below:

Two Automatic Pumps:

(SP22S or SP2B & SP2U)

WIRE DIAGRAM 1_Page_1


One Automatic Pump & One Manual Pump:

(SP21S or SP2B & SP1U)

WIRE DIAGRAM 1_Page_2


Pumps located in different areas of a house can be linked together with extension cables. 3m extension cables allow the pumps to be up to 15m away from the power source.

Please note that there are 3 cables running between the pumps – you will need a minimum of 3 extension cables if pumps are over 3m apart.

(28) Where can I find a plumber to fit my shower power booster?

For some customers the right plumber is you. We have designed the pumps for easy DIY and you should have everything in the box to do the job (the record claimed by a 85 year old man in Norfolk is 8 minutes to fit a pump).

However, if you would like a plumber to fit the booster for you then check our list/map of plumbers experienced in fitting our shower power boosters.

(29) Should I buy a WRight Choice Shower Head, hose or mixer?

The WRight Choice brand ethos is to give you the best solution, and if that solution is simply to change the showerhead and hose rather than fit a pump I sell the best showerheads and hoses to achieve this.

I only sell products that I would want to buy myself if I had the same objective as my customer – maximum performance at minimum cost.
We tested and evaluated showerheads and hoses in the research laboratories of Cranfield University, and we were amazed at the difference a change of showerhead or hose could make to the shower flow. The best showerheads, hoses and mixers for low-pressure situations are very good and the worst very bad, but how would you know a good or bad showerhead or hose or mixer just by looking at it? You cannot, but we test them for you, and guarantee to only sell products which work well with low pressures and all systems.

• Shower Heads that maximise your showering performance whatever flow and pressure you have.
• High Flow Shower Hoses (many new shower mixers come with shower hoses with less than 10mm internal diameter).
• If you start with low pressure my pumps can be used in multiple combinations to incrementally achieve the desired objective whatever your plumbing system.

I have set up a website with information including videos dedicated to Shower Heads, Shower Hoses, and Shower Mixer selection.

Visit The Shower Heads, Hoses & Mixers Comparison Site.

A good shower can be achieved by selling you a hydraulically inefficient showerhead, a hydraulically inefficient shower hose, a hydraulically inefficient shower mixer. As long as you also buy a big shower pump (over 20 times bigger than a SPB), you might have a good shower. The same good shower can be achieved by selling hydraulically efficient showerheads, hoses, mixers, and a small pump.

Even with the best shower hose, a shower can be spoilt by a bad showerhead. Our showerheads give wonderful multispray patterns suitable for any type of shower system as they can be set to 6 different modes to suite personal preference and any type of shower system.

Shower hoses come in different internal diameters. A high-flow shower hose allows higher flows, and will not lose you nearly as much pressure as a small-bore shower hose. Small-bore shower hoses are sometimes cheaper and are great for small electric showers and combi-boilers with high mains pressure. Changing to a high-flow shower hose may have a huge effect. Low-flow, small-bore shower hoses are not advertised as small-bore, and many customers buy them by mistake because they do not know that 2 types of shower hose exist. If the internal diameter of the shower hose is less than 10mm diameter, then it is not a high-flow shower hose.

Showerheads for electric showers create fine jets of water and need much higher pressures to operate (minimum 1 bar = 10 metres head). If you have 1 metre head, there are many showerheads which are designed for that pressure. They will never be as good as a boosted shower, but put a showerhead which is designed to operate on 10 metres head and the results are obvious. Buying the right showerhead is not easy unless you know what you are looking for, but ‘great for combi-boilers’ is a giveaway that it is only suitable for high-pressure systems. A good showerhead will probably have 100 jets and a multi spray pattern. People can buy many showerheads before they get it right, but a good showerhead is as important as a good shower hose or mixer.

Mixer valves blend hot and cold water to give you the right temperature for your shower. Many mixer valves can easily balance hot and cold water pressures in the ratio of 4 & 5 to 1 – others are not very good at dealing with differential pressure and will allow temperatures to fluctuate widely when someone turns a tap on or off elsewhere. Buying a cheap mixer tap is not necessarily a problem, and some of the worst performers are expensive mixer brands, because the parts of the mixers you cannot see can cause considerable head loss.
