The ShowerPowerBooster was invented by Alan Wright BSC Hons CEng MICE and appeared on Dragons Den in 2013. It is a patented pump which gives the same results as pumps x20 bigger with just 12 watts of electricity. Thousands of these pumps give great showers and tap flows all over the world every day.

A Shower Power Booster can be fitted in minutes without modification of your plumbing by any DIY enthusiast to give you the same output as traditional power showers. These pumps pump well above their weight to boost the flow throughout the house, but it is the simplicity of fitting and no need for an electrician which will allow you to solve your pressure problem at half the cost of traditional pumps. A single pump can boost the whole house. We invite you to read our excellent reviews on Trustpilot.

The Shower Power Booster will boost electric showers to stop them dropping out when the pressure fluctuates, and the same thing for showers fed by a combi boiler. They are the only pump that can be fitted on the hot side of a combination boiler to boost a shower. With its extreme durability, pressure rating, and temperature rating, it is suitable for boosting lazy radiators, and even high temperature heat sources such as wood burners, Agas, and solar thermal.

This quiet pump does so much more than a traditional pump, with a patented fail-safe to original flow if you have a power cut.

WRAS Approved, it was awarded Best Water Innovation by Imperial College London at the Institute of Physics in 2012. It is manufactured exclusively in the UK by Flowflex.

We have hundreds of positive testimonials for this truly amazing invention.

Just fitted the SPB and am absolutely amazed and impressed. On seeing its size my heart sank as I thought there was no way this small thing could fix the problem. I have purchased 3 electric showers over the last year and none have worked correctly due to low pressure. Despite its small size the pump does exactly what it says on the tin and provides me with a more than adequate shower at constant temperatures. Goodbye scalding/freezing showers, hello cleanliness :) Seriously its fab and Alan’s c…
