I Want to Boost Hot and Cold

For most people a single boost on the hot is good enough as 2/3rd of the water for a hot shower is hot water and most mixers will balance differential pressure up to a factor of 5.

If your mixer needs more balanced pressures, your cold pressure is very low, or you simply like cold boosted showers, then a SPB on the hot and on the cold is required.

Detailed instructions are sent with every SPB to help you get the best out of our products and there is a fitting advise helpline, however you can, if you think you need two pumps opt for our two booster kit the SP22S now.
