What you get when you buy a SP2B

The Shower Power Booster Range
The Shower Power Booster is sold in kits of one or two pumps so that you can single or double boost or achieve the equivalence of a twin impeller pump.

The SP2B is used as a single boost for gravity and electric showers, taps, and combination boilers. The ideal pressure boost for your home is often just a single SP2B but the perfect shower can be achieved by combining SP2B with other Shower Power Booster units.

SP1 – Single Boost Manual Shower Power Booster (best for negative head situations)

SP2B – Single Boost Fully Automatic Shower Power Booster (our most popular choice)

SP21S – SP2B + SP1 for Fully Automatic Double Boost (best for gravity hot and mains pressure cold)

SP22S – SP2B + SP2B for single boost on hot and cold (best for gravity systems and protecting Combi Boiler fed taps and showers)

SP22S + SP1U – Double boost hot and single boost cold (best for challenging shower mixers with high pressure requirements)

The Shower Power Booster Upgrades
SP2U – Fully automatic pump but with no transformer

SP1U – Manual/Slave SPB but with no transformer.

If you buy a SP2B or a SP1 you can always upgrade with a SP1U or a SP2U
SP2B + SP1 = SP21S
SP2B + SP2U = SP22S
SP1 + SP1U – Manually operated single boost on hot and cold or double boost if placed in series.
