A Shower Power Booster is available as a single pump or in bundles of two pumps.
A ShowerPowerBooster will boost any and all systems but it is particularly useful in boosting gravity and mixed gravity systems where existing pressures are low. It will not impeded flow should there be a power cut.
The SP2B is a fully automatic pump and a single pump will be effective for most applications but we recommend that you buy a SP21S double boost or a SP22S for boosting hot and cold for some applications (click on links below).
