The reason I sell shower heads and hoses is a good one. I researched shower heads at Cranfield University and in order to get the best effect out of a ShowerPowerBooster it was evident that the shower head has a critical impact upon the quality of a shower.It just does not make sense to suffer a poor shower just because you have a poor shower head

Most people have a decent shower head & hose and even if they do not, the effect of fitting a ShowerPowerBooster is enough to put a smile on their face (and they may never know how much better it would have been had they bought one of my shower heads and hoses as well).
The back pressure from a poor shower head and shower hose can cause the flow to fall to below 1.5 litres a minute and at this flow rate a fully automatic SP2B ShowerPowerBooster may not activate automatically. There are easy ways to activate the pump other than by increasing the flow rate but upgrading your shower head and hose will often not only facilitate automatic operation but increase the quality of the shower when the pump is running.
Before I sold shower heads and hoses I found that telling a customer they needed a better shower head simply resulted in the customer going to the local market and buying a new shower head of equally poor design. I sell Shower Heads & Hoses under my own WRightChoice Brand.
