Does anyone know if you can convert a power shower to work on a high pressure system? I have an Aqualisa Aquastream Power Shower (about 1yr old) but have just changed from a gravity feed system to a high pressure mains fed system. I have been told i must change the shower however it was quite expensive and i will also have to re-tile part of my bathroom wall to change it. I was wondering if the motor is disconnected would the shower work?
