Hi I moved into a new house and noticed that my power shower was very weak. Under advice i installed a Surrey flange but i have since read that a surrey flange should be used with a pump above the tank because it restricts the flow. I have read that an Essex flange would be far better and increase the pressure of my shower. Does anyone know the answer to my problem? would an essex flange be worth installing? Also, i have heard that my pump should be a maximum of 4 metres away from the hot water tank. Mine has about 9 metres of pipe between the pump and the tank. Should i move it to improve things ? Any help is much appreciated as no one has been able to answer this problem so far. Kind regards John ps If you need any help on 3G telecommunications then i am your man. Its the only thing i am good at.
