Hi, I want to buy new bathroom taps and have seen that some are for high pressure water systems, and some for low. How do I know what mine is ? What is the result if I fit the wrong ones ? We have a Worcester 28i combi boiler (if that helps in any way). Any feedback would be much appreciated.

Tank fed = Low pressure
Mains fed = High pressure

Man difference is that there are non return valves fitted to the high pressure taps

Worcester 28i is a combi and therefore hot and cold are at Mains pressure and there is enough to force open the non return valves

Thanks... we were having a problem with the hot water in the one bathroom never getting hot enough. A guy came out and said the flow rate through the tap was too high and if we turned the tap to 75% on then it would be very hot. Seems to have worked, but I thought that maybe it was a problem with the "wrong taps".
