    Doing a bathroom refurb and need new taps. I know having a combi boiler usually means going for taps made for high pressure, but I have a shared water main with a neighbour so the pressure can drop a fair bit at times.
    Will I be better off going for taps that say suitable for all pressures?
    Bristan taps seem to be mostly this way ...
    Also why make taps suitable only for high pressure if they can be made for all pressures?, surely they're just cutting off part of the market unnecessarily

    If you have mains pressure hot and cold then you should go with the appropriate taps. You only need low pressure taps for gravity fed systems as these are often less than 3m and won’t get anywhere near the 1bar needed (about 30ft). Even with a shared main, you will have enough pressure (assuming the right checks were done for your boiler install).

    cheers for the reply, unfortunately I don't know whether the right checks were done ...... is there an easy/accurate way to test the pressure of hot water from the boiler?

    If you have an outside tap you can measure how much water you can get in a bucket in half a minute. Most combis require 10ltrs p/m or more. Your boiler will need more pressure than the minimum for high pressure taps
