Can’t Find the Mains Water Valve…

Hi, I’ve just bought BISF house that needs some work.
Started the renovation and it may be funny but I cannot locate the mains water valve to start doing work on bathroom pluming.
Any suggestions where it could be?

Thank you,

  1. Hi and welcome Roman, mine is hidden quite well so I guess it might be in the same place as yours! It’s under the kitchen sink, near floor level and half hidden in the boxed-in bit around the soil pipe. It’s on the window side of the soil pipe. I don’t know if they are always in the same place.
