Hi All,
My main 4" soil stack is outside the house and vented. I'm putting in a downstairs loo which will connect into the stack lower down into a multi connection chamber.
Would I therefore need to put an air admittance valve in the downstairs toilet room. Ideally I dont want to do this as I then need to 'hide' it away so it isnt seen in a small room.
