I have a leak that materialises into my middle floor bathroom, through a 'pull string' liht switch of all things. Directly above the light rose would be my upstairs en suite.
The water leak is quite bad now, but only happens after the shower in the en suite is used. Access to under the shower tray is poor, but the shower tray trap is always free flowing and I can see any obvious leaks under this or under the waste pipes which go away from the leak area anyway.
If its the water pipers themselves, why would they only leak when the shower us used. Because the water feed is under the floor boards and the downstairs light rose clearly has a hole in the ceiling for the elctrical wire to come through I can understand why this is the conduit for a leak, but do I need a plumber and an electrician?
Any advice will be gratefully recieved
