I seem to have water leaking from outside overflow pipe that is running from the hot water tank, based on first floor.
My house is economy 7 & where hot water/immersion tank is, there is a small plastic pipe leading to outside house, which is leaking water and running down front of house & into lounge ceiling.
The water stopped leaking when i switched mains water off.
Please can someone tell me why water is leaking from the pipe (overflow)running from hot water tank to outside house? No water seems to be leaking inside house but only from hot water tank pipe leading outside.
