Overflow pipe from tank in attic.

Unless your pressurised hw system is in the attic too then it could be a blowoff safety valve no idea about heating system the heating is run from a stanley oil fired cooker don t think it s pressurised though. If not then u will still have a expansion tank in the attic with an overflow. The tank in the attic has been trickling out of the overflow for a few weeks now. Set it very low but water is above the float.

I think you might be right about the tank on the landing. With this type of valve the brass stem is bent downwards carefully to adjust the water level. The overflow pipes from the tanks in the loft generally come out at the eaves so it unlikely to be them. They re a vital part of your home s plumbing system.

Have already changed the valve and float in the attic. If this leak is very recent then the ball valve needs a new washer as the tank is overfilling. Tested it fine know it shuts off the feed that way. It could be that tank or it could be a toilet overflowing.

The tank will either be your cold water header tank or the flow and expansion tank for the heating system and the valve is a type 1. If its the toilet it will be directly connected to the white overflow pipe so should be easy to trace. If the water in the tank or cistern fills up to a higher level than it should the excess water flows down the overflow pipe and runs outside rather than leaking into the room. I have an open vented system with a hot water pump stuart turner monsoon twin 3 fitted.
