Ok so mains off, clean valves & check seal is way to go?
I assume local DIY places will stock replacement parts if need be? and replacing seal etc is pretty easy?
Sorry for late reply on this, forgot all about it until noticed recently the dripping again
Went up today to have a look and we have 2 tanks that both run into the pipe thats leaking
Both have the ball valves in there and i took 2 pics below, at the moment its just dripping into the tanks...
Hi guys
Quick question - recently i have noticed our outside overflow pipe leaking when the heating system comes on (stops dripping after 30 or mins it seems)
The pipe (there is 2 together? but seems only 1 is dripping) seem to be located in the attic so assume its central heating related...
