leaking pressure valve on my potterton combi boiler?
my pressure valve is really leaking on my potterton combi boiler.water pressure was 2.5.my husband drained some water from a radiator andit reads 1.3.but still leaks .so at the moment we are just turning the valve back on when we need hot water.
Once these pressure relief valves have been opened, they rarely seem to seal again for some reason - and the only cure is to have it replaced. Thankfully the part is only about a tenner.
