Hi,
I think my 12 year old central heating pump may be dead.
Symptoms are...
Heating will work for a while then start to gurgle at the boiler
Boiler starts to hiss as if the water is not moving around the system
Pipes start to bang near boiler and near the pump
Central heating boiler cuts out.
If I tap the pump I can hear a gurgle eventually the central heating will come back to life but start the same symptoms show again in 30 minutes or so.
I had a plumber out to see it and he said the pump could have dirt in it that is stopping it running correctly, used the bleed valve to get the pump moving again, charged me £40 and left.
Before I either pay a plumber or maybe tackle this myself do you guys think it is the pump at fault here or maybe an air lock of some kind?
