Hi,
I replaced my criculating pump yesterday as it was making loads of noise. The job went ok, I followed the instructions and bled it before use.
Now there is a gurgling noise in the radiators and boiler. Last night I had to bleed the rad closest to the pump as it was mostly full of air (only the very bottom was warm). This morning I had to bleed 3 of 5 radiators in the flat, they all had loads of air in. The other 2 were fine. There is still the gurgling noise. Can anyone suggest why this is happening? I checked the pump conectors for tightness and leaks and everything was fine. I never had to bleed the rads much before I changed the pump.
On a plus side the new pump isn't noisey!
Pump is grunfos, boiler is potterton nettaheat electronic.
Thanks in advance.
