Thanks Meldrew's Mate. A couple of questions...will the pump still work with the boiler off? I seem to remember the pump shuts off about 3 minutes after the boiler stops. Also, how do I bleed air from the pump? Please excuse my ignorance but is it the large screw on the centre of the pump?
I recently replaced a radiator after some decorating and now my Baxi Solo 2 overheats and trips out. It was working ok for about a week but I guess an airlock is the cause. What is the best way to get rid of the air? I have bled the radiators and the pump appears to be working ok. Thanks, Paul.
