HELP
I have a rattling sound in my heating system which seems to be coming from the C/H pump. it only happens when the C/H is on and then it is intermitant. I have tried turning the pump down but it only has limited effect. It stops it for a short period of time (2 mins) and then starts up again
sometimes the noise dosent happen at all and it only seems to happen when the system is warm.
could it be the barings and i need a new pump

Sounds like you have a Garvity fed hot water and pumped CH system, so the pump will only run when CH is on. Therefore, new pump me thinks.

depending on its location, could it be air trapped in the pump (may be excasperated when hot). Have you tried bleeding the pump?

If not, then agree - sounds like new pump
