Hi folks, hope you can help.
I've got a Potterton Prima boiler and a Myson CP53 pump. Lately the pump has been making grinding noises but the CH and HW both work fine so I've put off replacing it.
Last night the pump sounded terrible then the boiler started making banging sounds and the cover was too hot to touch. Water also started to come out of the overflow into the garden. Same thing happened this morning when the timer activated the HW.
Is the pump failing causing the boiler to over heat and the expansion tank to overflow?
Any advice gratfully received
