Main Mersey Super makes very loud noise

Hi Folks,

I have a bit of a problem with my MainĂ‚ Mersey Super multipoint water, very often it makes very loud noise. It is so loud I can hear it on the second floor. I don’t think it is normal as when it was installed I could hardly hear it. What might be causing the problem?


Hi Dan

It looks to me that your automatic valve is causing this problem. How old your boiler is? If it is still under warranty give it back if not you can always replace automatic valve.
