Why does my boiler make a pressure air squeak sound after cold supply turned off?

Anonymous user 23/02/2024 - 3.26 PM

If I flush my toilets and they have filled, the boiler makes a loud pressure squeak sound upon the instant the toilet tank fills. The same with cold taps, i run a cold tap and turn it off, same sound from boiler. I've changed both my toilet valves but no luck. Still the same issue. No one one knows what this is. Homeserve plumber came and said it's normal and fled off. I have no water meter fitted and I have a water hammer arrestor fitted on the boiler. It's a Worcester boiler and was fitted in October 2018. This pressure air squeak sound only happens on cold supply and it's driving me mad. Very loud during night if someone goes toilet. It sounds like a trapped air sound from boiler. It's started happening in last 2 months and I'm baffled. I've even drained out pipes but no luck. Please help and advise.

Are you a tradesperson and able to answer this question?

It sounds like it’s the gland in the stop tap has become loose, once they start to free up inside the tap they Begin to rattle and sends vibrations down the pipes making a noise that you’ve specified. Without actually been there to test the appliances, I can’t fully diagnose the issue.

You shouldn’t really get a sound from the boiler if you’re only running cold water so maybe a non return will need to be fitted and you won’t have a air lock on mains water supply or would need to visit to see what is happening
