Hi,
I have a radiator in a bedroom where I'm hearing a knocking sound coming from what I think is the valve. The valve is pretty much just a regular open and close one.
I've lifted floorboards and lagged the pipes where it touches the joist in order to stop that from being an issue, the central heating system has been flushed and bled so I can't think of anything else that could be causing this knocking. It doesn't sound like expansion noises from the brackets either.
Could the valve be faulty? I've heard that TRVs can cause problems but as this isn't one, could the valve still be an issue?
Thanks
