Discuss Can the ballcock valve 'stick' shut due to hot weather? in the UK Plumbing Forum | Plumbing Advice area at PlumbersForums.net

Our attic water tank (which is boarded in and not easily accessible) decided to stop filling up today... (we couldn't hear it filling up) and with the temperature outside reaching 32+ I am wondering if this might have caused a problem. The temp this evening outside has gone down to 21 degrees outside... and all of a sudden we could hear the tank filling up again.

Is it possible that the hot weather and increase in attic temp has caused the ballcock to stick?

Or... could low water pressure cause this (added to the rise in temp) - although the water pressure seems to be okay (albeit slightly lower than normal).

This issue arose about a year ago. Does anyone have an idea why I occasionally hear (about once every hour or longer) a hammer related noise coming from my copper water pipes when no water is being used? It basically sounds like the noise you hear after the water shuts off when your toilet bowl...
