We have a fog horn sound every time we flush the toilets on all the floors and also when we run the laundry. The sound stops when we open any water tap on. It seems to happen frequently during summer time or when the weather is warm outside.During winter time its once or twice a month. What seems to be the problem?
Last summer we got the water pressure checked and the pressure was ok.
Any suggestions on how to fix this?
