Every time we quickly shut off the hot water from any place in our house, or even turn the water rapidly from hot to cold, a loud THUNK sound occurs and can be heard throughout the house. We have not heard it in conjunction with either the dishwasher or the washing machine.
What is the cause of this? Are there short term fixes? What is the long-term cure?
I apologize if this has been listed before. I checked all over to try to find an answer before posting.
