I've found some posts regarding rumbling pipes, however, my situation is a bit different. They started rumbling yesterday only when the water is shut-off. It occurs with every faucet, toilet and shower in the house.
I've never had any issues with the plumbing in my home... perhaps now is the time?
Any suggestions or insight is greatly appreciated!
Re: Rumbling Pipes
It sounds like water hammer. If you've never had the problem before, then I suspect that the air buffer tubes have become waterlogged. Turn off the house main, open a couple faucets and an outside hose bib for a few minutes. Close the faucets and hose bib and turn the main back on. By draining the water out of the system, you're restoring the air in the buffer tubes which should stop or reduce the noise you're hearing.
