I've got a pretty loud drilling noise, that I only hear in the bedroom. Not really any specific time of day, and may not hear it for a few weeks. Anyone have any idea what this may be?
That makes sense. But, this was doing it all night. Usually if I hear it, it doesn't last that long. I just wanna get it fixed..If you have copper piping, expansion/contraction while it is heating up during use can cause a creaking/drilling type noise. This occurs when the pipe is installed through a wooden stud and is bearing hard against the wood, typically when a wooden wedge has been used during installation (to prevent just this exact noise) and the wedge has loosened. The pipe bears against the wood while expanding/contracting from the hot water flowing through it.
check the pipes to and from the hot water heater, check the holes through the wood, they may need to be widened to allow for the pipe expansion.That makes sense. But, this was doing it all night. Usually if I hear it, it doesn't last that long. I just wanna get it fixed..
