We are experiencing a groaning/vibration coming from water pipes. We had the water shut off for 2 days while installing a new water heater. The groaning started after the water was turned back on. We have tried turning the water back off and letting the pipes drain through the faucets and then turning it back on. I have noticed that if I turn the valve off to the toilet the groaning will stop. Any ideas? Thanks in advance.

Sounds like the toilet fill valve is leaking. Maybe some junk got dislodged with the water heater replacement and made its way to the toilet valve.

Whenever you shut the water off, once it is turned back on again, it dislodges various stuff in the pipes. That can give valve seats a problem. Depending on the toilet valve you have, it may be repairable easily, and it may only require taking the seal out, wiping away any debris, and putting it back on. On many (Korky, and Fluidmaster come to mind), it's a no-tools, couple of minute fix. Worst case, you replace the seal, which is easily available at most big box stores and any good plumbing store. You might want one of those on hand, and just replace it...a few bucks verses $10-20 for a whole valve. If what you have is not repairable, then just buy a new one. Doesn't take a huge amount of skill, but it will need to be adjusted once installed for your particular toilet.
