So....I have an issue with water pipes that groan, sounding something like my Mother-in-Law. Sometimes, I will run a faucet, flush a toilet, or take a shower and there is a loud, prolonged groaning sound that's audible throughout the house. If I turn on a faucet while the groaning is occuring, the noise will stop, but frequently starts again as soon as I turn off the faucet. Sometimes the noise goes on for more than 10 minutes. I notice the problem during the summer months when I have my garden sprinkler system activated, but the noise occurs even if the sprinklers are not actually on. The problem is inconsistent and I've checked the sprinkler feed line to ensure it's secure. The sound is coming from the area around my utility room where I have the water heater, main water line, and sprinkler feed line.
Thanks for any suggestions.
I don't know if you have received an answer elsewhere, but there could be a few things causing the "groaning" in your plumbing.
1. Your vent for the plumbing system could be plugged. Checking this requires a trip to the roof, so it may be a job that you would like to leave to a pro. Not only do you risk a fall, but if you find it is clogged, and attempt to run a snake through it there is always a possibility of causing damage inside if the snake takes a detour.
2. You didn't mention how old your house is. If it is an older house it may not have air chambers built in to the end of the plumbing runs to prevent water hammer.
3. It may have air chambers on the runs, but they may have become waterlogged. If that is the case you would want to turn off the water where it comes in to the house, then open every faucet in the house so the water will drain out completely. Once the faucets are open flush any toilets , then let it set for just a while so the water can drain out. Go around, and close all of the faucets, open your main valve, and let your system refill. This will allow the air chamber to drain out, and when you turn the water back on it fills the chambers with air.
With the pipes "groaning" it sounds more like a vent problem, but the way diy stuff goes for me, I never assume anything. After 44 years of working on remodels, and rebuilds I know ,that I don't know anything. As soon as you start getting cocky thinking you are good at something you will run across something that will leave you scratching your head.
I sure hope this will be of some help to you. Good luck.
It would be good to hire a pro to check your piping system, as you would not know if there is more to it. It may not be cheap but it could be worth it. Sometimes you may think that the pipes in your house may be straight forward, but there might be more to it. I recall that we had the same experience with the pipes at home. I initially wanted to do it on my own, good thing my brother who is an experienced plumber, was visiting and took a look at the system. It was later found out that some built in storage was about to collapse, and made a pressure in one of the major pipes, which causes the latter to rattle and groan.

I read with interest replies to your questions on groaning water pipes. I
have a similar problem that occurs only with one water appliance - the toilet
in my back bathroom. No other water source makes my pipes groan. My house is
older - built in the late '40s, but the back bathroom is part of an addition
done in the '70s. This problem used to occur only in the spring and fall, but
since last fall, it's all seasons.
When I flush that toilet, the pipes start to groan as it
finishes refilling, To stop it, I have to turn on the back bathroom sink cold
water faucet (the shower also works) and let it run for a few minutes, then
very slowly and painstakingly turn the faucet down until off. I was going to
try your suggestion and shut the water off at the street (there's no in-house
shut-off), then drain the system and flush the toilets as well. I'm guessing
you mean the cold water for each tap will work, since I'd rather not drain my
hot water heater.
I have experienced the groaning before and it occurred when I flush the toilet. After it has been filled up again, then the sound will disappear. I never bothered about it as it lasted only for a few minutes. However, for your case, it looks like quite a serious problem. I think you should consult a pro like a plumber near Sydney to solve your problem once and for all before it drags to something even worst.
I recently replaced a cartridge for my bathroom faucet.....everything was fine for about a month..now my faucet is groaning (I can feel vibrations in the faucet) in the off position only
