And different noises can mean very different pipe issues, so it is important to diagnose the issue based on whether your pipes squeak, bang, or rattle. Quiet noisy pipes usually can be fixed by using extra anchor brackets, cushioning materials, or adjusting your water pressure.
Then, in order to fix loose banging or rattling pipes, you should first check all pipe anchoring locations. Generally, older pipe anchors come loose over time and may need to be tightened or replaced. Pipes are usually anchored to wood floor joists using metal clamps. So you need to replace these clams if they are loose, or add more clamps if the pipes are easily moved. Install anchors every 6 to 8 feet on horizontal pipes and every 8 to 10 feet on vertical pipes.
Then, add cushioning to prevent rattling or banging pipes. Wrap a piece of rubber around the pipe and secure the wrapped area to the joists with a metal clip. If you don’t have pipe insulation foam, a piece of rubber inner tube or garden hose will work. Do this every 4 feet along length of the pipe. Remember to leave room for expansion around the pipe or anchoring mechanism. This particularly important when insulating plastic pipes. Besides, avoid galvanized anchors on copper piping. Even small pipe movement can create a lot of noise when metal on metal comes against metal.
The next step is to check for lack of air. You need to check the air chambers behind plumbing fixtures for water buildup. Air chambers are designed to provide a cushion when the water is turned on and off. If the chamber fills with water, you may hear a hammer noise when turning your faucets on and off. You should turn off the home’s main water supply, drain all the pipes in the home by turning on every faucet in the house. And then close the faucets before tuning on the main water supply. This should restore air in the designated air chambers and quiet noisy pipes.
Well, how to stop squeaky pipes? You need to examine hot water pipes if you hear squeaking. Hot water pipes expand and rub against their anchoring straps when the water runs through them. The rubbing can sound like a squeaky noise when the water is turned on or off. Then, cushion hot Underground Pipe the same way you would cushion banging pipes, by placing either pipe cushioning foam or rubber inside the anchor.
