Noisy banging pipes can be an annoying and sometimes alarming problem. The banging sound is caused by water hammer, which occurs when water flow is abruptly stopped or redirected, causing a shockwave in the pipes. However, air pockets in the plumbing system can also cause similar banging sounds. The good news is that both water hammer and air pockets can be fixed with a few simple steps. In this blog post, we will discuss how to quiet your noisy plumbing pipes.
Step 1: Check Your Water Pressure
High water pressure can cause water hammer. To check your water pressure, purchase a pressure gauge from a hardware store and attach it to a hose bib or laundry tub faucet. The pressure should be between 40 and 60 pounds per square inch (psi). If the pressure is higher than 60 psi, you will need to install a pressure-reducing valve.
Step 2: Install Water Hammer Arrestors
Water hammer arrestors are devices that absorb the shockwaves caused by water hammer. They are typically installed near the shut-off valve, where the water enters the building. To install a water hammer arrestor, turn off the main water supply, drain the pipes, and then attach the arrestor to the pipe using compression fittings. Turn the water supply back on and test to see if the noise has stopped.
Step 3: Check for Air Pockets
Air pockets in the plumbing system can also cause banging sounds. To check for air pockets, turn on all the faucets in the house and let them run for a few minutes. This will allow any air pockets to be pushed out of the pipes. Once the water runs smoothly, turn off the faucets.
Step 4: Secure Loose Pipes
Loose pipes can vibrate and cause banging sounds. To secure loose pipes, you can use pipe hangers, clamps, or straps. Install the hangers or straps at intervals along the pipe, ensuring that the pipe is snug but not too tight.
Step 5: Call a Plumber
If the above steps do not solve the problem, it is recommended to call a licensed plumber. A professional plumber will have the tools and expertise necessary to diagnose and fix the issue. They may need to replace a faulty valve or section of piping, or install additional water hammer arrestors or air chambers.
In conclusion, noisy banging pipes can be a frustrating problem, but it can often be fixed with a few simple steps. Check your water pressure, install water hammer arrestors, check for air pockets, and secure loose pipes. If the problem persists, do not hesitate to call a licensed plumber. By taking these steps, you can enjoy quiet and peaceful plumbing in your home.
