Water hammer is a common problem that many homeowners experience when their toilet fill valve closes. This phenomenon occurs when there is a sudden increase in water pressure within the pipes, causing them to vibrate and create a loud banging noise. Not only can this be annoying and disruptive, but it can also cause damage to your plumbing system over time.
Fortunately, you can take steps on how to stop water hammer when toilet fill valve closes. This guide will discuss the causes of water hammers and provide solutions to prevent them. If you’re tired of hearing that loud banging noise every time you flush your toilet, read on to learn how to stop water hammer.
Understanding Water Hammer in Toilets
Water hammer results from water moving too quickly through your plumbing system and coming to an abrupt stop. It’s similar to the sound produced when a moving train abruptly stops on its tracks. In the case of toilets, it occurs when the fill valve closes after you flush.
The sudden stoppage of water flow creates a shock wave that travels through your pipes, vibrating them and making the familiar banging noise. This shock wave can also damage your pipes by loosening joints, leading to leaks and other plumbing issues.
11 Best Ways on How to Stop Water Hammer When Toilet Fill Valve Closes
1. Install a Water Hammer Arrestor:
One of the most effective solutions to stop water hammering in toilets is by installing a water hammer arrestor. This device acts as a shock absorber and prevents the shock wave from traveling through your pipes, eliminating the banging noise. This is a permanent solution, but it may require the expertise of a plumber to install. Leaving this task to a professional is best if you’re uncomfortable with DIY plumbing.
2. Adjust the Water Pressure:
High water pressure can contribute to water hammer in toilets. If your home’s water pressure is above 80 psi (pounds per square inch), it may be causing the problem. You can adjust the water pressure using a pressure regulator or installing an expansion tank. Maintaining a safe water pressure is important to prevent damage to your plumbing system. If you’re unsure of how to adjust the water pressure, consult a plumber for assistance.
3. Check and Replace Old Fill Valve:
