If you’ve ever experienced the loud banging sounds in your plumbing, especially when your toilet shuts off after a flush, you might be dealing with water hammer. This phenomenon occurs due to the abrupt stopping of water flow, which creates shock waves. Installing a water hammer arrestor can resolve this issue and make your plumbing system operate more quietly. In this guide, we will walk you through the steps to install a toilet water hammer arrestor yourself.
What is a Water Hammer Arrestor?
A water hammer arrestor is a mechanical device that absorbs shock waves caused by the rapid stopping of water flow. These devices work by using a chamber filled with air or gas that compresses and absorbs the pressure changes when water flow is abruptly interrupted. This prevents the loud banging noise and potential damage to your plumbing system.
Why Install a Water Hammer Arrestor?
There are several reasons why someone might choose to install a water hammer arrestor:
- Noise Reduction: The primary benefit is significantly reducing the noise associated with water hammer.
- Protection: It protects your plumbing system from potential damage caused by the pressure changes.
- Extend Lifespan: By protecting the plumbing components, you can extend their lifespan and avoid costly repairs.
- Improve Comfort: A quieter bathroom experience makes for a more pleasant home environment.
Tools and Materials Needed
Before you start installing your water hammer arrestor, gather the following tools and materials:
- Water hammer arrestor
- Adjustable wrench
- Screwdriver
- Teflon tape
- Bucket (to catch any water)
- Rags or towels
Step-by-Step Installation Guide
Step 1: Turn Off the Water Supply
The first step is to turn off the water supply to your toilet. Locate the shut-off valve, typically found behind the toilet near the wall, and turn it clockwise until it stops. It’s a good idea to flush the toilet to empty out the tank and bowl as this will make the installation process cleaner.
Step 2: Disconnect the Water Supply Line
Use the adjustable wrench to disconnect the water supply line from the toilet’s tank. Place a bucket underneath to catch any residual water that may spill out. Once disconnected, ensure that the area is dry by using rags or towels.
Step 3: Install the Water Hammer Arrestor
Now it’s time to install the water hammer arrestor. Most arrestors are designed to be connected directly to the water supply line:
- Start by wrapping the threads of the arrestor with Teflon tape to ensure a watertight seal.
- Attach the arrestor to the water supply line that goes into the toilet. Make sure it is securely tightened, but be careful not to overtighten as this can damage the threads.
- If the arrestor has multiple connection points, refer to the manufacturer’s instructions to ensure it is connected properly to the plumbing system.
Step 4: Reconnect the Water Supply Line
Once the water hammer arrestor is in place, reconnect the water supply line to the toilet’s tank. Again, wrap the threads with Teflon tape before tightening to prevent leaks.
Step 5: Turn the Water Supply Back On
After everything is securely in place, turn the shut-off valve counterclockwise to restore water flow to the toilet. Check for any leaks around the connections. If you spot any, tighten the fittings slightly until the leaking stops.
Step 6: Test the Toilet
Now it’s time to test the toilet to ensure everything is functioning correctly. Flush the toilet a few times and listen for any water hammer noises. If the installation was successful, the banging sounds should be eliminated.
Conclusion
Installing a water hammer arrestor is a straightforward DIY project that can save you from the annoyance of water hammer and the potential damage it can cause to your plumbing system.
