Water Hammer Arrestors

Now that you're all set with the water pressure reducer, you can go over to your washing machine, faucet or dishwasher and install the water hammer arrestors. Isolation valves make the job of installing the water hammer arrestors very simple.

1. Turn off the hot and cold water lines.

2. Unscrew the hoses attached to the hot and cold water lines and at the washing machine, faucet or dishwasher.

3. Screw a water hammer arrestor to the valve of the hot water line and do the same for the cold water line. Use a wrench to securely tighten.

4. Screw a braided stainless steel hose to both the hot water line at the dishwasher and faucet. Again, use a wrench to tighten if necessary.
