Description
–
The noise from banging pipes is caused by shocks of high speed water flowing in the piping system when a fixture is suddenly closed. Sudden stoppage of the water (a non-compressible liquid) flowing at a given pressure and velocity causes a surge or spike of water and is called water hammer. When this occurs, a pressure wave travels back through the piping until it finds a point of relief. The LF15M2 and LF15M2S Water Hammer Arrestors are designed to eliminate this effect. The LF15M2 and LF15M2S features Lead Free construction to comply with Lead Free requirements.

Stopped water hammer from sprinkler valves shutting off
Stopped water hammer from sprinkler valves shutting off. My water line pressure is 65 lbs. These are pre-charged at 60 lbs pressure and worked perfectly to stop the water hammer noise. The competitor (Souix Chief) didn't know what their arrestors were set at so I went with Watts.

This hammer arrestor did the trick
I had big bangs under my home every time the sprinkler valve went off. Installed this near the valve and the bang was gone. All I know is arrestor really works!

Quality Product
Installed on water heater. My washing machine caused banging pipes. Put water hammer arrestors on machine. After a while started banging again so we decided to install on our water heater. Every once in a while I can still hear a little noise but not as much as it was.

Watts Knock Arrestor Is A Perfect Fix
I found that the Watts knock arrestor that I purchased to be a commercial grade, professionally manufactured product.
I am also very happy that this product worked perfectly. After an easy installation, it eliminated the hammer knock that I was experiencing. The 'knock' was being caused by my lawn sprinkler system and I was lucky to have a faucet in the same line that fed the sprinkler valves. With a separate purchase of a few brass fittings I was able to easily attach the threaded fitting on the 'arrestor' to my outside faucet. Thus eliminating the 'knock'.

Solved my problem
For years at times when city water pressure increased even though I had installed a pressure regulator on the supply line I would get water hammer when some of the sprinkler zone valves shut. Not wanting to cut into water line to install a tee I was able to install arrestor right on the hose bib with a 3/4" adapter.

Does what it should; easy to install
Have used a couple of these particular arrestors over the years. Work great; the threaded end makes the install that much easier. Just remember to keep it as close as possible to the source of the water hammer. My most recent install had to be a good distance from the valve. While this arrestor did make a difference, when compared to arrestors installed closer they are more effective.

Great product and the bottom line is: it works!
I installed the LF15M2-B, 3/4" Lead Free Water Hammer Arrestor (Threaded) to first of two sprinkler valves (incoming line) and I no longer hear the hammering noise when the valve activates watering the lawn.
