Rated 5.0 out of 5.0 by Mikey Better than expected...
Recently purchase a high efficiency GE washer. I had read reviews that said these newer models cause much more water hammer. Sure enough, it was way more noticeable than our old washer. I saw these and though they looked pretty tiny, I figured I'd give them a try. The package indicated a 60 psi max on the water line to be effective. I'm running 65 to 70 psi but these seemed like the easiest solution and were not expensive. Ya for me, they worked perfectly! Water hammer that could be heard throughout the house has been reduced to just "clicks" that can be heard only in the laundry room. Can't say how they might work for you but they worked better than expected for my situation.

I recently purchased a new LG washing machine but my pipes started hammering something fierce. I installed this item and the problem immediately went away.

Rated 4.0 out of 5.0 by TNS Good - But needs low water pressure.
LG washers need to have low water pressure to reduce water hammer. The water valves slam shut very fast. Probably designed for low water pressure. Water pressure regulators worked to solve the high pressure issue with a LG washer. The water pressure to the house is 100psi and we don't have a pressure reducing valve on the water supply line. The water hammer from the washer is very bad. I replaced the water hammer arrestors from HD and that helped for a while. It seems the arrestors will not work with high pressure after a few months. So in checking on-line, this seems to be a common problem with the LG washers. Instead of installing a water pressure regulator on the home water supply, I decide to try these pressure reducers. Great improvement. But the water hammer arrestors were still not working well. But, after having installed the pressure regulators and waiting a month to replace water hammer assrstors, all is well! It seems the water hammer assestors recovered after having 40 psi water pressure for a month. Happy camper!

Rated 5.0 out of 5.0 by Joe Ignore the other reviews
I'm mystified by the bad reviews. I came here to specifically write a good review because I love this product. Its the type of product that had me thinking 'wow this thing just works'. When my new HE washer was running before I could hear it two floors away. Now its whisper quiet, almost no sound at all other than water swishing. My washer seemed to really have a strong valve, and slammed that thing shut. I'm thinking that people who this did not work for, perhaps their problem is behind the walls and have pipes actually moving and banging (which this will help reduce their movement) but if the pipes are already not secure just the pressure of water flowing might be shaking them. Installation couldnt be easier.

Got a new washing machine that was causing severe water hammer. Bought this product and installed only to find that it did almost nothing. Problem continued at about 95% of original level.
I definitely would not recomment this device as it simply does not work. I replaced it with the Sioux device for same, and it completely solved the problem.

This product works BUT does not remove the problem completely.
However for the cost you spend VS the benefits you get it totally worth the moneys.
A homeowner should do all he/she can to help prevent future water leaks in the house.
20-30$ for this device is well spent.

Don't know what to say, it did not stop the water hammer effect from our clothes washer. In all fairness, it may just be that the electric valves of the washer are creating a problem too severe to be fixed by using this device.
