    Q:Do I need 2 of these for my washing machine, one for the hot and one for the cold water pipes?
    by|Jun 8, 2022

    Answer This Question

    A:  You don’t “need” any, but you would be wise to use two, one on each water line.  When the washer’s valves turn off, they do so very suddenly.  This leads to a pressure surge.  These water hammer arresters reduce the magnitude of these pressure surges, which reduces the stress on your pipes.  I regard these arresters as cheap insurance.  They may also reduce the noise when the washer’s valves close.

    by|Jun 10, 2022

      A:  It would depend on which line the water hammer is on.  If you cannot determine which has the hammer, then I would suggest you put one on each line as a safety measure.

      by|Jun 14, 2022

        A:  yes, 1 for hot and 1 for cold.  You will not regret purchasing these.  I wish I would have bought them years ago when the washer was installed, would have saved a lot of headaches from the banging pipes.

        by|Jun 11, 2022

          A:  Yes - worked well for me.

              I put these on the lines to the washing machine. I cannot notice any improvement. They are not completely vertical, but that's the angle I got with the fittings at HD.

              Don't bother. Buy a Sioux Chief brand.
              I bought two of these to silence the severe water hammer caused by my new LG washer, which was audible over the entire house -- upstairs and downstairs. At first, it seemed like it was improved about 25%, so I didn't bother returning them. After 3-4 months, it was as bad as ever. A year later, I decided it was time to try again. Bought two, Sioux Chief 660-HB for hot and cold for $14.50 each and the result was amazing. Water hammer is only slightly audible. The hot water side seems worse, so I'm already planning to replace that cartridge with the larger Sioux Chief 652-A, since they simply unscrew with a wrench and are same size fitting.

                After installing our automatic rainbird sprinkler timer our pipes would bang after the water would shut off. This was easy to install and has fixed the issue. Very happy with this purchase.

                  Worked immediately
                  Our new washer caused more water hammer than older one. I saw good reviews for these Arrestors and bought two of them. I put them on yesterday and we now here no water hammer. Very easy to install. Simply turn off the water supply valve, disconnect washer water supply hose, connect Arrestor to valves, connect washer hose to Arrestor, turn on the water. Done. We've heard no "clunks" since installing the Arrestors. I installed one on each the hot and cold water supplies.

                    Just what the Plumber ordered.
                    I read the reviews and And purchased this product because of the positive feedback. I bought and installed a pair At my house because the pipes started knocking when I installed a new washing machine. After reading the reviews I thought I should install them on the back of the washing machine So they would be vertical And have the flexible hose between them and the rigid copper pipe at the hook up. The connections at the back of the washer were too close together so I had to do it at the hook up. They’re installed horizontally and work just fine. They have even stopped the knocking in the bathroom sink 30 feet away.

                        Severe hammering at outside water spigot after installing Rain Bird sprinkler kit and raising water pressure from 40 to 70. Installing this water arrestor on the spigot immediately fixed the problem. Happy customer!

                        We retired and bought a pier/beam house in Florida. Extreme water hammering when running the washing machine. I purchased two of these items and installed one of them on the cold side of incoming water to the washer. Installing the device on the water tap was only possible if the device was horizontal and not vertical. It did not stop the water hammering. I crawled under the house and saw lots of pipes (PVC) bouncing around (scary) when the hammering occurred. I was thinking I would replace everything with PEX or maybe install a bunch of pipe hangers or securing devices on the pipes that are on the ground. All sorts of ideas and dollar signs were swirling around in my head. I re-thought the installation of this device on the washer AND...looked to see if I could install them ON the machine instead of the faucet. Yes! So, I installed a device on the hot and cold inlets on the washer. WOW - the water hammering TOTALLY stopped!!! The website for this device says that it doesn't matter which direction it is installed - but it made a difference at my house !! And this wonderful device save me a lot of money and work! I highly recommend it and hope it works as well for you as it is doing for me.
