Sioux Chief 652-A Water Arrestor

Perfect fit easy to install stopped the knocking

Used these to replace the old type AAA Water hammer arresters. They stopped the water hammer at the wash machine that was going throughout the house. We needed the extra volume to compensate and eliminate the hammer effect. Well made. The piston works well and should last a long time. A good value for the money. It took numerous fittings to replace the old setup. But one of the previous reviewers showed a good way of accomplishing this and he had pictures.

I don't usually write product reviews. But, I am very impressed by these water hammer arrestors. When our sprinkler valves would shut off, the line between the kitchen sink and the ice maker in the fridge would rattle with some fury. The sprinkler valves are a long distance from the kitchen and I was worried about the potential for pipe damage. As our copper pipes are in the slab, a leak would be a pain to fix. Installing the 652-As took just a few minutes as I already had pipe Ts in the lines. I installed one in the front yard near the sprinkler valves and one in the back yard next to a sprinkler valve. After installing the 652-As, our water hammer issue completely disappeared and our pipes are silent when the sprinkler valves close. Only thing I regret is not installing these years ago.

My old house has the usual "air chamber" type water hammer arresting pipe extensions above every faucet and fixture. But I recently switched the house from a private well to the village water supply, and with this came much more water pressure and also greater flow. I started to have water hammer issues where I never had before, mainly in a few places that had automatic valves (e.g. the cloths washer and the outdoor faucet that has a timer that controls watering; in those places the valves close quickly. I was faced with upgrading my existing 'pipe extension' type air chambers in hopes of eliminating the water hammer, or switching to proper water hammer arrestors. These are devices that are essentially little shock absorbers that work on the water in a pipe, and which cannot be "water logged", and thus can be expected to work for a long time without attention or gradual degradation in performance. I decided that if I was going to cut into pipes and do soldering, that I would go for the better solution. I chose Sioux Chief because they seem to be one of the major manufacturers of these products. But I learned that while many stores (Home Depot, etc) carry these products, that they are actually supposed to be selected based on static water pressure and actual water flow at the location (faucet) in question. I bought (on Amazon) two inexpensive meters to measure pressure and flow...see my other reviews of those products. I reported my findings to Sioux Chief via their inquiry form, and their technical support advised on which model arrestor I should use for best performance in my situation. The 652-A arrestor reviewed here is the one they recommended for the outdoor faucet, while a different model was deemed best for the clothes washer. The arrestors of any given size can be purchased with various connections, such as basic soldering type (the small end of the arrestor is sized like a copper pipe end, and you solder directly to the arrestor), plus screw fittings and another kind of fitting that I had never seen before. I chose the regular screw fitting. My work involved cutting the existing copper pipe just above the "tee" where the existing air chamber pipe extended up from the faucet, and soldering on a pipe fitting of the correct size. Then I just screwed the new arrestor onto that fitting, and the job was done. I thought this was preferable to soldering directly onto the arrestor, since excess heat can possibly damage the internal plunger or O-rings or whatever. I don't solder pipes professionally and figured that I might heat the arrestor more than a professional plumber would. I also like being able to quickly remove and/or replace the arrestor without doing any more soldering. I have not noted any more water hammer since I installed these arrestors, so I think they are doing their job.

Works great on my sprinkler system,stopped the water hammer

Sometimes people use the 1/2" models near the fixture in question. I prefer a couple large 1" models as a central arrester. The Sioux Chief models are my go too. They last a long time - but nothing lasts forever! I prefer to put these behind access plates so they can be replaced. Just a word of personal advice. Will buy again.

I bought two of the Sioux water arrestors and installed them at the water shut off valves for our washing machine. They substantially improved the banging of our waterlines. Not complete elimination but a good improvement. Due to a leak at one of the hose connections (which had nothing to do with the arrestors) I had to remove both of them. This was after about a month of use. Upon inspection I noticed that the piston in one of the arrestors was all the way to the back of the cylinder. I tried to bring it forward but no dice. At that point I cut the arrestor apart. The plastic cup/piston was stuck in the back. Likely a seal was leaking and the air behind the piston escaped at which point the arrestor becomes useless. Very disappointed. Just a bit more than 30 days of use. Would not buy again.

Bought a new GE washer, dryer combo and the pipes in the wall were banging a lot. After purchasing some off brand smaller arrestors that did not work I purchased these large ones hoping they would help. They do help a little bit better but still get pipe banging in the wall.

After the arrest was fixed near where the noise was heard, the banking noise became a series of vibrations. I have removed the arrestor/

This product worked well. It is used on the hot water pipe. The only issue is I had to use a liquid thread sealent to stop a slow leak. No more hammering.

J'ai acheté cet item pour remplacer un semblable qui n'avait jamais très bien fonctionné. Celui-ci fonctionne à merveille: plus de coup de bélier instantanément. Excellent achat. J'en ai acheté un autre pour mettre sur une autre ligne d'eau.

A few years ago we installed a brand new washing machine in our 100 year old house. When using the delay timer (to ensure the washing was ready for hanging on the line after breakfast), we were woken every single morning by banging, as the high tech new machine turned the water on and off with such force that our rusty old plumbing could not cope. After months of research I solved the problem with a Sioux Chief mini-restor. Unfortunately we had a brand new kitchen fitted a couple of years later, and the complex helter-skelter of new pipes under our sink caused the problem to return. This time neither buying a new mini-restor, fitting it to different pipes, nor using two water-hammer arrestors at the same time solved the problem for very long. I eventually found this larger, more heavy-duty version. It is less DIY-friendly than the smaller arrestor, and took several attempts to fit successfully without leaking. I had to buy a brass T-connector, an adapter to fit this to one end, and another adapter to fit the washing machine hose to the other end of the T. I then had to cake all joins in PTFE tape and silicone, and wait a week before turning the water back on. Finally we can sleep through the night once more.Worth every penny and hour of effort.

Tenía golpe de ariete en la tubería por las mañanas cuando había más presión y el tanque de agua se llenaba. Lo instalé aprox 25 cm en la tuberia del tanque de agua antes del flotador. El problema se solucionó! Lo único malo es que tardó como mes y medio en llegar.
