Water Hammer Arrestors..Washing Machine)

Rusty: That Oatey suppressor is Exactly the one I'm looking at if I don't build my own. Home Depot around here is sold out..OR doesn't carry that brand. My local hardware store has them for $21.99..same model number. I like the quality better than the other similar brands that Home Depot has on the shelf.

APS: That's pretty much what I am considering doing. The store bought model is easier though.

The ones that I put in work real well.

The problem with the one that APS posted is that they lose air and you have to drain them every once in a while. Also with the price of copper these days it would probably cost you as much.
The Oatey suppressor has a plunger in them at the top and air can't escape.

Good luck with whatever you do.

Looking at the Oatey Link: I like the part where everything is ("Sold Seperately")...probably including the washing machine.

Try EBay....search for Oatey 38600. One is one there for $13 plus 3.50 shipping to your door. Amazon (search for the same item) has them for $16.98 with free shipping and no gas costs to drive to Home Depot, etc. Surely you can wait for the delivery.....

This is what I did. Home grown. It's working. No more Water Hammer bangs. The original supply tubing is 1/2 inch. The "Chamber" is 12 inches of 3/4 inch tube with a cap on top and an elbow to connect it to the original tube. The washing machine and dryer are on the OTHER side of the insulated wall. The Hoses to the machine drop off the bottom of the faucets,

The "Oatey" supressors that Rusty suggested are much smaller. They have a piston inside that allows them to be positioned at ANY angle. My "Chambers" must be oriented Vertically to preserve the Air BUBBLE in the top of the chamber.

NB

PS: I would NOT recommend the procedure I took to anyone.. who is not TOTALLY confident in their skill in soldering wet tubing.

When the water is drained at island- and seasonal- cottages, those chambers can be half that length, and you could use any-old ½" tubing that is lying around. I've found that previously-soldered (used) tubing makes for easier fitting—just "tin" the new stuff with a coating of solder. To manage "wet" installations, I suggest stuffing bread into the tubing that is "leaking".

—> Soldering in cold and windy locations doesn't warm you up!

The gauge in the photo reminded me that I could have put an el-cheapo water pressure gauge at the top of one of those chambers.

In a search related to your original post, it was apparent that suppressors weren't consistent in fixing the problem, and required an occasional return to the store!
