#129513 Whirlpool WTW 5300 Auto Temp Control (ATC) water hammer issues.

Posted by Birdboy48 on 03 September 2009 - 01:00 PM

Thanks gang !

I went to Lowes and picked up a pair of the above mentioned devices (you will need one for each hose) and while I wondered if they would work, given the severity of my problem, they did the trick.

I live at the bottom of a hill, at the end of the water line, and as a result I do have high water pressure. I suppose I could have cranked my outlets down to a point where I had less pressure, but I wanted to retain my flow rate, so I went with these first.

What I found interesting is that these devices are made specifically for washing machines, so it's pretty clear that the problem is widespread, and I'm not the only one who has these issues.

I installed them on the back of the machine as the instructions suggested, and this stopped the thrashing of the supply hoses. The connecting pipes on these devices are a bit long, so a person might lose a few inches of clearance in the back. If this is an issue, they can also be installed where the supply valves come out of the wall. However the instructions indicate that your hoses will last longer if you install at the back of the machine, so that's the route I took.

These devices apparently use a piston with an O-ring that rides up and down in the damping cylinder. The same company makes dampers (a bit larger in size than these) that will screw into a standard 1/2 pipe, and ones that can be soldered into copper pipe, and these could be used for other applications.

At $10.45 each, they seemed a bargain.

Thanks again to all who helped me solve this problem. :- )
