Frequently Asked Questions

Where should I install Oatey Quiet pipes?

They can be mounted directly to the hot and cold connections on the back of washer or to the hot and cold water shut offs for the washer. We recommend they be mounted to the hot and cold shut offs for more stability.

Can hammer arrestors be installed upside down?

Yes. Oatey hammer arrestors are gas filled chambers which absorb shock no matter what angle they are installed. 

Will the hammer arrestors ever fill with water?

No. The arrestors are gas filled and sealed with internal O-Rings. The only way that the arrestor will fill with water, is if one of the internal O-Rings fail. The O-Rings cannot be replaced and the arrestor would have to be replaced.
