Product review (4 stars): Perfect Oatey Replacement but buy your own O-rings
I purchased this valve to replace an existing Oatey valve behind my washing machine that had rusted out badly around the lever and was leaking. The new valve was significantly cheaper than anywhere else. The valve is a perfect match for the Oatey version, however, the O-rings it comes with, like many reviewers have noted, are garbage. Don't even bother trying them. I got a bath when I tried using the supplied O-rings. Purchase some #11 and # 6 O-rings from Home Depot or your local hardware store and use those to replace the ones supplied. I did not have to open my wall and and simply seated the new valve on the existing plumbing connections (so I did not use the ones provided).
