Rated 4.7 out of 5 by 26 reviewers.
Rated 4.0 out of 5.0 by Replacement Part Works Okay Although the O-rings on this replacement part aren't seated as well as the OEM part it worked okay to stop the shower head leak. The OEM part lasted 14 years but I doubt this replacement lasts that long. This was my first DIY project on a shower cartridge. Installation really requires that you coat all the O-rings on the cartridge assembly with silicon grease so you get a good tight fit that won't leak. So when you get this part get some Oatey or Danco silicone grease 'cause you're going to need it. June 8, 2014
Rated 4.0 out of 5.0 by Easy to install... The product was easy to install. I would advise anyone buying this product to view the video by DeltaFaucets on YouTube for instructions regarding which cartridge model to replace. It is much clearer than anything they present on the actual Delta website. Home Depot, it was a pleasant experience ordering online. June 10, 2014
Rated 5.0 out of 5.0 by Easy No issues with installing this replacement valve. Getting the old one out was a challenge. Be prepared to use a penetrating spray to help loosen up the old part. Once it is removed, the new goes in and you are back in business in a few minutes. January 15, 2015
Rated 5.0 out of 5.0 by Delta Cartride Assembly My home has plumbing over 12 years old. It was very difficult removing the old part. The new part eventually was installed and performed as expected. December 17, 2014
Rated 4.0 out of 5.0 by Cartridge Seems a bit pricey for a cartridge, but it worked. November 4, 2014
