Great replacement valve at a fair price.

Would Recommend

This valve was an exact replacement for my original delta valve. It came with everything needed for a successful replacement. Once installed you can easily set your temperature preferences. The valve works great.

Easy install

Would Recommend

Had a hard time removing the old one due to hard water buildup, this one went in very easy, and lined up first try. It’s been working great for the past few weeks with no issues at all

Works but salty

Would Recommend

Fixes the dripping problem, but way too expensive. Had to replace in two showers so there went $150. Not only that, the last one I replaced lasted less than 3 years.

Works but costs more than other designs.

Would Recommend

This item fit and worked perfectly as a replacement to the original part. Older shower valves and other faucets often have replacement parts like rubber seals, and springs that are much less expensive and replaceable at a much lower cost with the same amount of work.

Would not recommend.

Would Not Recommend

Starts to leak every 3 to 6 months. Replaced the O-rings and the cartridge twice. Last time I replaced the cartridge was November 2024. Correction, that is when I ordered it. Didn't arrive for 3 more weeks. It was a constant stream of water. I had to shut the water off to my shower after every use. The worst part is it's not even a good shower. The water pressure for the shower is weak.70% is plastic. Would not recommend.

Don’t buy the knock off

The cartridge worked with no leaks unlike the knock off I tried.

Finally!

Would Recommend

After trying several imitation cartridges to save money, the shower handle felt flimsy, and the water never seemed to get hot enough, even when sent to maximum.. After two tries, I finally broke down and bought the Delta OEM part. The shower is working like brand new again! It pays to go with the original replacement even if it costs more. Also, I had a very difficult time removing the cheaper cartridge because it broke in pieces when trying to extract it. Lesson learned.
