Review on Kohler GP800820 Rite-Temp Pressure-Balancing Unit Cartridge, Single, Black - Enhanced for SEO by Fred Griffin

I am optimistic and give this cartridge 4 stars. I tried 2 old model pressure equalization cartridges and each only lasted 2-3 years before it became impossible to regulate the temperature and the knob became harder to turn. I've never had any of the leaks that others have reported (knock on wood). This cartridge installs just as easily or even easier than the old model and instantly fixes the temperature issue and seems to have more pressure. I really just hope this newer model lasts longer than the old model. I'm disappointed that the Kohler product doesn't last long, but grateful that it's not overly expensive or difficult to replace. I'm very glad I chose the valve model (which has this cartridge installed) with built-in water shutoffs so I never had to shut off the water throughout the house to replace the cartridge. I would like to point out that this cartridge does NOT come with the silicone lube that it should and was mentioned in the installation videos. Maybe it just wasn't in my box, but it was factory sealed and undamaged. Luckily I had the silicone grease used for pool o-rings on hand which should be the same and it worked great. Also, a helpful tip I've seen online is to use a paper plate under the valve when removing the front. to drain any water left in the valve or shower pipe so that it flows into the shower or bathtub instead of flowing down the wall. This worked great for me and not a single drop got into the wall cavity. I saw this suggestion on YouTube when I replaced the first valve and it worked great every time.
