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

My faucet cover failed and I decided to replace this part as well. I've seen some people say it has a constant leak. I could live with a leak, but my pressure built up and at just the right moment, around the middle of the night, a steady flow of water began with a high-pitched noise. Also, I didn't know that there was a valve behind the outerwear in the closet in the hallway to shut off the water. I got up several times at 1 (different times) in the morning, went outside in the cold and turned off the line in the yard. I went back and took apart the shower handle and just reinstalled the part and everything was fine for about two weeks and here it is again. I ended up calling a plumber and he showed me where this part had mostly sockets and the old part had plugs. In short, make sure this is connected to your pipes before you buy.
