Review: Great kit, a few installation nuances - I can’t speak to the longevity, only the installation, which was great. I have no idea which model my old shower valve was, nor whether I really needed the pressure balancing unit or the mixing valve, so I replaced both with this kit. I just knew my old valve was Kohler and I couldn’t get very hot water from the tub spout, and the water temp was kind of bouncing around. The PBU on this kit looks a little different than my old one, with a slightly different shape and the new one has oval rear holes vs round. I did some research and found this was all normal and by design. Mine had a white threaded tube that goes on the outside of the valve (for the handle to screw onto). I had to search forums to learn that this snaps off with a little pressure from a flathead screwdriver from the bottom. Then it push-snaps onto the new valve. All in all, straightforward installation without any hitches. Works great, no problems. Consistent water temp, hot is back, and no leaks when off.
Review: Perfect! - Great qualtiy, easy to install! Worked perfectly! I will buy same thing for my other bathroom.

## Questions & Answers

**Q: what comes in the box? O rings? lube?**
A: Yes, o-rings and really small tube of lube. But I purchased a separate tube of Danco silicone grease to have at hand.

**Q: What is the part number for the servicing kit with the o-ring?  One poster said it comes with the kit.  The video doesn't?**
A: The valve with the o-rings and small tube of silicone gel is all one item, part number GB876851.

**Q: I have a kohler forte and it's leaking. should i get this newer model or the previous model gp76851 mixer & pbu sp kit?**
A: Depends how old you valve is. If it is older you should get the gp76851

**Q: What are the flow specifications?**
A: Not sure. If you have the kohler 304 valve this is the cartridge for that valve. Its cartridge and balancing spool. Its comes in 2 parts. You can google it and they might be able to tell you the specifications

### ⭐⭐⭐⭐⭐ Perfect!
*by G***7 on January 5, 2026*

Great qualtiy, easy to install! Worked perfectly! I will buy same thing for my other bathroom.

### ⭐⭐⭐⭐⭐ Great replacement - solved my cold water running hot
*by E***E on August 26, 2025*

My cold water would run hot. I had 3 things in our home that potentially had cold-hot water mixers - the kitchen faucet, the shower and the clothes washer. I was able to test the clothes washer just by checking the water while it was filling and switching the temperature - it was fine. Also, I don't think the type of valve I had in the clothes washer was actually a mixer that could cause my cold water to run hot. I noticed that cold water in the shower (and the sink in the same bathroom) would run hot long before my kitchen faucet so figured it was my shower pressure balancing valve. I had a 25+ year old valve and it looked different from the new one, but thankfully the Kohler stuff seems pretty standardized so everything fit and worked well. I watched videos to figure out how to replace. It was a very easy DIY.
