It was very easy to install and it worked as advertised!

The cheap ones have cheap rubber gaskets in them that disintegrate in just a month... buy this genuine OEM one, it is well work the few extra dollars!

I highly recommend getting this whenever you replace the mixer valve.

I was troubleshooting an issue with a shower faucet not properly dispensing hot water. I had replaced this cartridge in two other faucets (to solve leaking issues) so I figured it was either this part or the mixer valve.

Turns out, the mixer valve was the guilty party for this issue, so I'm keeping this part as a spare -- I'm sure I'll need it again in the future.

For those wondering, this DOES come with the replacement O-rings and a directions sheet.

From an installation difficulty standpoint, I'd peg this one at a 4 / 10. If you are even somewhat handy around the house, you can do this. Just make sure you shut the water off before you start :-)

One reviewer gave this product 2 stars because it didn't stop his leaking. Keep in mind the mixer valve assembly, missing/wrong O-rings and faulty plumbing can also cause leaks with a faucet using this part. Outside of replacing the whole assembly (including the brass body) starting with this part is a good move.

This is just what I needed when the shower would leak when OTHER hot water devices were turned on in the house. Direct replacement, and solved the problem. We had already replaced the front end seals for on-off, but that didn't stop the leak when the hot water pressure dropped in the house.

Disappointed with Kohler that the original PBU failed after only 2 years. This new one works fine, but I'm thinking of buying some spares, in case they're not available anymore a few years from now. (Kohler has re-designed this whole unit and future replacements will be more in the $300 range and require a plumber.) This kit came with extra o-rings and spacers and difficult instructions, but I was able to figure out which ones to use and which ones to ignore by carefully examining the defective PBU as I removed it. I would definitely order via "showerdoordirect" thru Amazon again. Fair price. Reliable shipping.

My shower faucet was either all hot, or all cold. Once I replaced this part, BINGO!, hot showers again! It was an easy fix, took about 10 minutes.

👍Waterproof seal. Came with the small rubber gasket/washers to keep a tight seal
👍Fixed problem where I was not getting any hot water
👌
👎Expensive (my opinion)

TIP: If you're replacing an existing unit, be sure you remove the rubber washers if they get stuck in the wall.

I replaced the original Kohler PBU with this new one since the control lever had no effect on hold/cold water temperature. This quick and easy fix solved the problem and the old unit was calcified, frozen, and the rubber diaphragm in it was deteriorated. The unit came with instructions, extra rubber gaskets, and washers. It was easy to install for a do-it-yourselfer. This simple fix should save you a bundle vs calling a plumber.

Cured a leak on a 15 year old shower so it saved a plumber call. Nice to be able to buy parts for old Kohler fittings.

We had a slow leak in the shower. I replaced the old pressure balancing unit with this one and the leak was gone. Make sure you install the unit the right side up.
