## Questions & Answers

**Q: Ordered this part after plumber reccomendation.  It fixed our leak in November of 2021 and is now leaking again.  Trying to replace for new one.**
A: I had the same issue. It worked for a month. I bought another and the same thing happened. I eventually bought the Kohler replacement part (new design - it doesn't look like the old part) and no leaks. You get what you pay for.

## Customer Reviews

### ⭐⭐⭐⭐⭐ It works. Just remember to apply silicone grease to the O-rings.
*by  on Reviewed in the United States September 27, 2025*

It drips at first. I reinstalled it and applied silicone grease to the O-rings this time. No dripping so far. I recommend that the manufacturer includes a small capsule of silicone grease in the package so that people don't have to buy it separately. I guess some of the leaking/dripping reviews were because no silicone grease applied to the O-rings.

### ⭐⭐⭐⭐⭐ It was the exact fit for my old Kohler
*by  on Reviewed in the United States April 11, 2024*

As others have said, this is apparently the older style, which is what I actually needed for my nearly 20 year old shower.I don't see any leaking, and the knob now operates smoothly and precisely (as precise as a shower knob could be, I suppose).Ask me in 10 years if it's reliable. :D Actually, it'll probably be fine. It seemed to be as good as the original one was in terms of quality. Buying an original isn't really an option, since it's obsolete and only available from people with old stock who overcharge. I decided to take my chances on a new aftermarket part, and it paid off.I would recommend it.For anybody who is curious, I didn't have any leaking, and it did get hot and cold. The symptom was that the knob didn't turn as well (I didn't realize until I replaced it), and it was very difficult to get the temperature right. I would have to turn it all the way to the stop to get it hot, then turn it almost all the way back down to get it to a normal temperature. It was slowly getting worse over time, but got significantly worse a couple of weeks ago, which is what prompted me to look for a replacement. I wasn't sure if it was the valve or the PDU, so I did both.This part came with extra washers, so I picked the ones that matched the original (the smaller ones). It also came with a little wrench for adjusting the temperature stop. They also threw in a couple of squares of sandpaper, just in case, but I didn't do anything with the sandpaper.I did put some o-ring lube (from my swimming pool stuff) on the rubber washers, just in case. If nothing else, it helped hold them in place until I had everything back together.I was very happy that I didn't have to tear up the walls to get this job done.

### ⭐ Not worth the cheaper price
*by  on Reviewed in the United States January 24, 2026*

Worked great for about 11 months then started to leak, which basically means the design sucks if it can't last a year on a tub that get's used about twice a month. Original Kohler unit lasted 12 years. No service help available so guess i'm buying a new one, not this brand.
