Question: A reviewer complained that this is actually a Fluidmaster 400A.  Is that what you got or was that reviewer ripped off?
Document: I've noticed some comments stating that this is identical to a Fluidmaster 400A. It's mostly a Fluidmaster 400A in its parts, but has some components that Fluidmaster specifically makes for Kohler. Not sure if they're absolutely critical, and I'd be surprised if a standard 400A didn't work. As long as the height can be properly adjusted and the threading fits, this part is going to be interchangeable.I got this one to replace the original part in a Kohler Rosario.
The gaskets for a hardline water supply are different. Almost everyone has a flex line these days - so the parts for a hardline connection are almost always throw-aways. But...Kholer gives you a flat washer for hardline. It's got a fiber layer in the middle.Fluidmaster gives you a cone washerThey should each provide both, but they don't.At the end of the day, I would just get the Fluidmaster 400A and save the five bucks; you're getting the same exact thing.
This part comes from Kholer but it's a Fluidmaster part. I've called Kholer about other parts that I've ordered as Kholer parts which arrived as Fluidmaster and they told me that Fluidmaster makes some of their original parts. This valve is exactly the same as a Fluidmaster 400A, in fact the Fluidmaster name and part number are molded into the part. They did make a different cap for the top of the valve so that something would have the Kholer name molded into it.
Maybe I just got lucky as this universal fill valve worked fine for my Kohler toilet.
Slightly more expensive than the FluidMaster equivalent, but given the frequency of replacing this part, I didn't mind spending a few bucks more (to have the confidence in the OEM part).
JUST INSTALLED LAST WEEKEND, FIT PERFECTLY, EASY TO ADJUST, EXACT REPLACEMENT, ALL PARTS NEEDED WERE INCLUDED. PURCHASED A SPARE FOR OTHER TOILETS.
We could have replaced the horribly wasteful (3.5 GPF!!!) Kohler Rialto several times over with the expense of leaking water and replacement parts. Frustrated with the Korky valve that wouldn't shut off (and merely 6 months old, and yes, dissembled & cleaned multiple times, but 2-3 flushes later it was hissing again) I got the Kohler parts and VOILA! 10 minutes in and it's not leaking!!! Yay! I hope I don't have to post an update in 6 months.
Don't hesitate to order this if you have a leaky toilet. I purchased a universal valve from a local hardware store and for months I could not figure out why my toilets would run periodically. My water bill went up and I couldn't figure out what was happening. I finally got the model # from the lid of my toilets and ordered this item, I had both toilets fixed within a hr. Just wished I had ordered this sooner. I could have stopped worrying. The seller shipped the items fast.
I should also note, that while the Fluidmaster 400 looks almost identical--it is not. The parts are clearly higher quality (including the piece that attaches the fill valve to the toilet). I don't know if other comments about Fluidmaster making the Kohler are correct, but even if they are, Fluidmaster clearly decided to make a better version for Kohler. Don't waste your money on a Fluidmaster--go with this one.
I paid $10.99 for the Fluidmaster part and the same thing in a Kholer blister pack was about $17.There are some differences in what you get, and it's those differences that make all the difference.1. The directions that come with the Kholer part are almost useless. The directions that come with the Fluidmaster part are very good. Probably the most pertinent thing to understand is how to adjust the length of the valve. The Kholer directions are silent on this.
Answer: yes
