Customers are satisfied with the performance of the valve. They mention that it works great, and has been working properly since it was installed. Some say that it also works great on older Kohler toilets.

76 customers mention49 positive27 negative

Customers are mixed about the quality of the valve. Some mention it's a quality replacement, while others say it has subpar quality control. Some say the rim of the plastic flush valve is flimsy and the fill valve is made of cheap materials. The flapper was not properly manufactured and had a small rubber nub on the flap.

"...I saw no damage or flaws to any of the pieces, so I am confident that this kit works perfectly fine in the newer version of the Kohler Rochelle..." Read more

"...Had it for 26 years, and the only problem was a weak flush for the last few months...." Read more

52 customers mention16 positive36 negative

Customers are mixed about the value of the valve. Some mention that it's great value, saving them a ton of money. However, others say that it is rather costly, requires maintenance at a purebred cost, and is more work than it is worth.

"...Cons:*Very expensive at $90!*UNNECESSARY (and again, expensive) bundling of filling valve and flush valve.*..." Read more

"...Yes, I appreciate the brass parts, but it's still expensive. So, the good news is that you get everything needed to fix your toilet...." Read more

"...This one fit and was cheaper to purchase. Can actually use toilet now!" Read more

45 customers mention23 positive22 negative

Customers are mixed about the fit of the valve. Some mention it fits perfectly, while others say it was poorly designed and didn't fit. The plastic drain tube wouldn't go into the hole inside of the tank, and the replacement flapper/flush tube assembly didn''t even fit if you have the original design. The bowl rim water feed didn'"t fit into the tank hole and was too tight to make it worth trying again.

"Perfect fit, quality parts. Exactly what we needed!" Read more

"...So, this kit did not fit my 1970's version...." Read more

"...The kit fit well and is a good price. Thanks." Read more

"...surprised when the flex hose for the bowl rim water feed did not fit into the tank hole (hose was too large)...." Read more

26 customers mention10 positive16 negative

Customers are mixed about the leakage of the valve. Some mention that it stopped their leak, while others say that it continued to leak. Some say that the top of the housing leaked, while other say that they can still hear the leak and hiss. Some customers also mention that the flapper assembly had been leaking, allowing water to trickle into the bowl.

"...One day the inlet valve let go and water was continually flowing, so a replacement was needed...." Read more

"...No leaks, no running, a perfect flush.. like new.Only four stars because:The rim hose should be shaped and easier to install...." Read more

"...but it just wasn't flushing and filling well anymore along with a small leak...." Read more

"...For my Rochelle, the fill valve is cocked a little bit, but the tank doesn't leak...." Read more

*Why I bought this?My 1995 San Raphael (K3397) toilet had a broken floating arm "hinge" or joint that was plastic and part of a non-Kohler fill valve kit from years ago (no longer sold). Everything else had been working just fine. In an ideal world I'd only need to replace this hinge rather than filling landfills with even more plastic. Anyway I did end up looking into replacing the entire fill valve set with a more modern kit (e.g. Fluidmaster 400A). Only potential (and probably solvable) problem was compatibility with Kohler's rim feed inlet. This uncertainty led me to go back to Kohler, again.*Did this kit solve my problem?Yes, for now, but at cost. I am left with parts I never needed thanks to Kohler's bundling of flush valve parts. I also think naming this a "conversion" kit is misleading: there is no conversion whatsoever. It is just a replacement kit of the same old ball-cock design albeit with Kohler's modifications. It is not an improvement over the original, nor does it convert the old design into anything else.*Was it easy to install?Yes, just follow the official video or read the booklet that came with it. The most difficult part for me was finding an adapter for my water supply pipe, which here in Taiwan is 1/2 inch rather than 5/8 of an inch.*Will I buy this again?No. I'd replace this 26-year-old Kohler with a modern non-Kohler designed with universal parts.Pros:*Did solve the problem by replacing the broken floating arm plastic "hinge".*Some parts are now metallic and less likely to break.Cons:*Very expensive at $90!*UNNECESSARY (and again, expensive) bundling of filling valve and flush valve.*Subpar quality control, namely the plastic flush valve "rim" (see photo).*Subpar packaging: all the parts thrown into a box with plenty of space to roll around, only the shank/valve part and the (here we go again) unnecessary flapper kit received any padding.So far so good, will update if things go south.
