Any non Coast Replacement Fill Valves work in Kohler Rialto K-3402?
The Coast 1B1X float valves were OK, in their day, but I'm kind of wondering if any of the more recent design fill valves can work in a Kohler Rialto K-3402 (pre-1998):
Here's the toilet specifics:
The Float Ball is actually a fairly tight fit near the Flush Valve assembly, I worry a bit if the flapper is going to clear, and if the Ball is going to hit the side of the tank, etc. I noticed that Kohler in the evolution of the Rialto has used some non-ball designs, one looks like a Fluidmaster. And I seem to remember Fluidmaster at one time making a 1-piece tank replacement (doesn't seem to be obvious if they still have that).
But the part I cannot figure out, if I were to use one of the newer/cheaper fill/float valves, is how to do the diverter for the rim that Kohler has. This is a 2ndary float and valve type arrangement, big plastic tube, that comes out of the Coast 1B1X just under the top.
New Part Number for Kohler 3402
I just replaced the ball cock flush assembly with new parts from Ace Hardware. It no longer part number 1B1X but is now part number 04-4165. State replacement for one piece toilets.
Comes with the tubing and the bar for the ball. Good to go and only $24.39 before tax.
Brass Replacement Valve Assembly for Rialto 3402
I have 4 Rialto 3402's and had constant problems with original Kohler plastic valves, I replaced them with the Coast copper /w plastic sleeve valves but these also started to leak after about 3 years and I could no longer find replacements or parts at my local supply house. About 4 years ago I got tired of the cost and hassle of having to repair/replace the valves on a regular basis and had decided to replace the toilets when I heard about a small company who was starting to market solid brass replacement valves for the 3402. The valves were perfect replacements and significantly better than the originals.
I recently experienced a very strange problem with the valves starting to leak a few hours after shutting off. I called the company and after trying a few of their suggestions, they replaced the valves. Working with this company is an incredibly satisfying experience. They make an excellent product and stand behind it. A very rare trait nowadays.
I wanted to recommend them to anyone looking to replace/repair the Rialto 3402 valves. Good luck
