Kohler Rialto K-3402 toilet fill valve repair
I found the forum doing some research on my cranky Kohler 3402PB. Couple of questions if you don't mind.
I can't seem to find much reference to the 3402PB model, only the 3402. Is it normally just referred to as the 3402, or do I have some other variant?
I am rather shocked to find that Kohler is almost entirely unavailable as an aftermarket parts pruchase. It would appear that the rubber plunger inside the fill valve has deteriorated, and is causing a faint but perceptible continuous fill noise. Is it possible to find this plunger by itself, or am I really stuck paying $80-90 for a whole new assembly.
If not, I'm seriously considering taking a shot at replacing the entire toilet with a new one. Appears to be rather straightforward as a one piece unit. For someone only moderately mechanically inclined, any tips.
Thanks, great site too!
I have 4 of the exact same Toilets
I am trying to sell them, any one know what they are worth. I have also heard them refered to as continuous flush toilets. Whats the deal with them?
Less expensive valves work better for me
Two of the K3402 (1983, 1985) were in the house when I bought it. Both fill valves sprayed at the top (and through the holes in the back of the tank). I bought a Kohler repair kit (about $90). It sprayed from the top. I have replaced the Kohler fill valves with Fluidmaster #400A and the expensive Kohler flappers with Korky. I run plastic tubing through a rubber stopper inserted into larger tubing inserted for the rim wash. Works fine.
I have a Korky #528 fill valve in a Case kidney side handle (1926) that also works well and I would think it might serve as well as or better than the Fluidmaster #400A in the Kohler 3402.
It has occurred to me that it is possible that occasional high pressure (110psi) from hot water heating contributed to the Kohler fill valve spray. I don't have an expansion tank (yet).
Thanks for sharing your sleuth work with the techs. Interesting.
I have Kohler on a list with Moen.
