I have a one-piece Kohler Rialto (3402) toilet that looks like it needs a new fill valve. It is leaking around the top. Looks like the unit is based on a Coast/Master 1Q1X, so I found a new rubber/valve assembly for the top, and that did not seem to repair it, at least not entirely. I see that Kohler sells a $102 rebuild kit for the toilet (K-84499), and indeed, last year I put one of those into another toilet I had that had a crack in the float valve. It worked, but before I go spend another $100, I was wondering if there were any alternatives.
Here's the Kohler web-site with documentation on the toilet:
What I was wondering, is if one of the Fluidmaster or Korky replacement valves would work? They're a heck of a lot cheaper, like $10.
For example, the Korky (Lavelle) Quietfill:
- Will they fit? (height mostly)
- Will they work properly? (mostly where does the rim pipe attach)
Any other suggestions?
