Kohler Canister Valve Unseats

[Corey Hammer]

Upon even the gentlest of flushes, the canister valve on a Kohler toilet that came with our house when we bought unseats itself. Consistently. How do I fix this?

Sometimes the canister catches on the fill tube if it's too close. I've installed a longer fill tube if that's the case. Any tube from a Fluidmaster fill valve will work.

Would that pull the whole assembly out? Even the anchor comes out...

If the anchor is coming out, it's not turned in to hold it. The center core rotates so that it can be removed for the seal replacement, and then reinstalled.
