    Hey everyone!

    I'm a first time home buyer and I'm trying to learn how to do things around the house. Pardon my ignorance!

    I have a Kohler toilet with a canister flush valve. When I flush the toilet the canister occasionally (50%) sticks at the top and doesn't drop. This results in the water running. I have to lift the toilet tank lid and tap the canister and then it falls and the water stops running.

    I have googled this and shockingly no one talks about it. There are countless videos about replacing the gasket but nothing about the sticking problem. To be clear, the water runs bc the canister doesn't fall back down after flushing. There's no issue once it's back down. So I don't think it's a gasket issue. I cleaned the gasket and there was no build up either so I don't think that's why it's sticking.

    Any help would be greatly appreciated!

    Thanks in advance.
