Default Canister style toilet flush valve help.

I have a friend that was asking about having trouble with his toilet not flushing good anymore. I asked if it did not drain right or what the problem is. He says he has to hold down the handle for it to flush properly and that is is a mayfair toilet from Menards. It has one of those kohler canister style flush valves and not the regular flapper. I'm wondering if anyone here has some knowledge about why you have to hold down the handle for it to flush? I'm thinking it might be the water level that needs adjustment or maybe the handle chain but I have not yet had a chance to check it out.

Could be a loose handle, the chain on the canister is so short there’s usually no room for error of someone not adjusting it correctly.

Bring a new canister seal, the original red ones are usually gummed up and sticking all over the flush valve seat. The new chlorine resistant ones are yellow.

Thanks I know what you are saying about their old red and new yellow ones. I actually ended up having time to go over there tonight and just came back. It ended up being some older box store thing and not a kohler style. He already had a bunch of new parts for it and we ended up replacing the tube (smaller canister thing) and I have no clue why but it worked. The old one dropped down too early and did not let a full flush through.

Better off to replace the entire canister rather than just the seal,they not expensive but can be hard to find

I carry the post and the seal but not the canister. The tabs on the bottom of the post sometimes break and the bowl fill tube jumps out on the old style posts. They made improvements on the design of the new posts.
