You can use a 2" flapper flush valve to replace the canister. I keep two 2" flapper flush valves on the van. We are a Kohler dealer and have sold thousands of these toilets, but I have had no need to carry the canisters on the van as of yet. Maybe in 5 or 10 more years. I've only had two locations need new flush cans due to breakage. One has extremely acidic water and the other was broken by a Grandchild.Good to know. Problem is: it was a yellow one.
I guess I could have replaced the canister, but it was a Sunday and I needed to get it done.
So, here’s the question, do you all keep a canister on the truck?
IMO the business cost of the job goes way up if I have to go to the supply house in the middle of a small job like this one. And you can’t really charge more -I guess you can; but you’ve got to bury it somewhere.
I don’t do a lot of service, but I most certainly keep a stock of parts around for stuff like this.
I did have one house with terrible water, the canister didn't break but would constantly get mineral buildup, I swapped that out for a 2" flapper flush valve.
I also keep one or two 3" flapper flush valves on the van. Frankly a simple, single flapper assembly seems to be the best mechanism, whether that's 2" or 3".
