I have a tenant who complained about a running toilet. I opened the toilet tank lid and noticed the white tubing coming from the fill valve was NOT inserted into the middle of the flush valve.





So I inserted the tube back into the middle of the canister flush valve and everything seems to work now and the water is not running after I test flushed half a dozen times.



Any idea how this tubing could have worked itself loose like that? Or the tenant messed with it and didn't know what they were doing?

An unrelated question, if this flush valve ever breaks, do I have to replace it with a genuine Kohler canister flush valve, or can I replace it with a generic flush valve with a flapper/chain?

Best practice is stay with Manufacturer parts. Period. But to answer your question, water under pressure will tend to lift the tubing because of the curve in the tubing. Also I have made many trips to the hardware store trying to fix a leak inside the toilet because the flapper was not the correct one to fit the flush valve with a proper seal. That is my reason for staying with the manufacturers parts

sorry should have been K-4634 not K-4624.

Is this true for everything though?

I tend to replace a broken fill valve with a FluidMaster ones as it seems to be they work better and are more quiet, even when the original manufacturer fill valve is available. I toss out the manufacturer's tank and floor bolt kits all the time when I am not sure if it's SS or plated and use my own that I purchase at the supply store.

This canister style flush valve doesn't seem as simple as the standard flapper type. I am curious if I can use a standard flush valve in it's place, not that I will do it, just to know if that option is available. Seems like it should, unless the big hole at the bottom of the tank is non-standard diameter, or the vertical distance between the bottom of tank to the inlet to the bowl is non-standard, then it won't. Seems this canister style valve is not as serviceable.

the water level is too high

adjust the float on the fill valve down 1/2"

Very few manufacturers make their own parts. Most Kohler toilets use Fluidmaster fill valves and Korky flappers, while Toto uses Korky valves. Unless their is some overriding reason not to, I use generic replacement parts. I have not worked on one, but the canister may be a bayonet mounting, and if so, it would be easier to replace/repair than changing to a different style.

sum, you can change the flush valve to a conventional flapper type.
you would have to remove the tank to do this.
you will then (more than likely) need an adjustable flapper to get the correct flush ??
probably something like this..
