My K3489 toilet leaks down and refills every few minutes. I replaced the flapper with a factory replacement with no affect. The leak seems to be around the 83996 soft rubber gasket at the bottom of the...

Hello, W/D here.

With the water off, drain the tank (lift the flapper). Look inside where the flapper seats. If the (usually black) gasket is rippled, this may be the cause of your trouble. You can remove the rippled portion of the gasket with a razor knife, just be very careful not to damage the flapper seat. Removing the protruding material will allow the flapper to fully seat without damaging the gasket integrity.
Best regards,

I have a K4632-AA which usually works just fine but now it has started to run water every few minutes. What might be the probelm and how can I fix it?

Toilets seem to run on their own because the water in the tank is seeping our past the seal that was designed to keep it in the tank inbetween flushes. Commonly called flappers, they go by seals, tank balls discs. etc. The K4632 requires a flat seal from Kohler. The actual part number is 1059291, however Kohler may only sell this as part of a kit by a different number with pieces not truely needed in your circumstance.

You should contact them at 1-800-4KOHLER, navigate the prompts, and talk to a service member. You may have to do some research in your area to find a retail or wholesale business that will order this for you. There are circumstances where, with some parts, Kohler will send the parts free to your doorstep. No promises on this one. I have put a link below that will give you a complete parts explosion for your reference.

Runs for 6 seconds every 35 min. flap replaced.

Sounds like your flapper or flush gasket may need to be replaced. An easy way to check this is , the next time you hear it kick on, wait for it to stop and put a couple drops of food coloring in the tank and wait about twenty minutes and see if there is any color in the bowl. If there is then replace the worn flapper or washer. Hope this helps.

What is the procedure for replacing the flush valve assy on a san raphael toilet. it is a one piece tank and bowl assy and must install from the inside of the tank. it appears to possibly rotate into place...

If you purchase the flush valve from Kohler, it comes without instruction. Rotation is the key to removal. First note the exact orientation of the assembly before attempting removal. Unhook the flapper chain and remove the flapper. The old assembly does indeed rotate in either direction for removal. I used a counterclockwise motion. (it was a tough turn, don't break the bottom of the bowl where the valve seat is located.) Then install the new foam gasket on the assembly. The new assembly is replaced in the reverse manner. I removed the new flapper from the flush valve for ease of install. You must put significant downward pressure on the flapper seat while rotation is accomplished. Orient the assembly as was the old one. Replace the flapper, connect the chain and observe the flapper for proper opperation.

Not the float

Had a similar problem with a Wellworth after changing out all the replaceable parts. The new triangle gasket + nut kit was missing the flat anti-friction ring needed to allow the plastic nut to be hand tightened enough against the rubber gasket - without the ring the friction stops the nut turning, and you get a leak because there isn't enough pressure on the gasket. Retrieved the old ring from the trash & put it in - works perfect now! not sure if this is your problem too, but you might want to check the locknut / gasket tightness & seal.
