Install fluidmaster 747 fill valve kohler toilet

SOURCE: toilet tank fill valve sprays water towards lid

Hi bpmorr1,

It may be that the fill tube has come disconnected . It runs from the top of the fill valve to the overflow. The overflow is the tube that runs up the middle of the tank. The fill tube runs from the top of the fill valve to the top of the overflow tube. Kohler has a little clip that can sometimes come undone and cause spraying.


If that doesn't do it, turn the water off to the toilet and take off the tank lid. Partially open valve ( Slowly). Locate where spray is coming from. If it is in the area on top of the fill valve then yes, buy anew one. ( Fluidmaster )

Please rate this response and good luck, Phil

You need to replace the flapper and you will need to purchase one specifically for the Kohler toilet. I have the same toilet and tried using a generic flapper and from experiance, it didn't work until I bought the correct one and I'm a plumber! Have a great night.

Mine does that also, here's what I found.; I am on a well and occasionaly sand gets caught in the valve thingy... Take the tank lid off, turn the arm that attaches to the float assy. 1/4 turn towards the back of the tank and take it out. Rinse off the gasket and pin as well as inside the hole. Reassemble and it should solve your problem.

Sounds like your flapper is leaking causing the water in the tank to lower until it triggers the fill valve. Replace the flapper (they're cheap and wear out easily).

if the flappper isn't closing, there is no suction AKA a clog perhaps.
