Can I clean my Kohler 1068030 Fill Valve

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.

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).

Check the fill tube in your toilet one easy way to see if it's leaking is get food coloring and pour in your tank to color the water this makes it easier to see and squeeze the tube in the tank when it's full if you see the colored water running down the middle of it you have a winner! if not you can look around for it sometimes the plastic under the flapper gets cracked too

check the fill tube. sometimes they crack, put some food coloring in the tank and that will help you find leaks too. gently squeeze the tube and see if you see water running down the inside of the tube
