Kohler toilet not filling up with water - Kohler Toilet - One Piece with Ingenium Flushing System - San Raphael by

Valve fully open on inlet going into toilet if it is then fill valve needs to be replaced check water line for any abstructions that might interfere with water going into tank.

Hi!please kindly check your fill valve if it is working correctly.I thought the problem is in your fill valve.Kindly adjust the floater of your fill valve.

the tube that goes from the fill valve to the fill tube may not be installed correctly. the water must be going in the tube and not the tank. also it is a water conserving toilet so it uses less water also it is a comfort height toilet and to make it taller the bowl is extended so the water may seem even more shallow.

There is a screen @ the inlet to the vavle where the water connects that may be plugged or contact Kohler they will send you a repair kit for the fill valve.

There is a volume control screw on the valves usually a plastic thumbscrew on side of valve turn clockwise until they quiet up the plumber should have adjusted that these are very tempermental toilets but when adjusted properly are excellent toilets I have 2 in my own home

I had exactly the same problem. Just turn down the water pressure @ the valve on the water inlet line. While you have the toilet lid off, you may want to remove the fill valve (1/2 turn counterclockwise on the plastic nut attached to the water-in line), and clean the rubber diaphrams (there are 2). They will sometimes get gritty and this will cause some fill noises and leaking.

Hi
try to increase the amount of water for each flush .

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).

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.

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
