Toilet Help

taylorgeo

Hey all,

Kohler toilet is only 3 months old and the fill valve started refilling on its own approximately every 15 minutes. Lasts around 10 seconds. Don’t really want to call a plumber for this if I don’t have to. See attached picture. 

Thanks!

Is the tank water leaking into the bowl through the 1.) flap OR through the 2.) overflow? If: 1.) make sure flap is sealing. Your chain looks kind of bound-up. 2.) lower the water fill-level in the tank using the gray stem with "cross" on top. Water level should be just below the top of the overflow.

  The gasket on the bottom of the flush tower may not hold up well to high concentrations of chlorine. The same is true for the flush valve gasket.
   Kohler tech support is extremely user friendly and will sometimes ship repair parts at no charge to the original owner. They'll also give repair advice based on symptoms.

Another possibility is the seal under the red cap on the fill valve. I have to change mine about every six months. Fluidmaster part number "PRO22". About $2. Worth a shot.

I had a similar problem with mine and it turned out to be due to minerals on the red gasket at the bottom of the flush valve.  It is easy to remove and clean.

My bet would be on the twisted chain that is knotting up holding just a little bit of tension on the flush valve so it is leaking. Where is the water level marked, that looks a little high too but I don't think that is your problem.

When you flush it, and it refills and shuts off, how close to the top of the "flush cylinder" is it? Does it shut off and then creep higher and higher?

If you shine a flash light down into the cylinder, can you see water dribbling down somewhere near the bottom? is it overflowing over the top of the cylinder?

Is that sand / dirt in the bottom of the tank, if so, why? Grit destroys valves over time.

If that is dirt/sand in the bottom of the tank then it got in there thru the fill valve.

I believe you are supposed to flush the fill valve when installing.

Shut off the water, then push down on the float ( or maybe lift up, can't recall) , and untwist the top.

Small container or hand over the top and open supply to flush.

You can see the top seal in the cap. Maybe clean it.

Yes the chain should have slack in it.

The flapper and seat must be clean.

Check the adjustment of the float.

I think all the bases are covered now.

Just saw this one. It reminded me of a day last week when I was stranded on the bowl with no roll.

That is when you REALLY need Toilet Help

Thanks for the help, all!

Kohler sent a free gasket, and the problem stopped without installing the new gasket.

Ghost in the tank?

I think it was the tangled chain.
