Question about Kohler Home
After unclogging toilet, the bowl does not refill completely then drains down to 1/4 normal fill level
It is possible that the vent pipe behind the toilet is clogged (or was not installed properly). Some bathrooms are set up with one shared vent pipe, and a clog in one of the lines leading to it can cause similar problems.
The vent pipe in each bathroom does 2 things:
1: it lets the sewer gas go past the bathroom and up out the roof so you don't get sewer gas in the house.
2: It breaks the siphon as water goes from fixtures down to the big sewer pipes in the house. If it isn't working for a sink, it's not much of a problem because air gets mixed in with the water as it does down the sink, and this breaks the siphon. But in a toilet, it jsut keeps pulling water down the pipe until the water level in the toilet gets low enough to let air into the pipe, breaking the siphon.
It's not an easy problem to fix and often involves removing walls to get at pipes.
A plumber can bring a snake tool and try clearing the pipes from below or from the roof, and might even be able to bring a steerable snake that lets him control how it goes through the pipe.

The tank holding the proper amount of water is a good sign. The inside of the stool is like the GOOSE NECK under you sink. It always holds water. This may sound like a bit of a hassle to do but if all 3 toilets are identical, here is what you can try if you are a bit handy. Go to the hardware store and purchase 4 toilet wax rings with a plastic flange and a few sets of toilet floor flange bolts(they are cheap and you can always return if not used, as It is better to have xtra parts on hand). Turn off the water supply to the "Mystery Toilet". Leave the tank and everything connected to the stool. Flush the toilet and remove all excess water from the tank and bowl. This can be done with a shop vac, sponge or towel. Disconnect the water supply to the tank. Remove the bolts holding the stool to the floor and carefully remove toilet. Scrap off all the old wax from the floor flange and bottom of stool. Now go and repeat this proceedure to one of the toilets that is working properly. In other words Switch the "Mystery Toilet" with a "Working Toilet" and see how they react. If the working toilet does it in the same bathroom and the "Mystery Toilet" does not do it in the other bathroom then you probably have a VENTING PROBLEM. If the "Mysery Toilet" Does it in the other bathroom then you most likely have a Defective Toilet. This Job is best done by 2 people, as it can sometimes be challenging to center the new wax ring on the toilet flange. Reconnect to the floor and reconnect water supply to the tanks. DO NOT OVERTIGHTEN BOLTS to the floor flange as you may crack the toilet. All drain lines must be vented properly for water to flow. If you are curious check out drain venting on the internet. Also, sometimes a vent can become obstructed with debris, ice, bird nest, etc.. I would 1st check the vent on the roof visually and then have someone flush and listen. If you believe the vent is clear....Then do the toilet switch and go from there.....Hope this helps and Happy Holidays....Joe

I have minute amount of leakage into the bowl causing mold to grow. I believe that it may be the rubber seal for the flapper body to the porcelain.

First, fyi, adjusting the knob? in the tank, or the fill level will not increase the amount of water in the bowl. The bowl fills to a certain point, and then as more water is added it starts to go over the built in trap, and down the drain. When you flush the toilet, all the water in the tank dumps into the bowl, and the existing water is pushed over the trap and down the drain. All of this being said it sounds like you may either have an internal crack, between the bowl and trap; you may have a crack that is draining under your toilet, (water spots?), or you have a more serious plumbing issue, improper venting, which is causing a vacuum, and pulling the water out. Hope this helps.

put some water in with a bucket. poor some in slowly until you get it where you think it should have been. If it levels back out at the lower level. Then there is nothing wrong. Maybe the leaking water was keeping the bowl water line high than it should have been.

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
