The flush valve or actuator with the disc type of flapper just stays up doing a balanceing act after the flush. It doesn't drop down to allow the tank to fill.

This problem started after I replaced the red disc with a black one. Maybe the red discs are heavier and will make the flap drop down.

SOURCE: Toilet Refills Every 15-Minutes

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.

SOURCE: Toilet will not fill up

Some Toto fill valves have a plastic debris screen located at the inlet connection. Turn off the supply valve and remove the supply connection at the bottom of the tank. Use a mirror to inspect the screen for debris.
I agree w/ Smithbrother, the Fluidmaster fill valves are cheap and work well. The only thing they ever need is an occasional seal for $1.50 and 5 minutes to replace.

SOURCE: valve adjustment

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.

SOURCE: toto toilet, flapper doesn't stay up long enough to flush

One of two things is the problem. First, make sure that you have a tight chain with little slack. If there's too much slack, the flapper won't catch in the passing air to stay up. Second, the flapper is not correct for that style of toilet. You might want to look into purchasing a new Kolby filter that has a removeable cone in the center. Move that cone to 12 o'clock to allow the maximum amount of water to run through the flush valve. If the flapper you have now is flat, it needs to have a cone in the center on the underside.

When we flush the toilet, water continues to flow through a small tube into a vertical tube that is next to the flange, I think that's what it's called the part that lifts up by a chain when you flush
conventional flush: push lever, chain lifts "flapper" over the hole to allow water to enter bowl. As water goes down in tank, flapper covers the hole to allow the tank to refill. The small tube that dumps water into the standup, larger tube is what fills the bowl back up. Otherwise it would stay in a low water position allowing sewer odors into the structure. If the water does not stop, your fill valve is not shutting off. Probably needs an adjustment. If adjustment does not fix, replay flush valve.

How to adjust a toilet
  • Your toilet tank may simply need a good "tune-up." Here are some adjustments you can make.

  • Refill valve. If your tank has a conventional ballcock refill valve, the water level is adjusted by bending the float arm. The level should be high enough for complete flushes, but the water should not be to the top of the overflow pipe. Your tank should have a colored or molded water level mark. It should never be set so low that the bowl does not refill with trap sealing water. The rule of thumb is to set the water level about 3/4" below the top of the overflow pipe.

  • If the float rubs on other parts, simply adjust the float arm sideways. If the float lacks buoyancy, unscrew then shake it to determine if it is waterlogged. A waterlogged float should be replaced. The float arm can also be replaced, if needed.

  • In tanks using modern plastic refill valves, the tank water level is adjusted in other ways. If your tank uses a hand nut, turn the nut clockwise to raise, or counterclockwise to lower, the water level. Or, your tank may have a sliding pinch clamp on an adjustment rod.

  • Flush valve. Replacements for a flush ball and its actuating mechanism are available, but it may be possible to stop a leak with minor adjustments. Check the following mechanisms before purchasing replacements.

  • See that the guide arm is centered directly over the seat. The guide arm should drop the flush ball directly into its seat. If the flush ball is not seating properly, make the adjustment shown.

  • The guide arm should allow the flush ball to rise enough for a complete flush. If not, raise the arm. Be careful that it isn't too high–then it will prevent the ball from closing completely.

  • Check that the upper lift wire pulls the flush ball high enough. To adjust it, simply bend the wire for a higher or lower lift.

  • The lifting hardware on a flapper-type flush valve should raise the rubber flapper to start a flush, but should not hold the flapper up off its seat. If this is occurring, the hardware is adjusted too short. Some types allow you to slide the flapper itself up or down on the refill tube to ensure that the flapper meets the valve seat squarely. The lifting hardware and flapper height adjustments are the first things to check when flapper problems arise.

  • Refill tube. If the bowl-refill tube is out of place, water is routed directly into the tank, rather than replenishing water in the bowl. When this is the case, you will likely hear splashing sounds during tank refill. The refill tube should aim directly into the overflow pipe but should not reach below water level. If the tube extends too low, it will siphon tank water silently away. Fix it by repositioning as shown.

  • Defective refill tubes on some valves can be replaced with new plastic ones. Simply place one end of the plastic tube over the serrated plastic lug on the body of the valve, and place the plastic holder in the top of the overflow pipe.

    Toilet Flapper drops too soon and causes incomplete flush. Replaced with new red Korky, and adjusted chain tighter AND looser.
    Try adjusting the water level in the tank. Most flappers close as the water in the tank flows out to a certain level. Try allowing more water to come in to the tank. I doubt the weight of the chain has any effect on it closing too early.

    Why do i have to hold my toilet lever to flush?
    Hi Nathan:
    If you lift the tank lid off and flush the toilet you will see that a flapper valve lifts to let the water drain from the tank. The flapper valves are designed to stay in the closed position when the tank fills, but to float when the tank is flushed.
    The problem will probably be that the flapper valve no longer floats due to saturation with water, or a leak that has allowed water inside the float.
    The fix is to replace the float valve. Parts are available at most hardware and plumbing supply stores.
    Cheers

    Toilet does not have good flush
    The power of the flush has nothing to do with the fill valve. It has to do with the flapper. When the flapper is opened, the surge of water into the bowl is what causes the toilet to flush. If the flapper closes too quickly, it will take away from the powerful flush. Try to find the correct flapper for that type of toilet and stay away from the "universal" flappers.

    I have the Kohler toilet with the top actuator, it flushes fine but won't stop running. If I lift the tank top I'm making the toilet flush again. Can this be fixed or do i have to replace the whole system?
    (Problem 1) if you can see the water running in the bowl it's a good chance that the flappers warn. you'll have to look at the angle where the light hits the water. The water will be rippling where the top of the water meets the inside of the bowl edge.
    For more info on how a toilet works = http://www.aplumbers.com/residential/toilet
    solution 1
    1. tank the tank lid off.     2. flush, the rubber thing that comes up and allows the water to go to the bowl is the flapper 3. remove 4. replace that should fix it.

     problem 2 it could be the water levels to high.
    (solution 2)
    1. tank tank lid off.     2. if the waters flowing over the long tube in the center and down then the water level is too high 3. adjust the level either it will have a ball **** or a float in either case a ball **** adjusts by a screw on the fill valve. the float has a either a metal rod w/ a pinch clamp or a plastic long screw type thing. 4. adjust water level . 5. lift the flapper to allow a little water out til fill valve kicks on then release handle til valve stops . 6. just keep re adjusting til you get the water level right there should be a molded in line for the level on the back of the tank.

    Flush valve drops before bowl completes flush
    is the flapper weighted? if it is it will cause it to shut prematurely. one thing you can do is increase the water in the tank. you might have to buy a pvc cuppler to put on the over flow to allow it to fill up more. korky makes a nice flapper thats not weighted
