The toilet is not filling properly. The small hose is not plugged. There is sufficient pressure coming into the tank. It appears to be a problem in the housing on the left side????

Check the fill valve for any obstructions, or the diaphragm under the top cover. where the small hole attaches to the top of the fill valve. Why was it removed? If due to blockage the blockage may still be inside the bowl trap.

#K4421 Re black specks coming from rim jets (only). Me too. Looks like bits of rotting rubber. Water in tank is clear-no specks there. I suspect the small hose from fill valve to top of flush piston may be breaking down, as it has gone rigid and I'm afraid to squeeze it lest it shatter. First thing I'll try is replacing that hose, if I can find one.
My daughter has same toilet but no "specks". With her toilet, it's the same small hose but the problem is it occasionally pops off at fill valve end. I can fix that with wire but when I find hose source, I'll buy two.

1. Is the toilet plugged or partially plugged. I have removqed toothbrushes, combs, toys etc. from toilet traps so check for any obstructions.
2. Rust and scale buildup. The buildup of rust , sediment and or scale in the internal passages of a toilet can greatly affect their performance.clean the small holes under the rim with a small piece of wire. Use Limeaway or CLR to remove rust and scale. put some in the tank and flush toilet. Let sit for a while and repeat.
3. Improper venting or plugged vent. A toilet needs a properly vented drain to work correctly. Check the vent to make sure it is not plugged or in the northern climates frosted shut.
4. Mechanical issues. Is the flapper lifting high enough when flush lever is flipped. Is water at correct height in tank. If it is a pressure assist is water pressure high enough. Is pressure tank waterlogged.
These are just afew of the many things that can cause a poor flushing toilet. Hope this helps.

The small tube that comes from the Korky fill valve needs to go down the center of the tube in the tank. It should have come with a clip to clip it inside the fill tube. If the tube is running water into the tank it is just filling up the tank, not the bowl. The tank is filled with the Korky valve from the top of the tower, not the black hose. See the video below to see the black tube I'm referring to and where it should be attached.

Adjust the float attached to the fill valve. Some simply slide up and down on a racheted adjustment bar. Others screw up and down for adjustment. Flush after each adjustment until the proper fill level is acheived. Make sure there is still a sufficient amount of water at a given level to flush the toilet properly.

The controler may be worn or the o-ring gave out. Hope this helps.

If I understand you correctly you remove the tank and looked into the opening of the bowl where the tank attaches. There is usually a dollop of white silicone sealer. This is to plug a pssage created when the toilet was manufactured. Removing this will cause the toilet to not operate properly. If the hole is not sealed properly seal with a good grade silicone sealer. Make sure surface is dry before applying. Hope this helps.

Okay Howard. It seems that the fill or float valve inside the toilet tank needs to be replaced. If you have a pair of channel locks / large pliers and some patience, you can do this yourself and save $ on a service call. This Solution is providing that you have good water pressure everywhere else in the house. First turn off the water on the supply line going to the tank. Flush the toilet (with the water off) to empty the tank. Take a towel / sponge / or wet vac to remove any remaining water. Remove the nut on the underside of the tank that holds the float / water supply to the tank. Now that you have the water float removed you can go to your local hardware store / Home Depot / or Plumbing Supplies Store and get a new fill valve. There are different kinds but they all do the same thing, fill your tank. I use a Fluid Master, But you may have to use one like you have. The Store will assist you. They are only about $10 - $15 Bucks or so.......Install the new float according to directions.....It is pretty simple. Insert your new float stem into the hole with the proper rubber washers and tighten carefully for a good seal. Insert the new black hose into the overflow tube and you are in business. You will have to adjust the water level to about a 1/4 Inch below the overflow tube for a good flush!!! I hope this helps you with the slow tank fill.............Joe

Remove the tank lid and look at the fill valve. Is it a yellow valve?
This fill valve is common on the Toto Toilets and can easliy plug with debrie.

They can be disassmbled and cleaned. however, I usually just replace the valve with Fluid Master Fill valve.
You will also want to check the water coming into the toilet by turning off the water that supplies the toilet and disconnecting the water supply line. After removing the water supply line turn on the water at the valve to make sure that the water is flowing properly. Check the supply line also to make sure it is not plugged.
Be sure and place a small container to catch the water that will come from the valve. A towell will also help from making too much of a mess.
If the Supply line and the valve are clear the problem is in the fill valve.
The G-Max system denotes the Flushiing system which is a 3" flapper that allows the water from the tank to flow into the bowl quicker.
Good Toilets!
