Toto GMax Flushing System drips

2 possibilities.1. The water level is set higher the the overflow tube. This will cause the water to run into the overflow continuously. You should be able to see this. 2. The large seal - bottom center of the tank - is leaking. This will cause the water level to slowly drop after a fill. The water tank will start to run again after flushing - BUT NOT CONTINUOUSLY. You should see if there is a small amount of water flowing from the rim to the bowl 15 seconds after the water has stopped running after a flush.

WHAT IS DRIPPING,?THE TANK ?OR IS STILL FILLING UP ?IT SOUNDS LIKE YOU NEED TO ADJUST THE WATER LEVEL TO THE PROPER 1.6 GALLONS PER FLUSH,WHICH IS MARKED ON THE INSIDE OF YOUR TANK SOMEWHERE,CAUSE WHAT YOUR HEARING IS THE WATER RUNNING DOWN THE OVERFLOW TUBE

Replace as valve is faulty

WATER LEVEL IS NOT PROPERLY ADJUSTED. REDUCE WATER LEVEL TO FILL LINE

You need Korky Part # R528 available at Home Depot. Instructions are on the package and it takes just a few minutes to change it.

The purpose of the "Overflow" tube is to fill the toilet bowl. It should drip for a while. If it is continuously dripping there could be dirt or deposits on the ball **** valve. Shut off the water and dissasemble to see if there is deposits or perhaps a torn diaphragm.

Seams like you have a hair line crack in the intake pipe. I would recomend replaceing it to solve your problem.

This is normal, though not so if it is excessive. Try adjusting the fill valve (there is either a ballcock or a float that surrounds the fill valve). With the ballcock, there is a screw at the top of the fill valve to lower the arm, on the other there is a metal clip to pinch and move the float with a large plastic screw for fine tuning.

I have the same problem and can not find a solution. The toilet flushes fine but then a delay in filling up the tank occurs. Is there a part I can replace? Does something need to be cleaned or cleared?

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!
