Even when I turn my water suppy off going to my

Valve fully open on inlet going into toilet if it is then fill valve needs to be replaced check water line for any abstructions that might interfere with water going into tank.

When you turn on the supply the tank fills ok. I don't know the mechanism in your tank but fixed a similar problem. Check the flap that releases water to flush, if it CLOSES properly after flush otherwise it lets the water into the toilet continuously making the sound. IF closed properly, the tank fills.

The fill valve sounds if it is bad.Go to lowe's and get a fluidmaster fill valve(about $8) instructions included.turn off water and remove water from tank then disconnect supply tube,remove old fill valve install new,follow installation diagram,and the adjustment process to adjust the water level to correct level that should take care of your problem.

If there is a continual leak in to the toilet bowl you will likely need to replace the flush valve or the toilet flapper.

As a first step try try cleaning the sealing surface of the flush valve to se if the flapper will seat and make a seal.

If this does not work and the flapper is visibly detioriated and breaking down shut off the water supply, remove the toilet flapper and visit your local plumbing supply store to purchase a suitable replacement. Install the new flapper, turn on water supply.

Although less likely, if the sealing surface of the flush valve is damaged or detioriated proceed with replacement of the flush valve. Again turn off water supply and follow the instructions set out here:

If there is not a leak in to the toilet bowl and the water flow does not shut off completely, then water is flowing through the fill valve and the overflow pipe and you may need to adjust the float and float rod to allow clsoure of the fill valve. See here:

Is the flapper valve slow to return to the closed postion allowing water to flow through the flush valve? Make sure the toilet flapper is moving freely and is sealing properly against the flush valve. If there is no lengthy or continual water flow in to the toilet bowl then this is not the problem.

Is the water valve on the water fill line to the toilet tank fully open? This may seem silly but it could be this simple.

Check to make sure your fill valve is opening fully. If you have an older toilet there may be some deposits that need to be cleaned way to allow free movement.

If toilet does eventually fill to the desired level, there is no leakage, water valve on fill line is fully open and fill valve is opening fully then recommend you shut off water supply, drain toilet and disconnect water fill line from the water valuve and toilet tanke to make sure there is not a blockage. If the water line and connections are clear you may need to remove the fill pipe in the tank and check for blockage. If this is very old, conisdering the cost and effort, it may be simpler to replace at this time rather than trying to extend the life.

replace your flapper!!!!!!!!!!

it sounds like one or more of your shut off valves has a glog from hard water calcium. were from indiana its a big problem here.To check this u will have to shut off main water supply and remove top of shut off valve and check for white crusty blockage, even if u see a few particals its present. It can severely restrict flow.

shut the water off to the toilet .Remove the toilet supply from the tank end.slowly turn the valve on to see if their is any water coming thru the supply.If water is coming thru the supply than you know you need to change the ballcock.This is the part in the tank where the water comes out of.

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!

Chances are the flapper is leaking. Thats causing the random refilling as the tank slowly loses water into the bowl.
Replace the flapper with only the best available at your supply house. the cheap ones tend to leak even when new. The good ones are less than 8 bucks most places.

If your fill valve has the float ball, there should be a screw right on top of the fill valve at the end of the rod holding the ball to adjust the water level.
Closckwise lowers the level.

Be carefull not to break the plastic ones. If the adjustment is all the way in or does not work, you will need to replace the fill valve.

You could also try bending the metal rod holding the ball, but only as a last resort.
