If you find your toilet running
constantly the problem is most likely related to one of three things. The
toilet flapper is no longer forming a good seal at the bottom of the toilet
tank, the float is not working properly causing the water to continuously
run and empty into the overflow tube, or the toilet tank fill valve is
failed. If the toilet tank fill valve has failed you can easily find a
replacement one and replace it yourself. Alternatively you can call in a
plumber to install a new toilet tank fill valve, however expect to spend
$100 or more. |

To install a new toilet tank
fill valve first turn off the supply line valve to the toilet and flush
it a couple of times to drain out the residual water in the tank. The
supply line valve is typically located underneath the toilet on either
the floor or back wall.
Next remove the toilet tank
lid, and use a bucket and either a large rag or sponge to sop up any
remaining water in the toilet tank.

After sopping up any remaining
water in the toilet tank disconnect the water supply line tube end that
connects to the base of the toilet tank. You should be able to disconnect it
with your fingers, however you may need an adjustable pair of pliers to
initially loosen it. Note, keep you bucket or rag handy to catch any
residual water in the toilet tank.
Next disconnect the overflow tube
from the toilet tank fill valve. Then, while holding the toilet tank fill
valve firmly in one hand, loosen the large plastic nut that holds it in
place with the other hand.

The large plastic nut can be
found on the underside of the toilet tank, where you disconnected the supply
line hose. Again, you should be able to loosen it with just your hands.
Once you have removed this nut
you should be able to pull the old toilet tank fill valve out of the toilet
tank.
Now install your new toilet tank
fill valve into the toilet tank, basically working in reverse. Secure the
new toilet tank fill valve with the gaskets and nut that came with it to the
bottom of the toilet tank. One gasket should sit directly underneath the
toilet tank fill valve and the other directly underneath the nut. Initially
finger-tighten the nut onto the base of the new toilet tank fill valve and
then gently snug it down with an adjustable pair of pliers. Make sure,
however that you do not over-tighten it.

Then connect the overflow tube
the top of the toilet tank fill valve.
Next, connect the supply line
hose back to the base of the toilet tank, again initially finger-tightening
it and then snugging it up with the adjustable pliers.
Finally, turn the supply line
valve back on and let the toilet tank fill. Check for any leaks around the
toilet tank fill valve area. If all was done properly your toilet should be
leak free and functioning properly again.
