Leaking toilets cause more water waste than any other fixture in
the home.
Even a silent toilet leak (that's one you normally can't hear) will
waste from 30 to 500 gallons of water per day! The ones you can
hear will waste much, much more. Such wastage can normally be attributed
to a faulty water level adjustment or to a leaky flapper.
Leaky
flappers and the "dye test.
Most people will say their toilet does not leak. There is one sure
way to find out. Put some food dye in the tank and then leave for
15 minutes. When you return, look into your bowl to see if there
is now dye color in the water spot. If there is color, or if you
already can hear and or see water running in your bowl, it's time
for a new flapper!
Deformed
flapper valves are often the result of toilet tank cleaning products.
If you choose to change the flapper yourself, the best bet is to
remove your old flapper and take it with you to purchase a new one.
Removing the old flapper is easy but can be messy if it is partially
disintegrated. A pair of cheap latex gloves and a small container
to hold the old flapper will make your job less of a hardship.
When
removing your old flapper, you will first need to turn the water
off at the shut-off/supply valve. Next, disconnect the chain or
tail from the trip lever arm and then slip the ears of the flapper
off of the trunion ears. You will need to select a new flapper that,
as near as possible, matches your old one. If your flapper is one
of the hard-to-find ones, you may even need to contact the manufacturer
of your toilet for a recommendation, so if you only have one toilet,
it's a good idea to keep the old flapper handy until you've found
a suitable replacement.
While
the flapper is out, take your finger and move it over the seating
surface of the flush valve seat -- that's the part that the flapper
sets on to seal the water. If the surface is rough, this needs to
be fixed, too. If the flush valve is plastic, it will need to be
replaced. This can be a bigger job and will probably require a plumber
(see the next paragraph and evaluate whether you want to tackle
it yourself). If the flush valve is brass, you may be able to fix
it yourself. Get some 400 grit wet or dry sandpaper and lightly
go over the entire surface. Repeat the process until the surface
is smooth. For toilets with a flat seal type of flapper, simply
slip it off the piston or other holding device and replace it with
a new one.
After
installing the new flapper, run the dye test again to assure you
have no leak. If the leak persists (and every now and then it will),
you are probably going to have to replace the entire flush valve.
To do this, you will need to turn your water off and disconnect
the supply line. Then loosen the bolts that hold the tank to the
bowl, remove the tank to bowl seal and remove the flange nut on
the bottom side of the tank which holds the flush valve in place.
Next purchase a replacement valve assembly, but be sure that the
new assembly has an overflow tube at least as tall as the old one.
If the new one is taller, then note the correct height from the
old one, mark that height on the new one and, using a hack saw,
cut it to the proper length. Using new seals, reassemble in the
reverse order as used in removing the old valve.
"It
only runs in the middle of the night"
Many toilets really do run only at night; that's because people
use much less water during these hours and in many municipal water
systems, the water pressure rises considerably during this time.
It is not uncommon for system water pressure to rise by 15 to 20
pounds per square inch (psi), and by as much as 30 psi in some situations.
This rise in pressure could cause "water creep" inside
your gravity fed tank by 1/2 inch or more. That is why the
manufacturers of toilets normally suggest that the water level to
be set at approximately one inch below the top of the overflow tube.
Water
Level in the tank
If you only notice your toilet running in the middle of the night,
there is a good chance that the water level in your tank is set
too high. Remove your tank lid and observe the water level. If you
are doing this in the middle of the night (which, by the way, would
be the ideal time to check this out!), and the water is running
over the top of the overflow tube, adjust it down using the adjusting
screw on the top of the fill valve mechanism (turn clockwise) or
the "V" shaped clip on the stiff wire link (slide it down)
on the "sliding float" so it's not overflowing. Then,
the following day, make another adjustment down to the one-inch
level.
