Closet tanks and bowls are made of vitreous china
and are impervious to ordinary household acids. If something more than
hot water and soap is needed to clean them, apply a non- abrasive powder
or cleaner recommended by your plumber. Many good bowl cleaners are on
the market today. Most plumbers however, have found that the "blue water"
continuous bowl cleaners tend to accelerate the deterioration of the rubber
and neoprene parts in the tank, due to the chemicals they contain.
Seat bumpers should be replaced if worn. Defective
bumpers may cause breakage of the seat or hinges.
Stains or moisture at the base of the closet bowl
indicate that the joint or seal between the closet and its outlet have
failed and should be reset immediately to prevent rotting of the floor,
damage to the plaster of the ceiling below, and possible leakage of sewer
gas into the home.
Water Closet Tanks
If water continues to run into the closet bowl after
the toilet is flushed, it is obvious that some part of the mechanism is
out of order.
When the tank has refilled, if water continues to
seep into the bowl or if there is a low humming noise, this indicates
leakage from the tank. This leakage can occur from either the supply valve
or the improper seating of the rubber tank ball or (flapper) on the discharge
A small amount of food coloring added to the tank
water will help you determine whether the tank ball in the bottom of the
tank is leaking. Add it to the water aver the tank is filled. Watch for
the coloring to seep into the toilet bowl, and if it does, the ball or
flapper over the discharge opening is not water tight If the rubber tank
ball does not fit tightly over the discharge opening, a defective ball,
irregular seat or bent lift wires may be responsible. If the ball is worn
out, misshapen or has lost its elasticity and fails to drop tightly into
the hollowed seat, it should be replaced with a new one. Sometimes the
ball is covered with a slimy coating which can easily be wiped off. To
replace the ball, shut off the water supply (a stop is installed underneath
the tank where the water may be conveniently shut off at this point) and
empty the tank or place a stick under the ball float lever-arm to hold
it up, thereby shutting off the intake cock and preventing the tank from
refilling. Then unscrew the ball from the lower lift wire and attach a
new ball of the same diameter as the old one. (Note: some old
tank balls swell from age and absorption of water.)
If the collar or seat of the discharge opening is
corroded or grit-covered, it should be scraped and sand-papered until
it is smooth and forms a uniform bearing for the stopper.
Straighten or replace bent lift wires so that the
ball drops squarely into the hollowed seat.
A leaky, waterlogged float ball holds the supply valve
open and does not completely shut off the water. If the rod which connects
the tank float to the supply valve has become bent, it may prevent the
float from reaching its full height, thus leaving the valve open and allowing
leakage. This rod should be straightened and a little oil applied to the
lever joints to insure smooth action.
Sometimes the tank will not fill sufficiently or will
fill to overflowing. These difficulties may be corrected without disturbing
the supply valve by bending the rod attached to the tank float upward
or downward. If the rod is bent upward, the water will rise higher in
the tank, and if downward, the water level will be lowered.
An overflow tube or pipe is provided in the closet
tank to take care of the water in case it should rise above its accustomed
level which should be at least 3/4 of an inch below the top of the overflow.
While there is not much danger of its becoming stopped up, it might be
well to examine it occasionally to see that it is in working order.
If water rises to the top of the overflow pipe an
adjustment or new fill-valve assembly is necessary. Consult your plumber
if in doubt.
