Leaks
The most common point where a toilet leaks is at the junction between
the toilet base and the floor. The base of the toilet has a ringed
opening that fits into the sewer or septic
plumbing called the toilet flange. The flange is a recessed ring that
is attached to the sub-flooring
and floor
framing. To seal the connection, a large ring of pure beeswax,
which acts as a compression gasket, is placed between the toilet and flange
to prevent liquid and gas from leaking. The toilet bowl is then secured to
the floor with two bolts, located on the left and right side of the base.
| Applying excessive or uneven pressure
can cause the beeswax seal to become deformed and the connection to
become loose and leak. Since beeswax gaskets are not elastic,
they do not have a “memory.” (When compressed, the beeswax
keeps the compressed shape and does not return to its original
shape.) So by applying an uneven or excessive pressure to the
bowl, the wax ring becomes deformed and no longer seals the
connection. |
|
| Small failures of the seal will result
in small leaks. Larger problems with the seal will be evident
by the ability to move the toilet bowl side to side in a rocking
motion. To fix the problem, completely replace the wax
ring. Additional repairs may be needed if any damage to the
subflooring, framing or piping is found. Rubber gaskets with a
"memory" are available on the market but are not widely
used. |

Other leaks may develop if the bowl or tank
cracks or if the junction between the tank and bowl (two-piece) fails.
Leaks between the tank and bowl occur when the bolts securing the tank to
the bowl become loose or when the rubber "O" ring gasket that
seals the connection rots or tears. To fix the problem, replace the
rubber "O" ring gasket or tighten the bolt. Cracked toilets need
to be replaced. (Note: Over-tightening of bolts may crack the toilet.)
Flush Valve Mechanism
Another common toilet problem is the tank constantly refilling The
constant refilling occurs when the flap
does not properly seal with the flush seat. This is caused by sediment
or film build-up at the opening or by the flap becoming damaged or deformed.
To fix this problem, clean the opening and/or replace the flap.
If the handle used to flush the toilet no longer works, the chain or string
that connects to the flap may be broken. When the handle is pressed,
the chain lifts the flap, allowing the water to enter the bowl. The
chain or sting may wear out over time. To fix, replace the chain.
