5 .7 Reconditioning the Flush Ball
Seal
Each toilet is factory-tested to assure a watertight
seal in the toilet bowl. This quality-assurance
testing process requires a device to hold the
flush ball open, which may temporarily distort
the flush ball seal from its original shape. As a
result, it may cause the flush ball seal to leak
water into the holding tank during normal use.
If you discover a water leak into the holding tank,
recondition the flush ball seal into its original
shape.

1. Depress the pedal to hold the flush ball
open, then lightly press down around the
edge of the seal with a finger to conform the
seal to the flush ball.
2. Release the pedal.
3. Keeping the flush ball closed, pour 1 qt
(0.9 L) of hot tap water into the toilet bowl.
4. Let the water cool completely.
If the toilet does not hold water in the bowl, refer
to "Troubleshooting" on page 15 before you
replace the flush ball seal.
