Flush ball seal – Dometic’s
revolutionary ball seal allows future

ball seals without requiring tools or
toilet disassembly. The ball seal can
be changed in just a few minutes
without removing the toilet from the
oor. Detailed replacement instruc-
tions are included with replacement
ball seal kits.

Factory-sealed bowl-to-base as-
sembly – Unlike other Dometic foot-
pedal toilets, the bowl and base of
310 and 320 series toilets should
not be separated for any reason.
Each Dometic toilet is 100% factory-tested to assure a watertight seal in the toilet bowl before
it is shipped.
After installation at the RV or other vehicle factory, the entire toilet and waste tank system is ood-
tested for leaks by lling the system with water to the rim of the toilet bowl. This process requires
holding the ush ball open with a device which may temporarily distort the ball seal from its original
shape and, as a result, cause the seal to leak water into the waste tank during normal use. The ball
seal may need to be reconditioned to its original shape.
IF NEW TOILET DOES NOT HOLD WATER IN BOWL…
Please follow the procedures below before attempting to replace the seal.
1. Hold ush ball in full open position by pressing on
pedal.
2. Using nger, apply moderate downward pressure
around edge of ball seal.
3. Close ush ball.
4. Keeping ush ball closed, pour one quart of
hot tap water into toilet bowl.
5. Let water cool completely.
6. Check for leak.
If leak still persists, ush ball seal should be
replaced. Follow instructions provided with
replacement seal kit.
