TOILET DOES NOT NEED TO BE REMOVED FROM VEHICLE FOR BASIC REPAIRS (if necessary)
Flush ball seal – Dometic's
revolutionary ball seal allows future
replacement of worn or damaged
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
floor . Detailed replacement instruc-
tions are included with replacement
ball seal kits .
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 flood-
tested for leaks by filling the system with water to the rim of the toilet bowl . This process requires
holding the flush 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 MODEL 310 TOILET DOES NOT HOLD WATER IN BOWL...
Please follow the procedures below before attempting to replace the seal .
1 . Hold flush ball in full open position by pressing on
pedal .
2 . Using finger, apply moderate downward pressure
around edge of ball seal .
3 . Close flush ball .
4 . Keeping flush 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, flush ball seal should be
replaced . Follow instructions provided with
replacement seal kit .
