4 . Press flush pedal and allow water to completely drain from water valve and vacuum breaker .

Note
Never leave vehicle or premises unoccupied for extended periods of time with municipal
water supply or onboard water pump turned on when there is a possibility of freezing
temperature .
IMPORTANT:
Toilet warranty does not cover freeze-damaged water valve
The Dometic 310 toilet warranty expressly excludes coverage for any damages to the toilet or
vehicle that may occur as a result of improper winterization of the toilet . An indicator of improper
winterization is freeze damage to the water valve which results in leaks.
Dometic 310 toilet water valves exceed maximum
water pressure as defined by North American
plumbing code agencies . However, if trapped water
freezes in piping that supplies water to the toilet, it
expands and creates extremely high pressure that
can damage the valve (see photo) . To avoid this,
winterize the toilet as described in this manual .
If freeze-damage occurs as a result of improper
winterization, replace the water valve with a 310
toilet water valve kit, part number 385311641 .
IF WATER VALVE IS RETURNED FOR WARRANTY
CLAIM, DOMETIC RESERVES THE RIGHT TO
DENY CLAIM IF PROBLEM IS CAUSED BY FREEZE
DAMAGE.
