SeaLand 320 Series RV Toilet - Manual (Page 10)

IMPORTANT:
Toilet warranty does not cover freeze-damaged water valve
The Dometic 300, 310 and 320 series 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 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, winter-
ize the toilet as described in this manual. If freeze-
damage occurs as a result of improper winterization,
replace the water valve with a 300/310/320 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.
