The water level in the bowl can be

different pressure is used.
Tank Level Sensors
The Tecma toilet system includes a black
tank level sensor. The water icon located in the
bottom right corner of the control panel denotes
tank level and system status.
Full Tank Lockout:
The toilet will not ush when the system
senses a full tank. This will prevent system
backup and occurs when the Water Icon is red.

DRAIN TRAPS & AUTO VENTS
Sinks, shower and clothes washer drains
incorporate a water trap (P-Trap) and auto vents
to prevent waste water holding tank odor from
entering the motorhome.
Drain Traps:
P-Traps are usually within 54" of a vent tee
and must contain water to block odors. During
storage water can evaporate and allow odor
into the motorhome. If odor is detected, run
water into sinks, shower and clothes washer to
ll P-Traps.
Auto Vents:
The auto vent is designed to assist in the
smooth ow of water in the drain without
creating a vacuum. If stuck in the open position,
the auto vent can allow grey odors to enter the
motorhome. Some auto vents can double as
“clean outs” in the event the line needs to be
snaked out.
