Cleaning

Drain Traps & Auto Vents
6 • 2 4 8
The toilet should be cleaned regularly for maximum sanitation and operational
efficiency. Clean the toilet bowl with a mild bathroom cleaner. Do not use
chlorine or caustic chemicals, such as drain opening types, as they will damage
the seals.
Clean out the system by using the tank flush system. If additional flushing
is desired, flush with several gallons of fresh water and one cup of dry laundry
detergent. Add odor control deodorant, in the amount specified for your holding
tank capacity, after cleaning and every few days during use.
Checking for Leaks:
• Back of toilet: check water supply line connection. Toilet tissue works
well to find leaks. The tissue changes texture when it contacts moisture.
• Between closet flange and toilet: Check flange screws making sure
they are snug. Do not over tighten screws. If leak continues, remove
toilet and check flange height. Adjust, if necessary to 7/16" above
floor. Replace flange seal if damaged.
• Poor flush: A good flush should be obtained within 2 to 3 seconds. If
problem persists, adjust the water level. If it continues, the water pressure
may be low or the water flow rate is low. Remove the water supply
line and check flow rate. The flow rate should be at least ten quarts
(9.5 liters) per minute. Water pressure should not be below 25 psi.
• Bowl will not hold water: Check for foreign material in ball valve.
NOTE: If the motorhome is in storage for six months, it is a good idea
to spray silicone on the ball valve. Perform this maintenance monthly
(silicone will evaporate in about 30 days).
070152 Water Trap
Sinks, shower and clothes washer drains incorporate a
water trap or "P-trap" and auto vents to prevent waste
water holding tank odor from entering the motorhome.
These P-traps are usually within 54" of a vent tee. These
traps must have water in them to block odors. During
storage water can evaporate and allow odor into
motorhome. If odor is detected run water into sinks,
shower and clothes washer to fill drain traps. The auto
vent by design is to assist in the flow of water in the
drain lines. They enable a smooth flow of water in the
drain without creating a vacuum.
The auto vent, if stuck in the open position, can allow
grey odors to enter the motorhome. These auto vents also
double as "clean outs" in the event the line needs to be
snaked out.
