PLUMBING
Care and Maintenance
Waste Water Drain Lines
The drain lines are plumbed from the sinks, showers, and
toilets are sloped to drain waste water to the grey or black
tank. However, if the coach is equipped with a lift pump,
refer to the “Lift Pump” article. If the coach is equipped
with macerator toilet(s), refer to the toilet article(s).
The drain lines connecting slideout-installed components,
such as the kitchen sink and other optional equipment
utilizing the coach water supply, are typically hard-
plumbed within the slideout. The hard plumbing from the
kitchen slideout connects to the hard plumbing from the
tank using a braided drain line to ensure flexibility as the
slideout extends and retracts. The fresh water plumbing
lines are normally tied to the flexible drain pipe and extend
and retract smoothly as the slideout travels.
Avoid using “S.O.S.” type cleaning pads or other
abrasive cleaners because they may scratch the
surface. Do not use cleaners that contain harsh or
abrasive chemicals. Alcohol or similar solvents should
never be used.
IMPORTANT
!
The maintenance requirements for sinks and the shower
are on an as-needed basis. Occasionally, the attached
drain and trap may need to be cleaned of soap scum and
hair to maintain efficient drainage. The basins and shower
walls can be cleaned to maintain the original luster. Clean
the entire surface, including the exterior, of the lavatory
and kitchen sinks and shower with mild soap and warm
water. Wipe the entire surface completely dry with a
clean, soft cloth.
Follow these tips to maintain the shower(s) in the coach:
1. Make sure the shower doors are closed and latched
or locked prior to travel.
2. Check for leaks in the shower seals. Reseal them as
needed.
3. Using a mild detergent and a soft cloth, wipe down
the shower walls and glass enclosures after each use
to avoid soap scum and hard water deposits.
4. When winterizing the coach, clean up any remaining
antifreeze in the shower, as it may cause staining.
P-Traps and Waterless Traps
This article provides an overview and care and maintenance recommendations for traditional and waterless p-traps.
P-Traps
The sinks and shower drain have a water trap to prevent
holding tank odors from entering the coach. These traps
must have water in them in order to trap the odors. While
traveling, the water may leave the P-Trap. While stored,
the water may evaporate, allowing an odor to enter the
coach. If this occurs, run water from the faucet into the
drain, allowing water to fill the trap.
Waterless Traps
Some coach models with a rear shower may have
waterless traps in lieu of conventional P-traps. Waterless
traps are designed to allow water to drain and to
prevent odor from entering the coach without the height
requirements of the conventional p-trap. Pressure builds
and the self-sealing valve opens as water drains from
a fixture. The valve closes to form a tight seal after the
water has completely drained from the sink or shower.
No routine or seasonal maintenance is required for the
waterless trap.
