WATER SYSTEMS
Doc No: 21906503 Rev: 05 Copyright © Roadtrek Motorhomes Inc. 2007 G - 5
Waste Water Tank Flushing:
To flush the waste water tanks:
1. Ensure that both tanks are empty.
2. Fill the black waste water tank by inserting a hose into the toilet, (be sure to step on the flush pedal, so the
flapper door stays open to prevent toilet overflow) and fill the grey waste water tank using the sink.
3. Dump both tanks using the procedure outlined on Page G-4.
OUTSIDE SHOWER:
NOTE: Outside shower can only be used in summer
operation mode. Shut off valves are located in the vehicle’s
interior.
The outside shower faucet is found in the small compartment
to the rear of the large driver side storage compartment, (the
shower hose is stored in the large compartment when not in
use). Remove the shower hose from the storage
compartment and attach to the shower faucet spout, (see
Picture G-P11).
NOTE
:
The shower hose must be returned to the large
storage compartment before travel, as to prevent
damage to the unit.
POTABLE WATER SYSTEM DRAINING:
NOTE: Water system must be in summer operation mode.
To completely drain the fresh water system of all water:
1. Ensure that the water pump is off and that your vehicle is level.
2. Ensure that the tank isolator valve is in the open position, (190 models).
3. Drain the fresh water tanks and the hot and cold fresh water system by opening the exterior fresh water
drain valve at the low point drain on the exterior fresh water tank, (see Pictures on page G-9).
4. Open all water outlets including the sink faucet, aisle shower faucet, external shower faucet, and toilet
flushing pedal. The toilet flushing pedal can be propped open or opened manually several times. This
procedure allows gravity to draw any remaining water out through the exterior fresh water tank drain.
5. Your vehicle is equipped with a water heater, follow the manufacturer’s instructions for draining.
6. Open the sink faucet and turn on the water pump until water is no longer pumped.
7. Turn off the water pump.
If this procedure is followed, it is NOT necessary to blow out the water system. Once the system is drained, be sure
to close all faucets before driving.
NOTE: Do not allow water to sit in sewage and fresh water tanks when vehicle is not in use.
