Draining The Fresh Water System
A recreational vehicle with a demand pressure pump system will
have low-point drains attached to the water lines. These low-
point drains will release water in the supply lines by opening
the valves and all faucets. To drain the permanent fresh water
supply lines:
1. Turn the water heater power OFF.
2. Drain the Truma Combi tank. It is equipped with its own
pressure relief valve.
3. The valve next to the pressure relief valve will drain the tank.
4. Open all faucets.
5. Open the “fresh tank drain” valve located on the underside of the vehicle close to the
water tank.
6. Open the low point drain valves. There is a label on the outside of the RV to indicate
where the drains are located.
7. Drain the sink by removing the drain cap.
8. Turn ON the water pump and allow it to run as needed.
9.
If the water heater has bypass valves, set them to the BYPASS configuration (refer to
the
Water Heater Bypass
section).
10.
Operate the toilet flush lever until water stops flowing.
Some water may remain in the lines. If the recreation vehicle will be exposed to cold tem-
peratures, it must be winterized to protect the plumbing system and components. Damage
to the water lines and components due to freezing is not covered by warranty. Refer to the
Sanitizing/Winterizing the Plumbing System
for details.
NOTE:
See the Truma Combi Operating Manual for important safety and
operating detail.
Risk of scalding injury from hot water and/or tampering with the pres-
sure relief/drain valve.
Never actuate the pressure relief/drain valve as long as the Combi furnace is
still hot.
Do not place a plug or reducing coupling on the outlet part of the valve. If you
use a discharge line, allow the valve and the line to drain completely.
NOTE:
To empty the fresh water tank, locate the drain valve under the
vehicle chassis close to the tank location. This will empty the tank only.
