16. Drain the fresh water system again. If the RV has the full system canister water lter,
remove the canister, reinstall the lter, and reattach the canister.
17. Rell the fresh water tank with fresh water again and when water heater is full of water,
turn the water heater power ON.
If a chlorine taste lingers in the water, ush the water system
with a solution consisting of one-quart vinegar to ve gallons of clean water. Re-ush as
necessary. The vinegar solution may damage the water heater or the water lter, so both must
be bypassed again before performing this operation.
Follow the steps outlined in Draining the Fresh Water System with one exception, do not
drain the water heater. Do not remove the water heater drain plug.
For the water lter: remove the canister, take out the lter, then re-
attach the empty canister.
After draining the system:
1. Water heater power should still be OFF. (both electric & LP Gas
on standard storage water heater). Single switch inside the RV
for the Truma AquaGo tankless water heater.
2. Put the vinegar solution into the fresh water tank; set the valves
to the setting.
Attach a hose to the city water ll inlet. Put the other end of the hose in a container with
the vinegar solution. Turn the pump ON.
The solution will be drawn into the fresh water tank (the water heater will be bypassed
automatically). When the container is empty, turn pump OFF, and disconnect hose
from utility panel.
To aid in siphoning, place the container approximately (2) feet o the ground. The
drain valves must be closed.
3. Fill the fresh water tank full of clean (potable) water. Use water from either a pressurized
source, or from a container (as detailed below).
a. Filling from a pressurized source: Set the valves to the
setting. Connect a non-toxic
drinking hose to the city water ll inlet. Connect the
other end of the hose to the pressurized water source.
Turn on the water source. When tank is full, turn o the water source,
then disconnect from the utility panel.
b. Syphon lling from a water container: Set the valves
to the setting. Insert a hose into the city
water ll inlet, place other end of the hose in a container
of water. Turn pump ON to draw water into the tank.
After the tank is full, turn the pump OFF. Remove the
hose and the container. To aid in siphoning place the
container approximately (2) feet o the ground. The drain valves must be closed.
4. Run water through all faucets (hot & cold, including outside shower) until chlorine
smell is gone. Set the valves to the setting. Turn the pump ON to
send water through the lines.
