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.
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 pressur-
ized source, or from a container (as detailed below).
a. Filling from a pressurized source: Set the valves to the
setting. Connect a non-toxic drink-
ing 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,
disconnect the hose from the water source rst, then disconnect from the utility pan-
el.
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 out-
side shower) until chlorine smell is gone. Set the valves to
the DRY CAMPING setting. Turn the pump ON to send
water through the lines.
5. Close all faucets including outside shower. Turn pump
OFF.
6. Drain the system again, but do not drain the water heater (water heater power still OFF).
7. Close low point drains and fresh water tank drain.
8. Rell the fresh water tank with clean potable water. Use the city water ll connection
inlet and one of the two methods explained in Step 3.
