5. Drain the sink by removing the drain cap.
6. Turn ON the water pump and allow it to run as needed.
7. If the RV water heater has bypass valves: A&B are closed, valve C is open (refer to
the Water Heater Bypass section).
8. Operate the toilet flush lever until water stops flowing.
9. Relieve the water pressure using the P&T valve BEFORE removing the water heater
drain plug. If there is any water pressure present the water will spray out of the
opening when the drain plug is removed.
When you are finished draining the fresh water system, reverse these steps and dump the
grey and black water holding tanks at an appropriate facility or according to local public
codes.
It is normal for some liquid to remain in the fresh water tank after drainage procedure.
Sanitizing the Plumbing System (With Uni-Dock Utility
Center)
When to sanitize:
When your RV is new.
At the beginning and end of each season.
When the water system becomes contaminated or every three months of use.
Sanitizing Instructions:
1. Turn water heater power OFF. (both switches: Electric & LP gas) Set the valves to
SANITIZE as indicated on the Utility Center label. (Setting these valves bypasses
the water heater automatically.)
2. Level the recreation vehicle and drain the fresh water system. (see Draining the Fresh
Water System).
3. Close the low point drain valves and the fresh water tank drain valve.
Full System Canister water filter (if so equipped): Remove the canister; take the
filter out of the canister, then reattach the empty canister.
Bypass the cartridge water filter (if equipped). Use the clear plastic tube (supplied
with RV) to bypass the water filter.
4. Prepare a chlorine solution using 1/4 cup of household bleach (sodium hypochlorite
solution) to one gallon (3.785 liters) of water in a container. Prepare one gallon of
solution for every 15 gallons of tank capacity. This will result in a residual chlorine
concentration of 50 ppm in the water system.
If a 100-ppm concentration is required as discussed in step 12, use ½ cup of
household bleach with one gallon of water to prepare the chlorine solution. One
gallon of the solution should be used for each 15 gallons of tank capacity.
NOTE: Fresh water tank sizes vary by model, please contact your dealer or
Customer Service for your specific tank size.
5. Put the sanitizer solution in the fresh water tank:
Attach a hose to the City Water Connection inlet. Insert the other end of the hose into
a container holding the chlorine solution. Do not use your non-toxic drinking
water hose.
