8. Relieve the water pressure using the water heater P&T valve (if so equipped)
( Fig 8.5 located outside RV). Water heater will drain out of the low point
drains.
When you are finished draining the fresh water system, reverse these steps and,
dump the black water holding tank (if so equipped) 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
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.
How to sanitize with a GRAVITY FILL and the water pump:
1. Turn water heater gas valve OFF (if so equipped). (located outside RV)
2. Level the RV and drain the fresh water system. (see Draining the Fresh
Water System ).
3. Close the low point drain valves and the exterior fresh water tank drain valve.
( Fig 8.7 & 8.8 )
4. Bypass the cartridge water filter (if so equipped). Use the clear plastic tube
(supplied with RV) to bypass the water filter.
5. 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 RV model, please contact your
dealer or Jayco Customer Service for your specific tank size.
6. Pour this chlorine solution in at the Gravity Fill connection. Do not use your
non-toxic drinking water hose for this. Remove the hose & container.
7. Fill the fresh water tank using a different container with clean (potable) water
until the fresh water tank is full. (Refer to Using the Gravity Fill section)
8. After the recommended amount of sanitizing solution is in the tank, the water
tank is full, and water filter bypassed (if so equipped), turn the water pump
switch ON.
9. Open all hot water faucets one by one until water begins to flow continuously
and a chlorine smell is noticeable. (include outside shower faucets if so
equipped)
10. Close the hot water faucets and repeat opening all cold water faucets one by
one until you smell chlorine. Include outside shower faucets (if so equipped).
11. Turn OFF the water pump switch.
12. Let the solution remain in the system for at least four hours when disinfecting
with 50-PPM residual chlorine. If a shorter time period is desired, then a
100-PPM chlorine concentration should be permitted to sit in the system for at
least one hour.
