JAYCO TOWABLE SECTION 8 – PLUMBING SYSTEM

need to be opened from inside the RV. Once the label is found on the exterior
sidewall, go inside the RV to find the corresponding location of the drains.
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). Disregard if there are no bypass valves.
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
When to sanitize:
When your recreation vehicle 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
1. Turn water heater power OFF (storage style-both electric and LP gas switches;
tankless water heater turn power switch OFF).
2. Set the bypass valves to bypass the water heater; valves A&B closed and valve C
open (refer to Water Heater Bypass Valves section).
3. Level the RV and drain the fresh water system (see Draining the Fresh Water
System).
4. Close the low point drain valves and the fresh water tank drain valve.
5. Remove the water filter from the full system canister in the basement area of the
motor home (see Water Purification section). Re-attach the empty canister and turn
the water supply valves at the filter ON.
6. 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; contact your dealer or customer
service for your specific tank size.
7. Put the sanitizer solution in the fresh water tank: Insert one end of a hose (or funnel)
in the gravity fill inlet, insert the other end into a container holding the chlorine
solution. Do not use your non-toxic drinking water hose. Pour the chlorine
solution into the gravity fill.
8. Remove the hose (or funnel) and container used to pour the chlorine solution, and
continue filling the fresh water tank with clean (potable) water until tank is full: Pour
fresh water into the gravity fill inlet until tank is completely full.
