Normal Setting; Sanitize / Winterize Lines; Fresh Water Holding Tank; Water Heater Bypass - Jayco Swift Owner's Manual

Section 8: Plumbing System
Normal Setting: Allows you to use the water system when dry camping. The water pump
circulates water from the fresh water tank to all the fixtures. If needed, sanitize the water
system prior to travel.
1. Set the bypass valves to the NORMAL position (supply line valves ON.
2. Place the utility center valves in the "NORMAL" position.
3. Turn the water pump ON (make sure you have sufficient 12-volt power).
4. Water will be pumped from the fresh water tank to all faucets.
5. Enter the motor home and open the cold water supply faucets to bleed air from the wa-
ter lines. When the water lines are nearly full, you may experience some "air pockets".
Allow these to escape before closing the cold water supply faucets.
6. Turn the appropriate (12-volt GAS or 120-volt ELECTRIC) storage water heater power
switch ON. Turn the water heater power switch. Water will be heated on demand.
Sanitize / Winterize Lines: This setting is typically used for drawing RV antifreeze into the
water lines of the motor home. When the fresh water tank drain and the low point drains are
closed, a siphon is created in the water lines allowing antifreeze to be pulled into the water
lines. This setting will not allow antifreeze into the fresh water tank. See Sanitizing/winter-
izing the Plumbing System.
Sanitize Tank: This setting is used to sanitize the fresh water
tank. When the fresh water tank drain and the low point drains
are closed, a siphon is created in the water lines allowing sani-
tizer to be pulled into the fresh water tank from an external con-
tainer. See Sanitizing/winterizing the Plumbing System.

Fresh Water Holding Tank

Direct access to fill the fresh water tank is typically located in the
sofa base. The exact location of the fill may vary depending on
the model. Remove the cap for direct filling of the water tank.
If needed, sanitize the water system prior to travel.
The fresh water tank can also be filled using the city tank fill set-
ting on the utility center.
To empty the fresh water tank, locate the drain valve under the
vehicle chassis close to the tank location. This will empty the
tank only. To drain the entire water system, the low point drains
must be used.
Do not cap, block or modify the fresh water tank overflow tubes in any
way. Enough water pressure can build up during the filling process to
damage the plumbing system if the overflow tubes are obstructed.
Be careful not to overfill the fresh water holding tank. It can pressurize
the tank, causing leakage and water damage and void the warranty. DO
NOT leave the tank unattended while filling.

Water Heater Bypass

Most models have a factory installed water heater bypass that enables you to avoid filling the
water heater with RV antifreeze. The 2-Valve Bypass is typically located in close proximity
