12 Volt DC Demand Pump
When water is desired and you are not hooked up to city water, you need to turn on 12
volt DC power to start the demand pump. Fig. 4-4 shows a typical demand pump set up.
Depending on your travel trailer model, the demand pump will be located under the bed,
in a cupboard, or under the sink. The switch to operate the pump (Fig. 4-5) is located on
the monitor panel or a wall near the pump. Energy for the pump is supplied by the
auxiliary battery or converter. The pump will self prime when started and provide water
for your travel trailer. The pump continues to run until approximately forty pounds of
pressure is achieved and automatically starts again when pressure drops to twenty
pounds. Some cycling in the pump may occur, depending on the volume of water being
released. A check valve is built inside of the pump to prevent water from flowing into
supply tank.
Note: The water pump switch should be in the off position when the camper is left
unattended for any amount of time. If something would happen to the water
system, this will ensure that water damage will be restricted to a small area.
Sanitizing and Filling the Potable Water System
Potable water systems require periodic maintenance to deliver a consistent flow of fresh
water. Depending on use and the environment the system is subject to, sanitizing is
recommended prior to storing and before using the water system after a period of storage.
Systems with new components, or ones that have been subjected to contamination,
should also be disinfected as follows:
1. Use one of the following methods to determine the amount of common household
bleach needed to sanitize the tank.
• Multiply “gallons of tank capacity” by 0.13; the result is the ounces of bleach
needed to sanitize the tank.
• Multiply “liters of tank capacity” by 1.0; the result is the milliliters of bleach
needed to sanitize the tank.
2. Mix the proper amount of bleach into a container of water.
