Fresh Water Tanks and Draining

Drain Valves

Under the trailer are galvanized steel boxes that are a
few inches lower than the trailer frame. These boxes
are insulated exterior tank pans and they support the
freshwater and holding tanks. Petcocks open with a 1/4
turn, line drain valves are open when the handle aligns
with the water line.

Drain Valve Locations

Nest has two water line lowpoint drain valves that are
located on the curbside in front of the tire behind the
black utility compartment.

Fresh Water Tank Draining

Pumping the water out with the self-contained water
pump can empty the fresh water tank. Simply turn on
the pump switch and open a couple of faucets until the
water will no longer drain out, or use the petcock-type
drain valve located on the freshwater tank pan. Be sure
to watch closely and turn the pump off when the tank
runs dry.
CAUTION
Do not let the pump run dry for extended periods of
time as this could damage the pump.

Water Heater Draining

Nest is equipped with Suburban's Nautilus On-Demand
water heater. This "tankless" heater features built-
in freeze protection. For more details, refer to the
manufacturer's owner's manual provided with your
trailer.

Water Heater Bypass Valve

The Nautilus On-Demand water heater bypass valve
is located on the backside of the heater. It can be
reached via the access panel below the curbside
dinette cushion or mattress. Simply turn valves to
bypass heater.

Sanitizing

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.
a. Multiply "gallons of tank capacity" by 0.13;
the result is the ounces of bleach needed to
sanitize the tank.
b. 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.
3. Pour the correct amount of solution (water/bleach)
into the Fresh Water tank and fill with potable
water.
4. Open all faucets (hot and cold) allowing the water
to run until the distinct odor of chlorine is detected.
5. The standard solution must have 4 hours of contact
time to disinfect completely. Doubling the solution
concentration will allow for contact time of one (1)
hour.
6. When the contact time is completed, drain the tank.
Refill with potable water and flush the plumbing of
all sanitizing solution.
