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

Water Heater

Nest is equipped with Suburban's Nautilas 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 Nautilas 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.
Nest requires about 3 ounces of common household chlorine
bleach combined with a FULL tank of fresh water to sanitize its
tank.
Systems with new components, or ones that have been
subjected to contamination should also be disinfected as follows:
1. Pour ~ 3oz of chlorine bleach into the fresh water tank and
completely fill with potable water.
2. Open all faucets (hot and cold) allowing the water to run until
the distinct odor of chlorine is detected; then close valves.
3. Let the solution stand for a set time. Typically, the standard
solution must have 4 hours of contact time to disinfect
completely. Doubling the solution concentration (~6oz) will
allow for contact time of one hour.
4. When the contact time is completed, drain the tank. Refill
with potable water and flush the plumbing of all sanitizing
solution.

Waste Water System

Waste Water Tank Dumping

To empty waste water tank, remove outlet cap and attach the
sewer hose by pressing the hose bayonet inlet fitting onto the
outlet — rotating clockwise until it feels solid and secure. Attach
the outflow end of the hose to the sewage station and orient
hose so it will completely drain. Pull the dump valve handle out
and wait until the tank is drained.
Close the dump valve and partially refill the tank with clean water
and repeat the process until clean. The holding tank must be
flushed out until all paper and waste material is removed. Should
solids accumulate, close the dump valve, fill the tank about half
full with water, then tow the trailer for a few miles. The turbulence
caused within the tank will usually loosen and suspend the solids
so the tank can be drained. Replace the dump outlet cap prior to
traveling.
When you are in a park and connected to a sewer station, keep
the main holding tank dump valve closed, and empty waste tank
every few days or when it becomes almost full. Only by sending
a large volume of liquid, all at once, through the main holding
tank will toilet paper and other solids completely wash away. This
practice will avoid the accumulation of solids in the waste holding
tank, which could lead to an unpleasant cleaning job.
Draining the tanks as described will protect them from freezing
during storage. When traveling in sub-freezing temperatures, use
a winterizing solution designed for RV use. Follow the directions
on the container.

Waste Water Tank Flush

The trailer has a water hose connector
specifically for flushing the waste water
tank. To use, hook up a garden hose and
turn it on. A spray head within the tank
will rinse the interior surface of the tank.
The dump valve should be closed for the
first couple of minutes. Once the tank is
half full, turn the hose off, pull the dump
valve and release the water out in a rush.
Repeat as needed. The tank flush should
be used regularly or the spray head may
become clogged.
