Low Point Drains
To drain hot and cold lines:
1 . Open hot and cold low point drains .
2 . Open the shower handle and faucet until all
water has drained from the lines .
troubleshooting the
Fresh Water System
Water system problems usually fall into two
categories: Inherent system problems, and
problems caused by neglect . System problems
are usually the result of road vibration and
campsite water pressure variations . Problems of
neglect usually stem from failure to clean filters,
improper winterization, and poor battery main-
tenance . Most water system problems can be
avoided by conscientious maintenance .
Leaks
Vibration, flexing and twisting while traveling
can work pipe fittings loose. Check all plumbing
for leaks at least once a year . If the water pump
runs when a faucet is not open, suspect a leak .
Be sure the tank drain valves are tightly closed .
Leaks occur most often around threaded fittings.
If necessary, tighten or clean and tighten the fit -
tings. Do not overtighten fittings. Connections at
galley and lavy fixtures should not be tightened
with a wrench . They will normally seal with
hand-tightening . If a leak persists at one of the
fittings, disconnect it completely and check for
mineral deposits or other foreign matter at the
seating surfaces . Clean the surfaces thoroughly
and reinstall the fitting.
Connections at the water tank, pump and valves
are made with special clamps . They can be
replaced with standard automotive type hose
clamps .
Leaks caused by freezing damage can be pre-
vented by proper winterization of the system .
See the Storage chapter of this manual . Freezing
damage is usually extensive and may
include a burst water tank, split piping, and a
damaged water pump, toilet, and water heater .
If you experience this type of damage, repairs
can best be made by an authorized Fleetwood
dealer .
For your safety, the shower faucet is equipped
with a vacuum breaker device . This device is
designed to prevent backflow of water into the
fresh water system, reducing the possibility of
contamination of the water supply . When the fau-
cet is in the OFF position with the shower hose
held above the faucet, water will drain out of the
vacuum breaker . This drainage is not a defect, but
indicates that the faucet is working correctly .
Sanitizing the Fresh Water System
As approved by the U .S . Public Health Service,
sanitize the fresh water tank and piping system
whenever the system may have become contam-
inated, has not been used for a period of time,
or before long periods of storage . This will dis-
courage the growth of bacteria and other organ-
isms that can contaminate the water supply . Use
a chlorine/fresh water rinse as follows:
1. Prepare a solution of 1⁄4-cup household
liquid chlorine bleach (5% sodium hypo-
chlorite) to one gallon of water . Use one
gallon solution for each 15 gallons of tank
capacity .
2 . Close drain valves and faucets, pour the
chlorine solution into the exterior fresh
water tank filler spout, and complete filling
at tank with potable water .
3 . Turn water pump switch ON . (Be sure you
have 12-volt DC power .) Open all faucets
individually until water flows steadily, then
turn them off . This will purge any air from
the lines .
4 . Top off water tank with fresh water and
allow the system to stand for at least 4 hours .
5 . Drain the entire system by opening all
potable water tank valves, plumbing line
drain valves, and operating faucets .
