SECTION 7 –
PLUMBING
2. Turn water pump switch to “OFF” position.
3. Fill water tank.
4. Open all faucets, hot and cold.
5. Turn on water pump switch.
6. Close each faucet as it begins to deliver a
steady stream of water (close cold water first).
Leave hot water faucets on until they also
deliver a steady stream of water. This will
ensure that the water heater is filled with
water.
7. Check to be sure pump stops soon after all
faucets have been closed.
8. Pump is now ready for automatic operation.
Pump will start when a faucet is opened and
stop when the faucet is closed.
DISINFECTING YOUR FRESH
WATER SYSTEM
To ensure complete disinfection of the potable
water system, it is recommended that the
following procedure be followed on a new
system, one that has not been used for a period of
time, or one that could have become
contaminated.
This procedure is also recommended before
long periods of storage such as over winter.
1. Prepare a chlorine solution using 1 gallon of
water and 1/4 cup of household chlorine
bleach (sodium hypochlorite solution). With
tank empty, pour chlorine solution into the
tank. Use 1 gallon solution for each 15 gallons
of tank capacity. This procedure will result in
a residual chlorine concentration of 50 ppm in
the water system.
If a 100 ppm concentration is desired as
discussed in Step 4, use 1/2 cup of household
bleach with 1 gallon of water to prepare the
chlorine solution. One gallon of this solution
should be used for each 15 gallons of tank
capacity.
2. Complete filling of tank with fresh water.
3. Open each faucet in the coach and run the
water until a distinct odor of chlorine can be
detected in the water discharged. Do not
forget the hot water faucets.
4. Let the system stand at least 4 hours when
disinfecting with 50 ppm residual chlorine.
(If
a shorter time period is desired, then a 100
ppm chlorine concentration should be
allowed to stand in the system for at least 1
hour.)
5. Drain the water tank and refill with fresh
water.
6. Open each faucet again and run fresh water to
flush chlorinated water from the lines. Run the
water until there is no odor of chlorine
detected in the water discharged. Do not
forget the hot water faucets.
(
You may need to leave a hot water faucet
open for some time to flush the water heater
with clean water. You may also want to turn
the water heater off until this is done to avoid
wasting energy trying to heat “unused”
water
).
7. Water system is now disinfected.
Continuous Tank Disinfection
(Superchlorination)
Some RVers like to ensure continuous
sanitation of their fresh water tank by
“superchlorination”– maintaining an effective
low level of chlorine in the tank at all times.
•
Add 1 teaspoon of household chlorine bleach
(sodium hypochlorite) to your tank for each
10 gallons of tank capacity. When you fill the
tank, this will result in a 6.7 ppm level of
chlorine, which should kill harmful bacteria
and slime-forming organisms.
WARNING
Chlorine is poisonous. Do not misuse.
Recap bottle and clean all utensils after
use.
