SECTION 7 –
PLUMBING
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 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.
• Chlorine may be removed from drinking
water by the cold water filter at the galley
faucet or by the separate filtered water faucet
(if equipped).
• Superchlorination does not affect city water
usage, only the fresh water tank.
COLD WATER FILTER
–If Equipped
To obtain filtered cold water for drinking or
cooking, simply open the galley sink cold water
faucet.
NOTE: Only the cold water faucet is filtered.
The cold waterline flows through an activated
carbon filter that removes chlorine and odors for
taste-free drinking water.
Replacing the Cold Water Filter
Cartridge
You should replace the filter cartridge every
season and when water flow from the faucet is
too slow for convenience. The cartridge must be
replaced at least every 12 months.
• Place a container beneath the filter to catch
any water remaining in the waterlines during
filter removal.
Chlorine is poisonous. Do not misuse.
Recap bottle and clean all utensils after
use.
