SECTION 8 - PLUMBING SYSTEMS
Odor from the hot water system
Many water supplies contain sufficient amounts of sulfur to produce an odor, often
called "sulfur water." Sulfur water can be caused by a chemical action or by
bacteria. Generally, sulfur water is not harmful, only unpleasant to smell. Refer to
the water heater manufacturer's owners manual for details on eliminating the odor
from sulfur water. Odor from sulfur water is not a service problem.
Do not replace anode rod or any other component with an accessory part that
is not authorized by the water heater manufacturer, such as an "add-on
electric heating element. Such items are not approved to be installed and
could create an unsafe condition and will void all warranties
Anode rod protection
The tank in the water heater is protected by a magnesium or aluminum anode to
prolong the life of the tank by absorbing the corrosive action of hot water.
Under normal use, the anode rod will deteriorate and because of this, the water
heater manufacturer recommends the anode rod be replaced yearly. Water with
high levels of iron and/or sulfate will increase the rate of deterioration; therefore,
more frequent replacements may be required.
If an anode rod is mostly eaten away, replace it with a new one.
The water heater manufacturer recommends replacement of the anode rod when
consumption or weight loss is greater than 75 percent.
Operating the water heater without the proper anode rod protection will decrease
tank life and will void the tank manufacturer's warranty on the tank. To extend the
anode life, drain the water from the water heater tank whenever the RV is not
being used. Avoid any extended time of non-use with water in the tank.
To prevent a water leak when replacing the anode rod, a pipe thread sealant
approved for potable water (such as Teflon Tape) must be applied to the threads
of the anode rod. Proper application of a thread sealant will not interfere with the
anode's
High altitude deration
Operation of the water heater at high altitudes may require derating. If the water
heater is not properly derated, lack of sufficient oxygen for combustion may
produce improper burner operation. Pilot outage caused by burner lift-off or
sooting from a yellow burner may occur, indicating the possibility of carbon
monoxide.
You may also notice a lack of efficiency in heating the water because of
incomplete combustion of the burner at these higher altitudes.
