PLUMBING SYSTEMS
and temperature (P&T) relief valve when your
water heater is operating. Water weeping or
dripping does not mean that the P&T valve is
defective. As water is heated, it expands. The
water system in a RV is a closed system and
does not allow for the expansion of heated
water. When the pressure of the water system
exceeds the relieving point of the P&T valve,
the valve will relieve the excess pressure.
One way to reduce the frequency of this
occurrence is to maintain an air pocket at the
top of the water heater tank. This air pocket
will form in the tank by design; however, it will
be reduced over time by the everyday use of
your water heater. To replenish this air
pocket:
3. Turn off the water heater.
4. Turn off the cold water supply line.
5. Open a faucet in the RV.
6. Pull out the handle of the pressure relief
(P&T) valve and allow water to flow from
the valve until it stops.
7. Release the handle on the P&T valve - it
should snap closed.
Close the faucet and turn on the cold water
supply. As the tank fills, the air pocket will
develop. Repeat this procedure as often as
needed to reduce the frequency of the
weeping P&T valve.
Anode rod protection
The tank in the Suburban 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 OEM 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 then 75 percent.
Fig. 5.10 Suburban anode rod replacement chart
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 tank protection.
Operating the water heater without the proper
anode rod protection will decrease tank life
and will void the vendor warranty on the tank.
Do not replace the 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.
Maintenance
Do not allow the burner to burn with a yellow
flame, because sooting will occur. Do not
continue operating the water heater with an
improper burner flame. Periodically, inspect
the water heater for soot. If soot is present
anywhere on your water heater, immediately
shut the unit down and contact your dealer or
a qualified service agency. Soot is a sign of
incomplete combustion and must be corrected
before operating the water heater.
Draining the water heater
The Suburban water heater tank is drained by
removing the anode rod (an Atwood water
heater is manufactured differently and it does
not have an anode rod). To extend anode life,
drain water from the water heater tank
whenever the RV is not being used. Avoid any
