All Suburban HWS’ have an anode
rod which absorbs all the corrosive
action of hot water. It is located on
the bottom of the HWS (under the
main burner), simply unscrew this to
drain the tank of water. If the rod is
mostly eaten away, replace it with
a new one. The Suburban anode
rod fits the 4, 5 and 6 gallon tanks.
Did you know?
There are many anode rods on the market. Cheaper imitations
may not always be the best fit for a Suburban HWS. Not only
are some imitations the incorrect length, you also need to be
weary of the thread type (at the head of the rod). The Suburban
range of HWS’s are made in the USA and they use the NPT
style threads. Most other parts of the world use a BSP style
thread. If a BSP threaded anode rod is fitted into a Suburban
HWS it will damage the rungs on the internal thread and cause
future leaks. Coast always recommends using a Suburban
anode rod in a Suburban HWS.

SUBURBAN NEW STYLE
POLAR WHITE DOOR
- suitable for SW6PA,
SW6DA, SW6DEA and
SW4DEA
Suburban exterior doors stand up to the elements and frequent
use, with corrosion-resistant steel finished in a tough, high-
solids baked enamel for extra chip resistance. Coast to Coast
stock the standard doors which are installed without bending
flanges or installing corner gussets for easy installation and a
superior seal.
Can I operate my water heater’s electric element & gas
burner at the same time?
YES - when taking advantage of available campsite or
generator-produced electricity you may operate on both gas and
electric for a faster recovery rate
Are all Suburban Water Heaters equipped with an Anode
Rod? What is its function? When should it be changed?
YES - all Suburban water heaters feature an anode rod. The
anode equalizes aggressive water action, providing
cathodic protection for the tank. It is a very important factor in
tank life & should only be removed for inspection, draining or
replacement. It is removable using a 1-1/16” thin wall socket.
Under normal use, the anode rod will deteriorate. Because
of this, we recommend it be replaced bi-annually or when
consumption or weight loss of the rod is greater than 75%.
Note: Water with high levels of iron &/or sulphate will increase
the rate of deterioration. To extend anode life, drain water from
tank whenever the RV is not being used. Avoid any extended
time of non-use with water in the tank.
Why does water drip from my water heater’s pressure &
temperature (P&T) relief valve?
You may experience water weeping or dripping from your water
heater’s pressure & 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 an RV is a closed system &
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.
Can I add-on an electric element to a PA/DA Model (GAS
ONLY Unit)? What will happen if I use it?
NO - the use of these aftermarket heating element devices may
result in damage to components or the water heater. When
aftermarket heating elements are inserted into the anode
rod/drain connection, tank life is shortened by accelerating
inner tank corrosion. This will be a non-warrantable situation.
An upgrade is required to a GAS/ELECTRIC model, for this
application.
