Basic Troubleshooting
To remove the hydrogen sulfide (rotten egg) odor:
1. TURN OFF your main water supply; that is, your pump or
your water hookup source.
2. DRAIN your water heater tank by removing the drain plug.
Approximately two quarts of water will remain in the bottom
of the tank.
◦ If the water drains slowly or sporadically (instead
of flowing freely), OPEN the Relief Valve to allow air
into the tank.
3. If the water still does not flow freely, take a small gauge
wire or coat hanger and push through the drain opening
to eliminate any obstructions.
4. AFTER completely draining the tank, FLUSH the entire
system with a solution of 2-parts vinegar / 1-part water,
from the water inlet all the way to the holding tank.
5. If you decide to use air pressure (55 PSI max.), it may be
applied either through the inlet or outlet on the rear of the
tank. It may also be applied through the Relief Valve port.
◦ First remove the relief valve. You may then insert your
air pressure through the relief valve support flange.
◦ With the drain valve OPEN, the air pressure will force
the remaining water out of the tank.
◦ If air pressure is unavailable, you may FLUSH the tank
with fresh water. Water should be pumped into the tank
with the assistance of the on board water pump or with
the assistance of external water pressure.
◦ External pressure may be pumped into the unit either
through the inlet or outlet found on the rear of the water
tank, or using the relief valve inlet located on the front
of the unit.
6. CONTINUE this flushing process for approximately five (5)
minutes allowing ample time for the fresh water to agitate
the stagnant water on the bottom of the tank and force the
deposits through the drain opening.
7. AFTER steps 1-6 (above) are complete, CLOSE the drain
plug and the Relief Valve. REFILL the tank with fresh water,
CIRCULATE, and RINSE.
If you use your vehicle frequently or for long periods of time,
flushing the water heater several times a year will prolong the
life of the water heater storage tank.
