Basic Troubleshooting
WASTE TANK
Waste tank (black) will not drain
• Buildup or debris in tank. Check for buildup in tank at
stool.
• Always use a minimum amount of biodegradable toilet
paper.
• Always use plenty of water when flushing.
• Check termination valve for proper operation.

Temperature-pressure relief valve weeping
• Weeping or dripping of relief valve while water heater

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 you notice during the draining
that the water is flowing sporadically or slowly, instead
of flowing freely, you should open your relief valve to
allow air into the tank.
3. If the water does not flow freely, take a small gauge
wire or coat hanger and push through the drain open-

4. After thoroughly draining the tank, flush the entire sys-
tem from the water inlet all the way to the holding tank.
To flush, use four parts vinegar mixed with two parts of
water. 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. In this case, it will be necessary to
first remove the relief valve. You may then insert your
