Camping With Sewer Hook-Up
When camping at parks with sewer hook-up, it is
important to keep the black water holding tank gate valve
closed at all times, except when dumping. The gray tank
can be kept open while hooked to a sewer connection,
but the black water tank must be kept closed. This is done
so that an ample supply of liquid remains in the tank to
provide a smooth flow through the gate and drain valve
when dumping.
Su
ffi
cient liquid in the tank causes a swirling action
that should take any accumulated solid wastes with it.
Accumulation of solid wastes in the black water tank
can be avoided by keeping the gate valve closed when
connected to the sewer hook-up. If the valve is left
open, solid wastes may accumulate in the tank. This may
eventually result in costly repairs.
Holding Tank Rinse - No Fuss Flush
This article provides an overview of the holding tank rinse - no fuss flush. The coach may be equipped with a flushing
system for the holding tank(s).
On coaches equipped with tank rinse low point drain(s),
turning the tank rinse drain valve to the “open” position
will remove pressure and drain the tank rinse line. When
finished using the tank rinse, it is recommended to turn
o
ff
the water supply to the tank rinse connection. Open
the valve, and drain o
ff
the pressure in the line before
disconnecting the water hose.
CAUTION
!
Do not use the same hose for the No Fuss Flush that
is used for filling the fresh water tank. The gate valve
to the sewage tank must be in the OPEN position
while rinsing with the No Fuss Flush system.
Always drain the sewage tank prior to rinsing. Never
rinse a sewage tank that is full. The sewage drain
must be open while rinsing the sewage tank, and
the drain hose must be positioned to drain into an
approved sewage dump station. Failure to open the
valve will cause the sewage tank to fill with water,
and can cause damage to your plumbing and interior.
IMPORTANT
!
The basic tank rinse system consists of a water inlet, a
vacuum breaker (normally located in a lavatory cabinet
to provide placement of the vacuum breaker above
the height of the tank), a fixed sprayer in the tank, and
connecting water lines. When draining your sewer tank,
attach a water hose to the sewer spray hookup. After the
tank is drained, leave the gate valve open, and open the
water valve to allow water to spray inside the sewage
tank.
Allow the water to rinse the tank for a minimum of three
to five minutes to ensure it is clean. This should flush the
inside of the tank of any debris that may be left inside.
Next, disconnect the freshwater hose and close the gate
valve. If there are any solids still left inside the tank, fill the
sewage tank with approximately ten gallons of water and
holding tank chemical through the stool. As you travel, the
agitation of the water should help liquefy any solids left
in the tank. You can dump the sewage tank again at your
next destination.
Select coaches may also have a tank flush on the grey
water tank. Follow the same flush procedure by leaving
the grey tank gate valve open while flushing.
