Gray Water Holding Tank; Draining The Tanks - Jayco COVE 2002 Owner's Manual

GRAY WATER HOLDING TANK

No special preparation is required. However, placing a small quantity of chemicals into this tank,
such as baking soda or a Thetford chemical, will reduce odors from food particles in the system.
I
WARNING: We recommend that you DO NOT travel with waste in your holding
tanks. The weight of holding tank contents are not calculated into the cargo carrying
capacity of the trailer and the extra weight will greatly diminish the cargo weight
available to you, possibly causing you to exceed the gross vehicle weight rating of the
trailer. This can damage suspension components, such as springs, tires and axles. If
your model has the holding tanks located behind the axles, the weight of a full tank will
reduce the hitch weight. Sway and other handling difficulties can be the result of the
hitch weight being too light. If you are dry camping and cannot immediately empty the
tanks, use caution when towing and maintain lower speeds for better control of the
trailer until you reach a dumping station. Towing your trailer with one or more full or
nearly full holding tank(s), together with cargo you have added, may exceed the
GVWR of your trailer, causing towing difficulties and resulting in property damage
or personal injury.

DRAINING THE TANKS

On the outside of the trailer are labels (Fig. 4-13 & 4-14) that indicate the location of the gray and
black holding tank drain. A typical set up of the tank drain and termination valves is indicated in Fig.
4-15. Look for the labels to locate the drain and follow the instructions below to empty the tanks.
If you are hooked up to a sewer drain line on your lot, keep the termination valve on the waste tank
CLOSED until tank is at least 3/4 full. This will provide sufficient water to assist in complete
draining of tank. At this time, open the termination valve to empty the tank (see directions for
draining below) and close the valve when the tank is empty. Repeat this process as needed, but
NEVER leave the termination valve open when hooked up to the park's sewer system.
