Black Water Holding Tank; Gray Water Holding Tank; Waste Water Disposal - NewMar Scottsdale Class A 2006 Owner's Manual

Black Water Holding Tank

The black water, or sewage, holding tank is located directly beneath the toilet.
Before using the stool, you will need to treat the tank with water that is mixed
with an odor controlling chemical. These chemicals are readily available at any
RV supply store. Be careful not to spill the chemical on your hands, clothing,
or the carpet because it may cause a permanent stain. Pull the toilet levers
forward to allow the chemical to mix with the toilet water. Continue pulling
the toilet levers until at least one inch of solution is directly under the toilet.
Release the levers, and the waste tank is ready for use.
CAUTION
Use only approved RV odor controlling chemicals in the holding tanks. Products
containing ammonia and petroleum will damage the ABS plastic holding tanks
and seals.

Gray Water Holding Tank

The gray water holding tank is located in the underbelly of the unit. It is
primarily used for the drainage from the kitchen and bath sinks and the
shower.

Waste Water Disposal

Both of the holding tanks terminate in a valve arrangement that permits
draining each tank separately or together. It is recommended to drain the black
water tank before the gray water tank. This will allow the water from the gray
tank to wash the black water residue from the drain lines and hose. The valves
that open to release the water are called gate valves. The blade that closed the
opening in the sewer drain pipes is connected to the T-handle to release the
contents of the tank(s) when pulled. The sewer line must be securely capped
during self-containment use to prevent leakage of waste material onto the
ground or pavement. Do not pull the holding tank gate valve open when the
protective cap is installed on the pipe. Always drain the tank into an acceptable
sewer inlet or dump station.
