Gray Water Holding Tank; Waste Water Disposal - NewMar 2006 Mountain Aire Diesel Pusher User Manual

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.
WARNING
Holding tanks are an enclosed sewer system and must be drained into an
approved dump station. Both black and gray water holding tanks must be
drained and rinsed thoroughly on a regular basis in order to prevent the
accumulation of harmful or toxic materials.
Whenever possible, drain the holding tanks prior to traveling. The carrying
capacity of your unit will be reduced if water is left in the black or gray
tanks.
The holding tanks should only be drained when they are at least 3/4 full.
Doing this will provide sufficient water to allow the complete flushing
