2022 East to West Entrada Motorhomes Waste Water System Owners Manual

WASTE WATER GENERAL INFORMATION

The waste water system in your RV can be described as two separate systems. A gray water system, which consists of the drain lines and holding tank for waste water from the sinks and tub, and a black water system, which includes the holding tank and drain for toilet wastes. Each system is self-contained and allows disposal of waste water at designated dump stations at your convenience.

Due to the vast array of floor plans and the necessary rearranging of plumbing systems, locations will alter, but in general, the holding tanks are located approximately beneath the bathroom and kitchen areas. Drain valves and drain hose storage are usually located on the driver’s or off-door side of the unit.

UNPLEASANT ODORS

Components of the gray water system have drain traps and all tanks are vented to equalize air pressure and disperse odors to the outside. Residue in the drain water lines and black waste tank can also produce odors. To combat water holding tank odors, an RV approved deodorizing agent should be used. An agent that dissolves grease and fats and contains a detergent will help keep the tanks and lines clean and free flowing. You can obtain the deodorizer at most campgrounds and at stores that carry camping supplies.

EMPTYING THE HOLDING TANKS

Each holding tank has a drain line and dump valve, which permits dumping tanks individually or together. Each tank should be emptied often and ONLY at dump stations designated for this purpose. Dump stations can be found at most campgrounds and truck stops. Many service stations, particularly along interstate highways, also have these facilities. Campground directories list dumping station locations across the nation. If possible, dump holding tanks before a trip to reduce the gross vehicle weight. It is very important that you keep enough water in the black water tank to cover the bottom to prevent hardening of any waste residue that may remain. Never dump the black water tank until it is 3/4 full. (Check the tank level on your monitor panel.) This practice ensures that enough water is in the tank to flush all wastes into the sewer line. If necessary, fill the tank to the 3/4 mark with additional water before draining. Never put anything in the holding tanks other than normal drain water, body waste, and biodegradable products. Paper wrappers, gum, cigarettes, etc., no matter how small, should NEVER be placed into either the gray or black tanks as doing so could cause damage to your plumbing system and/or tanks.

If connecting to a campsite dump station sewer inlet:

• Do NOT open termination valves until tanks are 3/4 full.
• Do NOT keep black water valve open while parked.

To empty your holding tanks:

1. Make sure all sewer drain tank valves are CLOSED before removing the RV drain cap.
2. Remove the cap from the RV drain termination and connect the sewer drain hose.
3. Attach the other end of the flexible sewer drain hose to the dump station inlet. Be sure both ends of the flexible sewer drain hose are securely attached.
4. Drain the black water tank first by pulling the termination valve handle away from the valve body to the OPEN position. Be sure to allow sufficient time for the tank to completely drain.
5. Rinse the tank with several gallons of water by depressing the stool pedal, hand flush handle, or use the black tank flush, if equipped. CLOSE the valve on the stool and let it fill before releasing to the tank. This creates additional force to flush the tank more completely.
6. Drain the gray water tank by pulling the termination valve handle away from the valve body to the OPEN position. Draining the gray tank last uses the water in the tank to rinse the drain lines and flexible sewer drain hose.
7. When the tanks are empty, starting at the RV’s termination, “lift and walk” the remaining water out of the drain hose toward the dump station inlet.
8. CLOSE all of the termination valves by pushing the handles back to the closed positions.
9. Remove the flexible sewer drain hose from the RV drain termination and wash it thoroughly with clean water. Remove the other end from the dump station inlet and replace it in its storage compartment.
10. Secure the sewer hose storage cover.
11. Replace the caps on both the RV outlet and the dump station inlet.
12. Never empty your holding tanks directly on the ground, a roadway, river, or stream.
13. ALWAYS clean up the dump site before leaving.

Solid waste often will not flush directly into the sewer system. Liquid waste typically drains the best. Therefore, you must allow water to accumulate in the black tank and give the chemicals time to break down the solids before emptying the tank. Always keep enough water in the waste tank to cover the bottom. Doing so will help prevent waste from solidifying, which will prevent the waste from being flushed from the system. If draining the gray water tank directly into the sewer inlet while parked, be sure to close the termination valve for a period of time before leaving, allowing water to accumulate in the tank for use in flushing the drain line and flexible hose.
