Jayco Alante 2023 Black and Grey Tank Drains User Manual
Black and Grey Tank Drains
There are labels on the exterior of the recreation vehicle indicating the location of the grey and black tank drains (also called dump valves). Depending on your model, you may have one or two valves. With one valve, the gray and black tank will release contents simultaneously. With the 2-valve set up, it is recommended that you release the black tank first, followed by the grey tank. This will help rinse and debris from the outlet and sewer hose. To make drainage easier, level the RV.
- Remove the sewer hose housing dust cap and attach the sewer hose (customer supplied).
- Place the end of the sewer hose into the approved dump station.
- Open the black tank dump valve (depending on your model the valve may be located under the RV, or on the utility center). Close the dump valve when the black water holding tank is empty.
- Open the grey tank dump valve (depending on your model the valve may be located under the RV or on the utility center). Close the dump valve when the grey holding tank is empty.
- Remove, clean and store the sewer hose.
- Close the sewer hose housing dust cap.
You can locate dump stations throughout the United States and Canada in Woodall’s, Rand McNally Camp Guide, Good Sam Camp Guide, KOA Kamp grounds Camp Guide and various other publications. Some fuel stations also have dump stations. Please contact your RV dealer for assistance in the purchase and installation of a sewer hose or sewer hose extension (if needed).
Sewage (black) tank preparation
It is important to add enough water to prevent solid waste buildup. Follow the directions listed below and in the manufacturer’s operator manual.
- Release one to two quarts (1 or 2 liters) of water into the toilet bowl.
- Follow the directions on your RV-approved toilet chemical bottle (customer supplied) and put the recommended quantity of holding tank chemicals into the toilet bowl.
- Flush the toilet and allow at least two gallons (8 liters) of water to flow into the holding tank.
Waste (grey) holding tank preparation
No special preparation is required, however, placing a small number of chemicals into this tank, such as baking soda or an approved RV chemical, will reduce odors from food particles in the system.
Cleaning and Maintenance
The toilet should be cleaned regularly for maximum sanitation and operational efficiency. Use only RV approved chemicals. Do not use chlorine (undiluted) or caustic chemicals, such as laundry bleach or drain opening types, in the toilet system. These products damage the seals in toilets and dump valves.
Black Tank Flush
The black tank flush (no fuss flush) inlet is typically located on the utility center panel (if so equipped) labeled as “Tank Flush”. For models not equipped with a utility center, the inlet is located on the side of the recreation vehicle. The location may vary depending on your model. Attach a garden hose (connected to a pressurized fresh water source) to the black tank flush inlet. The water goes directly into the black water holding tank sprayer connection, allowing you to remove debris and prevent accumulation. A check valve is incorporated in the plumbing lines to prevent backflow. Flush the black water tank each time the grey and black water holding tanks are dumped or as needed.
Utility center (if so equipped) valve positions do not affect the tank flush function. It does not matter where they are positioned when operating the tank flush.
To help ensure debris does not clog the tank sprayer orifices, use “TANK FLUSH” every time the waste holding tank is emptied.
- Dump the black water tank (see Gray Tank Drain & Black Tank Drain) and leave the black tank drain valve open.
- Connect a garden hose from the water supply source to the black tank flush.
- With the water source turned ON, flush the black water holding tank until the water running out of the black tank drain valve is clear (not discolored or cloudy).
- Disconnect the garden hose and close the black tank drain valve. Fasten the sewer hose housing dust cap back on the tank flush inlet.
- The black tank drain valve must be OPEN any time there is a hose (water supply) connected to the black tank flush.
- Do not leave any hose (water supply) connected to the black tank flush when it is not in use.
Do not use the same hose to fill your fresh (potable) water tank that is used for the black tank flush.
