Recreational Vehicles, otherwise known as RV’s, have two waste water holding tanks. The gray water tank holds the waste water from your sinks and showers while the black water tank holds the waste from your toilet. To maintain your RV, you need to dump and clean the waste water tanks on a regular basis while using and especially when preparing the RV for storing.
Connect your black water tank to the dump station by using an RV sewer hose. There is usually a cap on your RV that will have to be unscrewed before the sewer hose is connected. The sewer hose is a flexible hose that is available at any RV supply store or department store. This flexile hose allows for a quick and leak-proof connection to the dump station. Be sure both ends are secured before proceeding. Both the black water and gray water tanks are drained through the same hose connection with each having a separate butterfly style valve. Always start with the black water holding tank.
Open the butterfly valve to release the contents of the black water holding tank. You should be able to hear the waste water draining from the tank. While the black water is draining, connect the fresh water hose to the spigot and to the inlet for flushing out the waste water tanks. When the sounds of the running waste water has diminished to a trickle, turn on the fresh water valve to clean the black water tank. Allow it to run for a few minutes, about three minutes should be enough. Do NOT close the butterfly valve as you do not want to accidentally overflow the tank and flood your camper.
Turn off the fresh water valve and allow the black water tank to drain completely.
With the fresh water turned off, open the butterfly valve to allow the gray water to empty from the holding tank. When the tank has finished empting, leaving the butterfly valve open, turn the fresh water connection back on to allow it to flush as you did the black water tank.
Turn off the water and allow the gray water tank to continue to drain.
Disconnect the fresh water hose from both the inlet and the faucet. Close the butterfly valve to the gray water tank.
Disconnect the flexible sewer pipe from the RV waste water holding connection. Hold the hose at a high enough level to drain any remaining water into the dump station. If desired, use the fresh water hose to rinse the flexible sewer pipe. Disconnect the flexible sewer pipe from the dump station and the hose from the fresh water spigot. Store both away until the next use.
Add the recommended amount of the waste water deodorant product to the holding tank. Pour the product into the toilet bowl and add the recommended amount of fresh water. Use products that have natural enzymes to help break down future waste water.
