How to Empty Portable Waste Tank and Where?

Emptying the black tank from your RV will ensure your vehicle is waste-free. Luckily, it is not that difficult to do. The first thing to do is tow your RV to a dump station. Your objective is to bring the sewage outlet closer to the landfill. Wear your disposable gloves and check the septic tank’s valve to make sure it is fully closed.

The next thing you need to do is connect your RV’s sewer pipe to the correct outlet. Be sure to connect it to the specially designed sewage tank for black water. Additionally, the pipe must be secured with an additional hose clamp.

The next step is to take the other end and then use a pipe elbow as a way of connecting to the discharge. This step facilitates the connection of the pipes, minimizing or avoiding the risk of spills. Release the tank’s valve after tightening everything.

As you do this, you will hear the waste spill. Keep it flowing until there is no more sound from doing this. The next step is to flush the toilet several times to make sure all the wastes have been cleaned. Then rinse the gray water tank.

Once you’re done, you can fill both water tanks (gray and black) with water and then rinse them again in case you want to rinse them thoroughly. The next step is to close the gray and black water drain valves. Next, you need to reconnect the plumbing to your RV. Connect the dump hose to the storage area. Move your RV out of the area and use chemicals or enzymes designed to treat the septic tank.
