The water and your contributions flow down a tube and into your tank, whatever size it may be. Water you use in the shower or sinks goes into a separate holding tank for RV use. All the waste water stays in the trailer holding tank until you open the corresponding valve to dump it. This is what RV septic systems do.

How do I know if my RV septic tank is full?

There is another way to know your tank is full (or close to it) besides using sensors or sound. “Sound” is also a good indicator, but in addition to that method, the closer to full, the more it smells (even if you use chemicals). Youll want to dump for sure when you cant take the smell any longer.

How do I connect my RV to my septic permanently?

Typically, you will find a clean out is the easiest way to connect your RV to your septic tank. This will be a PVC pipe that comes out from the ground with a screw cap. You can simply remove the cap and attach the sewer hose from your RV into this clean out.
