One of the questions I see asked over and over is, “Can I dump my RV black tank at home?”

The answer is yes—if your home has a sanitary sewer cleanout and local regulations or HOA allow it.

For years, we would dump our tanks before leaving the campground and then spend the drive home hoping nobody needed to use the bathroom. If they did, it usually meant stopping at a rest area or gas station.

That all changed when I set up a simple home dumping system using my home’s sewer cleanout. Now, if someone needs to use the Casita bathroom on the drive home, we simply do. Once we’re back in the driveway, I dump the tanks at home on my own schedule.

In this guide, I’ll show you the exact setup I use, how it works, and why it has become one of my favorite additions to our camping routine.

Here’s my complete home black tank dumping setup before we dive into the details.

🔧 The Setup I Use

Our home has a 4-inch sanitary sewer cleanout located next to the driveway. Rather than making one last stop at a dump station before heading home, I can empty my Casita’s black and gray tanks right here in my own driveway.

My setup is simple:

• SewerSolution attached to the Casita’s sewer outlet.
• Standard garden hose supplies the water pressure.
• 3/4-inch PVC pipe carries the waste directly into my home’s sewer cleanout.

According to the manufacturer, the SewerSolution can pump waste up to 100 feet across level ground and up to 3 feet uphill, depending on water pressure and your specific installation. In my case, I use three 10-foot sections of 3/4-inch PVC joined together with standard PVC couplers, giving me about a 30-foot run from the Casita to my home’s sewer cleanout. The SewerSolution has had no trouble moving the waste that distance.

💧 Why I Chose the SewerSolution

After looking at the different ways to dump RV tanks at home, I decided on the SewerSolution, and I’ve been very happy with that decision.

What sold me was its simplicity. Instead of using an electric macerator pump with a motor to maintain, the SewerSolution uses ordinary garden hose water pressure to break up the waste and move it through the PVC pipe. There’s no electrical hookup, no motor to fail, and very little to maintain.

Another feature I really appreciate is the built-in rinse function. After the tanks are empty, I simply switch the valve and let the high-pressure water jet rinse the entire system before disconnecting everything. It leaves the hose and SewerSolution much cleaner before putting them away.

For my setup, it has been a simple, reliable solution that lets us keep using the Casita bathroom all the way home instead of planning our last few hours around the nearest dump station.
