The cleanest, most sanitary and convenient way to empty your RV holding tank!
Finally a way to empty your holding tanks (unquestionably the most distasteful job in RVing) that everyone in the family will find easy to use.

Thetford's Sani-Con System does not rely on gravity. Utilizing a heavy-duty transfer and macerating pump, the unit works much like a household garbage grinds and liquefies black water waste*, then pumps it through an extra heavy duty 1" diameter discharge hose.

The powerful macerating pump can pump waste UP terrain, UP into a backyard sewer cleanout, UP into a household toilet, UP into an elevated sewer dump station, etc. No need for a constant slope or cumbersome hose supports. That means less handling and an easier method to empty the tanks.

Sani-Con features a long-lasting 1" discharge hose that stretches up to 21 feet, than retracts to a convenient 7 feet to save storage space - more than 80%!!

At the end of the hose is an easy-to-use threaded nozzle that is designed to fit securely (lock) into a variety of dump station inlets, keeping you clean and ending the need for additional adaptors.

The nozzle has a screw on cap that really keeps the entire operation easy and clean. The cap prevents drips and spills during storage, making the unit more sanitary and less odorous than the old style 3" diameter sewer hoses.

Sani-Con Twist-On System has a 21' retractable discharge hose with sewer nozzle and cap. Wiring included.

*human waste, liquids and toilet tissue ONLY.

To use the system:

  • Connect the macerating pump (Twist-On and Tank Buddy only)
  • Extend and insert the nozzle into the dump station
  • Open the black water slide valve
  • Turn on the Sani-Con pump
  • When the black water tank is empty, turn off the pump, close the black water slide valve, open the grey water slide valve, and turn the pump back on
  • When the gray water tank is empty, turn off the pump, close the gray water slide valve, put the screw on cap onto the nozzle and return the nozzle and hose to storage

This system works very well at home to empty the tanks. It is easy to clear any material that will not go through the pump. I have been using it on 75' of 3/4 hose. I think it is the best system for home use. No more hunting a dump station on the way home and worrying about filling the tanks while parked at home. We are using our trailer while remodeling our home.

I had Camping World (Tampa) install this unit in January, and I wanted to use it for awhile before submitting my review. So, we have used it now several times and I am very happy with it. When we first got it, I was a little concerned because it evacuated the black tank in a more orderly way than the whoosh (!) I was used to with the 3" hose. I wondered if the flow of the Sani-Con was enough to completely empty the tank. The flip side of that, though, is that I don't have to worry about the 3" hose trying to fly out of the drain and spray everywhere like in the movie RV! In the past, with the 3" hose, I would look for a rock or something heavy to hold the hose down when I opened the dump valve (sometimes my wife's foot had to serve this purpose!). With the Sani-Con, it is a very easy, very clean process. I would recommend it to anyone. There are 3 different applications (models), so make sure you get the one you want. I wanted the "box mount" and they installed the "twist on" by mistake, but I have been happy with that anyway.

This was a replacement for an 8 year old Sani-Con that I had worn out. I was extremely pleased with the cleanliness and ease of operation of the previous system and didn't consider any other product.
