The Complete Guide To Treating Your RV Toilet

Treating your black tank correctly is simple and ensures your system remains clog and odor-free when you use RV Digest-It. There is a lot of misinformation out there regarding the best ways to treat your tank, so we’ve developed this easy to follow step-by-step guide so you can effectively treat your black tank without worry. Happy Camping!

  1. Dump your black tank
  2. Back-flush your black tank - If your RV is equipped with a back-flush system, run the back-flush until only clear, fresh water can is coming out of your discharge hose. For some, this can take 30 minutes (or more) depending on your RV’s system, the dump station fitting, and how level your RV is. Don’t be fooled. You may start to see clear water coming out of the tank and assume your tank is clean. Keep flushing for another few minutes. Often, a second wave of waste will flush out that has collected in the corners of the tank. If your RV isn’t equipped with a back-flush system, run fresh water (or gray tank water) following your tank-dump to flush out the residual waste in the discharge hose.
  3. Close your black tank valve
  4. Add several inches of water to your toilet bowl
  5. Shake RV Digest-It thoroughly before each use. Bacteria settles over time and needs to be mixed up before each treatment so that the correct amount is used per treatment.
  6. Pour 2 ounces of RV Digest-It into your toilet (4 ounces for the initial treatment)
  7. Flush your toilet
  8. Add several inches of water to your toilet bowl. You’re done!
  9. Repeat each time your dump your tank. To ensure your waste is being properly digested and odors are controlled, treat your black water holding tank following these instructions after each dump. You will only need to use 2 ounces of RV Digest-It per treatment after the initial treatment.


Follow These Rules To Effectively Remove Odors And Clogs

  • Back-flush your tank for 20 to 30 minutes every 5 to 10 dumps to maintain working sensor probes and to ensure no residual waste is collected in the corners of the tank that can lead to clogs or odors.
  • Always keep your black tank valve closed except when dumping your tank.
  • Always keep several inches of water in your toilet bowl when the RV is stationary to keep tank gas from backing up into your RV.
  • Always flush your toilet with an ample amount of water to ensure the microbes that keep your tank waste and odor free are well hydrated and tank temperatures are kept below 85 degrees.
  • Keep your tank temperatures down. If your tank gets too hot the bacteria will begin working less efficiently. We recommend adding water or ice if you believe tank temperatures are exceeding 85 degrees.
  • We recommend dumping your holding tanks every 4-5 days to keep odors diminished.
  • Never clean your RV toilet bowl with chemical toilet cleaners. These will kill the good bacteria that keep your black tank clog and odor free. Use a bacteria-infused toilet bowl cleaner, like Unique Toilet Cleaner.
  • After every dump, treat your tank with a bacteria-based tank treatment like RV Digest-It to ensure your tanks remain clog and odor free.
