Here are some of the things you need:

  • Water softener
  • Any brand of laundry detergent
  • Measuring cup
  • Bottle
  • Boiling water
  • Drain cup

Instructions:

Step 1 – Get a hose. The black holding tank flushes into a campground waste water system via a 3-inch, 10- to 20-foot heavy duty sewer hose.

Step 2 – Close the black water valve and remove the sewer cap. The large valve is for the black water holding tank and the small valve is for the gray water holding tank.

Step 3 – Place the hose adapter by placing it over the outlet of the tank drain. Use a sewer hose support to achieve a good holding angle as you position the hose. Make sure the seal is tight before proceeding. Turn the adapter clockwise to secure.

Step 4 – Carry the other end of the sewer hose over to the campground sewer connection. It’s important that you carry the the hose to prevent tearing and other damage.

Step 5 – Flush the tank with water. Use the reverse flush valve that connects directly to your sewer outlet to clean the black water holding tank.

Step 6 – Soften your newly cleaned black water holding tank. Combine water softener and hot water. Add 2 cups of water softener to 1 gallon of hot water. Allow several minutes for the water softener to dissolve.

Step 7 – Close the drain valve, which is located on the bottom of the tank.

Step 8 – Pour the solution down the black water holding drain. Empty the tank before pouring the solution inside.

Step 9 – Use a drain pan to drain the black water holding tank. Pour 1 additional cup of laundry detergent inside the black water holding tank to complete the flushing process.

So make it a habit of keeping your RV tanks clean and sanitized to have a more enjoyable RVing experience.
