Add 1 full quart
to the tank and fill the tank with water. Let it sit a MINIMUM of one week
; then dump and rinse for a MINIMUM of 30 minutes (by the clock)
For severely clogged tanks, this process should be repeated.
Once done and water running free and clear, prevent future problems by adding 1/2 cup liquid Calgon water SOFTENER and 1/2 cup liquid detergent to 5 gallons of water before you use the black tank for waste.
NEVER use the tank for solids when it has no water in it.
