How good of a job does my black tank flush system do?

Your RV’s black tank flush system sprays water in a “set” pattern at approximately 100PSI-150PSI (due to the reduction in hose size and spray nozzle opening). While this is better than nothing, it doesn’t have enough force or volume to remove the sticky waste on the surfaces of your tank, nor can it adequately remove build-up against the front (downslope) wall of your tank, where waste collects.

That being said, be sure to turn on your black tank’s flush system while emptying the black — the extra turbulence from the flush system will help to move waste out of your black water holding tank.

The only way to get your holding tanks truly “factory kleen” is through the process of extremely high (1500PSI) water pressure and the continued use of adequate water usage and a tank solution to keep them that way.
