Black Tank Flusher

The reason for that 'Caution' is mfg. lawyers covering their behinds......someone leaves valve closed and floods inside of rig.

I dump, then flush/rinse using OEm flush system with drain open then I close the drain valve and let the flush system flow. After about 5 mins I open drain valve and let the higher volume/level go whoosh. Then close the valve wait 30 seconds or so and shut down flush system (puts a few gallons or so of water back in tank for next time)

Then I dump grey tanks and pack up.......done

i agree, so far this is basically the way I do it, but instead of about 5 minutes once, i do it about 3 times for about 2-3 minutes each, you wont flood your TT if your standing there "managing" what your doing, runs clear for me every time, after that add a little water to the black tank, then release the grey and go home, works for me
