I tried to blow air with the air compressor thru the line downstream to the black water tank but still could not get flow. Any suggestions short of removing the tank or nozzle from the tank. Would have to remove the drain valves from both the black and grey tanks to remove the spray nozzle from the tank. Thanks for any suggestions.
my black water flush system anti syphon valve was malfunctioning similar to yours. then it started leaking.
i removed the anti syphon valve and installed a loop of plastic tubing with fittings and clamps in its place. i use an external anti syphon valve on my external flush line hookup. i wait until the black tank is about half empty to pressurize the flush water system to make sure that black water does not come out of the external anti syphon valve.
i learned from this forum to use a capful of calgon liquid water softener from wally world and a capful of sun or other inexpensive liquid detergent as additives most times when i dump to keep the original equipment quantity indicator system working well.
i find that after about a week, my black tank stinks pretty bad.
i learned from this forum that a denture cleaning tablet will control odor in the black and gray tank. i dissolve a tablet or 2 in warm water then dump it in the tank.
i purchase a package of 24 tablets from a dollar store for $1.
btw, i am parked tonight in the wally world parking lot in los banos, ca.
they welcome rv'ers and it a great place to park.
