From what I have seen at dump stations the water supply's never have a threaded hose fitting that would work with a trailer. Makes sense because they don't want people to fill their potable water tanks. I have always seen a metal hook like water nozzle.
Thanks in advance
IMPORTANT!!!! DO NOT USE YOUR FRESH WATER HOSE FOR THIS PROCEDURE. Instead buy a cheap 25 foot garden hose that can be stored separately from your freshwater hoses.
The flush connector is for the black water tank only. There is a spray header mounted inside the Black tank.
Drain your Black tank first then connect a hose from a water source to the flush connector and let it run for about 4 to 5 mins. Then drain the tank again. This should be sufficient to clean out the tank of any solid waste. Disconnect your flush hose at the flush connector and run some fresh water through it andthen disconnect it from the supply source. When you store your flush hose,DO NOT STORE IT WITH YOUR FRESH WATER HOSE(S).
Ifyoucan'tuse thetank flush, because you only have the "hook" nozzle then you'll have to wait untilhave the ability to flush it. The "hook" nozzle isused to clean outyou tankdrain hoseafter you've dumped your tanks. The dumping sequence for your tanks is from the dirtiest to the cleanest as follows: 1stBlack water, 2nd Gray water (kitchen), 3rd Gray water(bath).
