I attempted to use the black tank flush system today but encountered an issue. I hooked up my hose to the connector, open the dump valves (drained tanks prior) and left them open, then turned on the water to flush the tanks. Well water spurted out from the connection. I thought maybe it was the pressure but I tried running it with the water barely on and with the regulator... same results. Water was coming out the sewer hose but very little. All connections were tight was well. I used a 15ft garden hose from Lowes. Does it have to be a RV/Marine hose?
