No valves. Just screw the hose on and turn on the water.
Not to sound stupid, but are you sure water was coming out the hose?
Mine almost instantly has water coming out the dump valve
Thanks for the response. That's what I thought it was supposed to do as well. I read somewhere on here where someone had a new RV and the black tank flush check valve was installed backwards. I'm wondering if that's what is wrong with mine.
Yeah there was water coming out of the hose. That was the first thing I checked. I could also tell there was water because the garden hose from the dump station didn't seal perfectly and was spraying a jet of water from the connection. Not enough to cause a drop in pressure but enough for the jet to land about 6ft away.
I'm going to call the dealer in the morning and see what they say about it.
