Never had one before, trying to work it out. No instructions in the manual.
I hooked a hose from the house (at home) into the 'black tank flush' port.
I turned the water on only for a few seconds and then I was going to open the black tank valve. But water started spraying everywhere so I shut it down!
1) do I need to use a regulator? is there too much pressure?
2) should I had opened the valve first? It seems like people have done it both
ways? I'm getting mixed signals.
3) maybe a plumbing issue but when it's just hooked up for water, everything
is fine. I had an outside shower installed at the dealer where we bought it
and they screwed up and tapped into the black water flush line instead of
cold water line. (Another story). So I took it to a CW as they had to replace
a cracked skylight under warranty. So I had them work on the shower as
long as it was there.
