When we use city water port everything works fine.
Second trip out I hooked hose to city port and then switched valve with X from normal to fill and after 45 mins tank gage showed zero.
I opened drain port at rear of camper (bottom) with ball valve and less than a quart came out…
I went to back of panel and traced lines to a diagram I found on this forum and my piping appears to be correct.
I will cut line to tank to check that the fill valve works.
If it’s not the valve ...
it’s likely a pinched line after the fill valve. [/I][/B]
To trace the fill line to tank will require that the belly skin be removed and it won’t be easy due to the way it is fastened (half tek screws and half fasteners shot shrough with cartridge)
Thanks for the replies.
