We have a 2015 Sierra FLIK fifth wheel RV. My question is: Is the galley & gray tanks plumbed together? I have dumped my galley tank two days in a row. Gray tank doesn't have third of a tank in it. Under the specs for our fifth wheel it list a fresh, gray & black water tanks. Does not mention a galley tank! Any information would be appreciated!
Grey and galley tanks are not connected on any trailers I know of. I hard plumbed them together on mine so I wouldn't have to crawl under the slide out to empty the galley tank and hook and unhook hoses or use 2 separate hoses and a wye. 4 hrs and about $25 and the problem is eliminated permanently.
I have a 2015 366fl, that only has a Grey and Black Pull Valves. Spec say both tanks are 54 gal each, I have a Kitchen and bathroom with shower and sink. So they must all go into one tank? Yet my tank lights show Grey and Galley tanks along with my Black.
