I've been reading the forum since we picked up our new Primetime 297RSK 5er.
We're getting getting ready to take our first trip and I'm checking all systems to assure we are ready. Every seems ok so far. The last couple of days I sanitized the fresh water system and wanted check the waste tanks. I wanted to assure they didn't leak and that the valving works correctly. (Better to check with fresh water that I can dump on the ground than waste that I can't discharge freely.)
I had thought that the 297RSK has 1 Black tank and 1 Grey tank. Today while testing the tanks discharge I found a second valve with a grey handle???
When I add water to the grey tank from the kitchen or bathroom only 1 tank gauge shows a level increase
There is a grey handle and a black handle valve in the basement area. I found a second grey handle valve by the sewer hose connection.
I'm hoping someone can lay out what the second grey valve is for.
Thanks for the help
