2 Drain Valves....

[mikdor1]

We have a 2017 FR 524rlws 5th wheel. Was reading on a forum today that someone had a problem with black water coming out of their kitchen sink drain. Someone else replied that it was normal to have kitchen sink drain into black water tank. If I have 2 drain valves does that mean i have the same scenario ? Just curious but I think that would be ok because we would always dump our dirty kitchen sink water into toilet of our old camper to help fill it up more so we would have more pressure in tank when we dumped. I don't think we would have an issue because we typically only camp 3 nights.

Not necessarily, no. You have two valves because of two tanks: a black tank for toilet and a gray tank for everything else (although as you've read that isn't an absolute). The black handle dumps your black tank and gray for the gray. It's most likely yours is plumbed normally.
