2013 ultra lite 310LTD. HOLDING TANKS

[Fastfields]

Picked up new camper last week. Still trying to figure out the tanks. Has gauges for 3 grey water tanks and 1 black. The real problem is figuring out which handles dump what. Anybody have this model? Oh yea my bedroom sliding door fell off before I could get he with it. I reinstalled roller in a different spot and it was off again before I got 10 miles. It had already been fixed one time before by looking at the holes in the door. I see that others have had this problem

Welcome to the forum!

Grey tanks normally use small outlet pipes . Black uses larger diameter pipe.
Dealer should have showed you this during pdi.
To figure which is which make sure are empty.
Then put five gallon of water in kitchen sink then pull handles till you find what tank has 5 gallon in it.
Repeat for all tanks .
My unit is not same make and model but.
Front gray is bathroom sink and shower.
Black is next toilet only
Second gray is kitchen sink only
3Rd gray is outside kitchen sink.

My levers are labeled as well.

Yea I don't like how the plumbed the tanks. The large valve has to be opened to dump 1 or 2 of the grey water tanks. I think the black water is a handle that is attached to a cable that may go to other side of trailer. Not sure. I'll have to run some more test.
