When to dump?

Originally posted by Tim We are going to a campground with full hookups for the first time. Should I wait and dump the black tank when it is 2/3 full? I thought you said not to hook it in to the drain? How about the gray tank? Thanks!

Hello Tim,

Black tank: Do not connect. Wait on dumping until just before you leave. If necessary, add water to get sufficient amount to help remove all contents (2/3 full or more).

Gray tank: Connect and open valve. That way, you can wash dishes, shower, etc. without worrying about the level in your gray tank. A little before you get ready to leave, close the gray water valve so you can accumulate a little water (to be used to flush out your drain hose after draining the black water tank).

Switch the drain hose to the sewage (black water) connection. Open valve. If possible, use the black water tank flush fitting (with a different hose than the one you use for your fresh water hookup) to flush out the tank. You may be surprised at how much more stuff comes out than when you just drain it). Close the black water tank valve and switch the hose back to the gray water tank drain. Open the valve and use the gray water to flush out your hose. close the valve, make sure the covers are in place, stash your hose, and you should be all set.

Thanks!! Great advice.
