Dump Both Gray Tanks At Same Time

[FlyStar]

Question: Any reason why I can’t save some time and dump my 2 gray tanks at the same time?

No reason I'm aware of.

Let'er rip. Only reason I did them one at a time in the beginning is so I could figure out which tank is 'grey one' on the interior panel. Now they both go at the same time.

I've never done it any other way (except when I want the kitchen tank to fill completely up and sit there to soak the sensors - then I'll just drain the bathroom tank).

I have always dumped mine simultaneously. More flow rinses the crap from the black tank better when you don't have a chance to rinse it with a hose (e.g. at a dump station with others patiently waiting behind you).

Different rationale than prior posters... The galley tank is first because it tends to have significant odor from bacteria from the residual food and grease washed from dishes. The bathroom grey is last since it has none of this and a high concentration of soap from showering.

Interesting. I have never had any foul odor from either of my grey tanks, but I agree, it's something to consider.

Well, not from the black tank, actually, since the grey tank just connects up to the discharge hose, and doesn't flow through the black tank. It does help "clean up" the hose, though.

I was referring to the discharge hose. I guess I should have been more specific when I made the statement about rinsing it.

This how I dump mine too. That kitchen gray tank water can be a bit ripe sometimes.
