Would this work for grey/black plumbing?

Our house has a grey water system that empties about 150' from the house. I think there's an outlet from the French drain around there too. Only the toilets go to the septic tank and leach field. So in the spirit of our land, we empty grey water when we get home if we have had no opportunity to empty it before. Unless the ground is frozen, it disappears in less than a minute into the usually parched earth.

One other consideration-- my gray tank came with a 3" outlet, and I attached a 3" gate valve to it. It dumps much faster than the standard 1.5" gray outlet does on other RVs out there.

I have a separate black and gray dump valve, so I must disconnect the line and reconnect once when dumping both. Just a little bit of extra time, not really a big deal. And like I said, with the 3" gate valve, the gray dumps VERY quickly.

I tried to figure a way to use one of those combined units that "Y" together and have separate valves for each tank, with only one sewer connection-- but the way my tanks are configured, and the lack of space, convinced me to just keep them separate.
