New to Forum - What's this dump handle for?

Hi James, that should be your kitchen grey tank. The one labeled grey tank under the black tank will be your bathroom grey. I have a 2018 328M and that's how mine is set up. Good luck!

This is correct. I have the same rig

I have a 2017 328M. The black handle behind the rear axle is the gray water drain valve for the Kitchen sink & clothes washer (if you are using a washer). Opening this valve will drain the rear gray tank into the same line as the front gray water drain line. You're correct, the two silver handles are for draining the fresh water tanks.

Redkodiak,

Thanks for the reply. Does each tank level show up on the touch screen? Been busy installing and in line canister fuel filter system with swivel joints. What a difference in dealing with the fuel dispenser hose!

My 349 has a rear tab which dumps the sink water.
It also has one by the black water drain and water inlet. This one drains the bathroom grey water.
