New to me trailer question

Our 2007 Surveyor has 2 holding tank outlets(side x side)but about 8 inches offset. we use the red "Y" pictured above at all full hook up sites. Just use one hose at dump stations and empty black tank then gray, then rinse out hose if flush out hose is available.

We have the same setup, two outlets (on either side of the axles) with three valves. I have never had a problem only using one outlet at a time. The kitchen grey tank(front outlet) does not fill nearly as fast as the bath grey (rear outlet). So I just leave the hose connected to the rear and dump those tanks when needed and move the hose to the front and dump that one. This eliminates the need for extra connectors and hose ramps.

Keep it simple and be happy.

Yes you can bring 2 hoses to the Y and then in the sewer. When we were seasonal we used PVC pipe instead od the hose and it worked gret, something to think about. Good luck.

Yes there are three valves to two outlets. Thanks these look good, I've never seen two separate outlets.

I bet you have 3 dump valves.....2 in the rear (1 for black and 1 for grey) that go to same dump line and then the one up front for galley.

Anyways........

Hard pipe it using the 'Y' like path1 posted
