PVC Drainage for Grey and Black water

Hi I'm a newbie!! Just bought a 2011 flagstaff HW 25 SC popup camper. Love it!! Question is: Black and grey emptying of tanks is awkward. There is usually only one sewer drain in most camping locations, so how can we configure a "y" connection for both tanks to drain into sewer pipe at campgrounds? At present, we are having to hold sewer slinky at both grey and black values to empty them. . . yuke! Would like to hook up at campsite and not worry about emptying every few days. Has anyone ever made something like this or is there a better method I'm not aware of? Thxs a bunch!

Valterra - Rotating "Y" Sewer Connection - Sewer Fittings - Camping World

There are other types out there as well. This is the type I use for my bath & a half with 2 terminations to the campground sewer connection.

Thanks for the link! Another question, how to I connect grey water hose to this? Our grey water is a garden hose opening, so how does it it to this "y"?

Not sure about yours, but most all campers have one place to hook the sewer hose, and then two handles to pull, one for gray water, and one for black water. Does your camper have two holding tanks along with a fresh water tank? I can't find anything on tank size on Forrest River web site. Are you sure someone didn't put an adapter on like in post #4?

Before this gets out of hand, there are some campers, with two gray tanks, but they are usually over 25 feet, with a bath near one end, and a kitchen near the other.

Since your total length is only 12 foot, not much room for that.

You say you are new I hope you realize that you need to keep the valves closed till the contents build up then drain them every few days or when they are showing more than three quarters full draining the black water first.

Can you post a picture of your setup?

Pictures can be helpful for others to see what you have. Using a smartphone camera can come in handy.
Great choice for "Living within my means" and camping for one...
