If you wanted to pull off the two in one pipe idea your going to have to use something like a 2.5in pipe. You could run a 1/2 to 3/4 in return line through the core of the pipe and up through the center of a stockman. You cant do it the opposite because there is no easy way of getting the drain from the core of the pipe through the sidewall of your pumping pipe. Just remember you have to use a large pipe because filling the core of your pipe is going to make your drain terribly ineffecient.
