I’m finally trying to finish my plumbing and the return pump is not ideal.
This is the setup currently
I will remove the union right at the sump as there isn’t quite enough clearance for it, so I’ll just have the upper union. The problem is that I have to be very, very precise on the length of the horizontal piece on the right. What’s the best way to get the length correct? I’ve found that once I glue the pipes together, they fit into the joints deeper than when dry fit. With the spacing of the drains, there isn’t really room to move the sump more than a millimeter or two. I’m sure there’s some trick professionals use - can anyone help?
