Hi FishyFishy

This is the original way I have it, all my bulkheads are slip fitting, the main line in the photo with strainer is with a gate valve, the center is not restricted right to the sump, the far pipe with strainer is the secondary has a ball valve.

I am ordering a T for the durso, that will slip in where the secondary is.

I designed this to be flexable.
