How to convert sump to a pvc setup - Page 2

I use both PVC (sched 40) and vinyl with stainless hose clamps on the barbs. The old vinyl lines are 21 years with no problems. The PVC manifold's barbs, tees, gate valves and couplings get bulky. I have had to replace all the PVC as it clogs up over the years with calcium and feather worm tubes, so go up one pipe size if you can to avoid flow issues. The vinyl is easy to clean - just squeeze it and the stuff breaks off and heads downstream. I think the lack of elbows on the vinyl is a plus for flow compared to PVC, but the barbs are constrictors. Vinyl is easier to construct and you don't need unions so its probably cheaper too.
