Plumbing re-do project is complete and after replacing every bit of PVC above grade - I found a leak once I turned the pump on - on the spa side return at the union from the 90 on the the jandy to the below grade line. (I'll take a pic today). Other then cutting it up is there a good fix for this? I was thinking of lathering up the joint with pvc cement and putting a shop vac on the line to draw the glue in.
