Noticed that PVC line between grey tank and drain valve has hair line crack in it. Is the a way to fix it without having to replace the pipe? Maybe with JD Weld for PVC & Plastic?? Thank you
Drill 1/16 inch holes just beyond each end of the crack and repair as described above. The holes prevent the crack from propagating. I have had success with Water Weld. You may have to open up the crack to stuff in the epoxy.
