Underground PVC Drain Pipe – Glue???
Hello! I recently had an underground drain line replaced with 4” PVC around an egress well. This drain line services a sump pump discharge, as well as a gutter drain. The PVC connections were NOT glued before they were covered with 18” of gravel and another 6-8” of top soil. Do these connections need to be glued, or will the surrounding pressure from gravel and dirt keep them from disconnecting? Picture attached for reference.
Thanks for the input!
