DC70,
Thanks for providing additional real life experience with your system! Could you please clarify what you did when you said “So I cut the pipe off 12 inches below ground level and capped it while running a 4 inch pipe over 3 feet with an elbow then up to the surface with a vent cap flush with the ground.” I understand that you cut the 18” pit 12” below ground and capped it, but I’m not clear on the 4” inch pipe over 3 feet with an elbow. Where is the 4” inch pipe over 3 feet connected? Is it on the vent supply pipe (sock pipe), 18” pit or vent pipe?
Thanks,
Heppy
