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
