Dear Readers, I need to replace my main line of cast iron drain, where the house trap and vent are. I have a septic system. Just before I was going to purchase the PVC pipe, I talked with my neighbor (who has a pump-up septic system). His house has no house trap and no vent. Is this because he as a pump-up system? or is there some exception to the plumbing code that I'm not aware of?
All advice appreciated.
