Back fill of sewage pipes
Posted by Bob in MD on March 09, 2004 at 15:56:13:
I am replacing some old iron pipe between my house and septic and then out to the dry well. The pipe is dug out and schedule #40 has been purchased to go in. My question is about the back fill. Should I fill around the new pipe with sand or screened aggregates or just back fill with dirt? I had a blocked line between the septic and dry well and want to do both pipes before I install a deck over the line between the house and septic.
Thanks for your help,
