I'm planning on running a new sewer line myself. Is 4" schedule 40
sufficient for sewer line when it's buried to a depth of 10-12ft? What
about coupling the pieces of pipe together? Are glued couplers sufficient,
or should the joints have rubber sleeves over them in addition to glued
couplers?

TIA,
