Dec. 28, Plumbing rough-in. We've got over 1/2 of the under-slab plumbing in place in this photo. Since the house sewer exits about 6 feet above the basement floor, the basement drain plumbing requires a sewage ejector pit (black container near back wall with white bucket on top) and a pump to raise to raise sewage up to the exit level. The piping in the foreground is for (L to R) a bathtub, vent line, toilet, and sink.

Staking and wiring piping in place to maintain the proper pitch of 1/4 inch drop per foot of run (code requirement).
