Sewer Line Repair in North Walpole, NH
The run from a building in North Walpole out to the public main is the property owner’s responsibility, and in housing of this age it is the one material that cannot be ruled out by a date. There are 251 occupied homes here, and across all the housing the median build year is 1951 — the best single clue to what the pipe is made of and how it tends to fail.
In short
Orangeburg cannot be ruled out by date in North Walpole, where housing typically dates from 1951 and the plumbing code still permitted bituminized fiber. What settles it is whether the pipe still holds a round section.

What a camera survey should settle here
