Sewer Line Repair in Smithtown, NY
The run from a building in Smithtown 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 11,834 occupied homes here, and across all the housing the median build year is 1967 — the best single clue to what the pipe is made of and how it tends to fail.
In short
Bituminized fiber pipe — Orangeburg — went into the ground alongside clay across the years Smithtown housing typically dates from, which is 1967. It deforms into an oval rather than cracking, so the pipe becomes the restriction and clearing it restores nothing.

What went in the ground around 1967
A lateral laid in Smithtown in that period is most likely Orangeburg or cast iron, with clay still going in at some depths. Which of the three you have is not something the build year can settle on its own. More on Orangeburg pipe.
What a camera survey should settle here
Three materials were going in the ground at once in these years, so the survey is identifying the pipe before it diagnoses anything. The full picture on Orangeburg pipe.
Smithtown is the 59th largest block of laterals we cover in New York, carrying about 0.2% of the 4,931,173 homes on our NY list, and its housing runs older than 39% of the NY towns we route. Age concentration matters on a lateral: where a whole street went in one season, the failures arrive in one season too.
86% of homes here are owner-occupied — 40 points above the NY figure. That matters more on a lateral than on almost any other pipe in the house: the run from the building to the main is the property owner’s to repair, and a landlord and a resident owner do not find that out at the same speed.
Median household income across Smithtown ZIP codes is $141,505 — the number to read against a repair that is the owner’s alone.

Before anyone digs in Smithtown, get the run on camera — and ask what the pipe is actually made of, because the build year cannot settle it at this age. What the recording should show you.
