9Repair & lining

Five methods cover nearly every house sewer job. EPA calls one of them the most proven, and a camera recording usually decides which of the others is even possible.

A liner hardened inside the old pipe can replace digging, if the host pipe still holds its shape. Two ASTM standards govern it, and the 50-year figure is a design target.

A liner takes the shape of the pipe it goes into. That single fact rules out collapsed runs, reverse slopes and brittle old fiber pipe, and it is why the camera video comes first.

The state plumbing code allows bursting an old house sewer only within set sizes, with one pipe type and two recorded camera surveys. What that means for an older Westchester lateral.

One broken section, or a whole line of tired joints? How EPA frames the choice, what a camera has to show first, and where town lateral standards come in.

Cured-in-place lining uses resin that can give off styrene. Purdue researchers traced how fumes reach living space through plumbing, and what to ask a lining contractor first.

There is no official price list for a lateral. The bill is built from a handful of factors a homeowner can check on the camera video and the site before asking for quotes.

State rule 16 NYCRR Part 753 puts the notice duty on the excavator, sets a 2-to-10 working day window and a tolerance zone, and leaves the private sewer lateral unmarked.
