A camera inspection puts a view inside the pipe so the condition of the line can be assessed directly instead of guessed at from the symptoms above ground.
A push camera travels the drain and returns live footage of the pipe wall. That reveals root intrusion at joints, grease and scale build-up, cracks and fractures, offset or separated joints, bellied sections holding water, and foreign objects lodged in the line.
Why it matters before digging
Locating the fault along the run means any excavation can be targeted rather than exploratory. It also helps determine whether cleaning, a spot repair, lining or replacement is the sensible next step for the pipe's actual condition.
Good reasons to inspect
Recurring blockages in the same line, a sewer backup, buying an older Niagara Falls property, mature trees near the sewer run, or planning work that depends on the state of the underground drainage are all reasonable situations to inspect first.
