Should I get a camera inspection before buying an old house?
Yes, scope the lateral before buying any pre-1970 Philadelphia home. The sewer lateral is the most expensive invisible system in the house, sellers almost never warrant it, and one camera visit with kept footage costs a small fraction of a single lateral correction while converting negotiation from suspicion to arithmetic.

Philadelphia rowhouses concentrate the risk. Blocks across Fishtown, Kensington, Point Breeze, South Philadelphia, and West Philadelphia hide vitrified clay laterals with joints approaching a century of shifting, cast iron stacks thinning from the inside, and 1945 to 1972 Orangeburg fiber segments that deform rather than endure. Replacement crosses the front sidewalk or areaway to the city main with permit handling, surface restoration, and depth charges that move the total far more than pipe material, which is why a lateral surprise dwarfs most other inspection findings. A pre-purchase camera with footage marks, material and diameter log, depths at defects and the curb, and a surface locate prices that exposure before you own it: either the line is sound and the purchase proceeds with confidence, or the footage values the correction the offer must reflect.
Schedule the scope inside the inspection window and demand documentation, not a verbal thumbs-up. The operator should launch from an accessible cleanout, run to the main with narration, surface-locate key points with depths, demonstrate flow under load where capacity is questioned, and hand over the video file with a written defect summary you retain. Where the line runs fully blocked, insist on the correct order: cut to full diameter, flush fines where the pipe is sound enough, then scope the cleared line so joints photograph instead of debris. A scope that photographs a wall of sludge and declares failure has frightened without informing, and that distinction has killed sound purchases and blessed failing ones alike.
Use the findings proportionally. Sound pipe with light coating means proceed and budget a routine jetting with verification. A single root joint or isolated offset means proceed with eyes open: price scheduled maintenance or a spot repair, confirm any buried-lateral coverage on your homeowner policy, and plan the cleanout installation older rowhouses so often lack. Orangeburg, collapse, voids, or joints failing along the whole run mean renegotiate, credit, or walk, because those are capital projects with sidewalk restoration attached. Whatever you decide, the footage transfers with the house as an asset the next owner inherits, and it disciplines every future bid, since contractors pricing from the same file compete on judgment rather than imagination.

Follow-up questions
Who pays for the pre-purchase scope?
Custom varies by deal, but buyers usually order and pay since they keep the footage either way. Some sellers credit or split it once footage documents a defect both sides accept.
Will the seller accept a price reduction for lateral defects?
Documented footage with depths and a written scope converts the ask from opinion to line items. Whether they concede depends on the market, but footage negotiates while adjectives do not.
Services behind this answer
Sewer Camera Inspection
Every expensive sewer decision in Philadelphia — jet, repair, line, replace — depends on one thing: what the pipe actually looks like inside.
Main Sewer Line Cleaning
The lateral is the most expensive drain you own — a 60-to-100-foot clay run from your rowhouse to the street main, shared with stormwater, hunted by street-tree roots.
