Sewer Camera Inspection & Line Locating
Sewer camera inspection is a diagnostic process where a waterproof camera head is pushed through a lateral to visually document pipe material, joints, defects, and blockages, while a sonde transmitter on the camera head lets us locate the pipe's exact path and depth from the surface.
When you need it — and when you don't.
When you need this
- Recurring drain backups where snaking clears the symptom but you need to know the actual cause before spending money on repairs.
- Buying or selling a home, especially one built before the 1970s, where the township or a buyer's inspector wants documented proof of the lateral's condition.
- Before any excavation, landscaping, or hardscape project (patio, driveway, addition) that will cross or sit near the known or suspected sewer line path.
- Slow drainage, gurgling fixtures, or sewage odor in the yard that hasn't been diagnosed, where you need to see what's actually happening inside the pipe.
- After a lateral repair or replacement, to confirm the new pipe holds proper grade and the joints are sound before backfilling is finalized.
When this is the wrong fix
- If a fixture backup is isolated to one drain (a single sink or tub) rather than the main line, the issue is almost always in that branch line, not the lateral, and doesn't need a full mainline camera run.
- If the line has an active heavy blockage, a camera run often can't get past it — jetting or snaking to clear the obstruction usually needs to happen first, then the camera goes in to see what's beneath it.
- If you already have a recent, complete camera inspection on file for that exact line and nothing has changed since, paying for a repeat inspection is unnecessary.
How it's done.
The inspection starts at an existing cleanout or, if none exists, through a pulled toilet or a temporary access point. The camera head, mounted on a flexible push-rod, is fed through the line while a technician watches a live monitor and records footage, noting pipe material, joint condition, any cracks, offsets, bellies, root intrusion, or scale buildup, and the location of any lateral connections. A sonde (a small radio transmitter built into or clipped near the camera head) emits a signal that a handheld locating wand picks up from the surface, allowing us to trace the exact path of the pipe and mark it with paint or flags, along with a depth reading at each marked point. This combination — visual footage plus surface locating — is what lets us tell you not just that there's a problem, but exactly where it is and how deep, which is essential information before excavation, before trenchless repair planning, or before any other utility work crosses that path. Footage is reviewed with the homeowner and, where useful, provided as documentation for permitting, insurance, or a real estate transaction.
Materials & standards
| Item | Typical practice |
|---|---|
| Camera head | Waterproof, self-leveling color camera on a push-rod reel |
| Locating method | Sonde transmitter paired with a handheld surface locating wand |
| Typical access points | Existing cleanout, roof vent, or a pulled fixture where no cleanout exists |
| Documentation | Recorded video footage plus a marked-up depth/location sketch |
| Surface marking | Paint and flags at each located point along the pipe run |
| Common pipe materials identified | Clay, Orangeburg (bituminous fiber), cast iron, PVC |
How the job runs.
- 01
Locate or establish an access point — an existing cleanout is ideal; otherwise a fixture is pulled or a temporary access is cut.
- 02
Feed the camera head through the line at a controlled pace, recording continuous footage of the pipe interior.
- 03
Note pipe material, joint spacing and condition, and flag any defects (cracks, offsets, bellies, root intrusion) with a footage counter reading.
- 04
Activate the sonde and walk the surface with the locating wand to trace the pipe path and mark it at grade.
- 05
Take depth readings at each marked point along the run, including at any defect location.
- 06
Review the footage and marked path with the homeowner and explain findings in plain terms.
- 07
Provide a written summary or footage copy for permitting, insurance, or real estate documentation as needed.
What moves the number.
Every site is priced individually after we have walked it, in writing, with the scope itemized. These are the variables that decide where a job lands.
| Factor | Effect on price |
|---|---|
| Line length and number of access points | A longer lateral or one that needs a fixture pulled for access takes more time than a short run with an existing cleanout. |
| Presence of an active blockage | If the line has to be jetted or snaked clear before the camera can pass, that's additional work beyond a straightforward inspection. |
| Number of locating points needed | A full-length surface trace with marks every few feet takes longer than locating a single defect point. |
| Documentation requirements | Formal written reports or footage packages for real estate or municipal purposes take extra time to prepare beyond the on-site inspection. |
Questions we get, answered.
It's the single best tool for that decision. The footage shows whether you're dealing with one isolated defect or widespread deterioration, and the pipe material and joint spacing tell us a lot about remaining service life, which together point toward a spot repair, lining, or full replacement.
It helps but isn't required. If your home has no cleanout, we can usually access the line through a roof vent or by pulling a toilet, though an existing cleanout makes the process faster and is something we'd typically recommend installing during any future repair work.
Sonde locating gives a reliable depth reading directly above the transmitter, accurate enough to plan excavation or trenchless work with confidence. Depth can vary along a run where the pipe's grade changes, which is why we take readings at multiple points rather than just one.
No. The camera head and push-rod are designed to travel through pipe without contacting it aggressively. If the line has sharp offsets or a partial collapse, the camera may simply not be able to pass that point, which itself is useful diagnostic information.
Yes, footage and a written summary can be provided, which is especially useful for real estate transactions, township documentation, or your own records before and after repair work.
