3 Key Questions to Choose the Right Sewer Camera
Not every sewer inspection camera fits every job. Answer three questions—drain diameter, line length, and drain type—to match the right camera head, push rod, and features for faster, clearer inspections.
Why These 3 Questions Matter
The right pipe inspection camera depends on the job. Your answers drive the specs: camera head size, push-rod flexibility, reel length, lighting, and whether you need a 512 Hz locator.
1) What is the diameter of the drain?
- 1–2": use a 17–23 mm mini camera head + flexible rod for tight bends.
- 3–4": a 23–28 mm head balances clarity and agility.
- 4"+ mains: go 28–40 mm self-leveling for a wider, more stable view.
Diameter decides head size and rod stiffness.
2) How long is the drain line?
- Home (20–100 ft): a 100–130 ft reel usually covers it.
- Commercial / Industrial (150–300 ft): choose longer reels and a distance counter.
Length decides reel size and whether you need length tracking.
3) What type of drain is it?
- Sewer / main line: robust IP68 camera + 512 Hz sonde.
- Sink / shower / HVAC / pool: mini head + flexible rod.
- Storm / septic: brighter LEDs, abrasion-resistant jacket, anti-corrosion housing.
Drain type decides system grade and must-have features.
Putting It All Together
| Question | Determines | Typical Options |
|---|---|---|
| Drain diameter | Camera head & rod | 17mm / 23mm / 28–40mm |
| Drain length | Reel length & counter | 100ft / 150ft / 200ft+ |
| Drain type | Waterproofing, lighting, locator | Home / Pro / Industrial |
Tip: If you regularly locate underground lines, choose a camera with a built-in 512 Hz sonde and pair it with a compatible receiver.

FAQs
What camera head size should I use for 1–2" PVC?
Use a 17–23 mm mini head with a flexible push rod so you can navigate traps and tight elbows without forcing the cable.
Do I need a distance counter?
If your runs exceed ~100 ft or you provide reports, a counter saves time and improves documentation—especially when marking defects or pricing repairs.
When is a 512 Hz locator essential?
Anytime you need to pinpoint the camera underground—for example to locate a collapse, clean-out, or where to excavate. Choose cameras with an integrated 512 Hz sonde.
