"My water heater started leaking on a Sunday. I reached out to Family Fire Service and they responded immediately. They had a new water heater out to my house the next day and installed in a few hours. The supervisor and the tech worked seamlessly to have us up and running. They provided quality service and at a very competitive price. I highly recommend Family Fire Service and Plumbing. KC"

During the inspection, you’ll watch a high-definition video feed that shows exactly what’s going on inside the pipe—everything from minor buildup to major cracks. Your plumber pauses the footage to explain what you’re seeing and why it matters. Bright lights and self-leveling cameras make sure each section is captured clearly, so you leave with a complete picture of your sewer’s health.
Most professionals complete a standard sewer camera inspection in an hour. That window covers setting up the gear, guiding the camera through the line, and reviewing the footage with you. If your house lacks a cleanout and the technician needs to pull a toilet or access a vent stack, tack on a little extra time—and cost—for that added work.
Yes, a sewer camera inspection can help you identify septic system problems. A sewer camera gives your pro a live view of the pipes leading to the septic tank, so they can spot blockages, corrosion, leaks, or other red flags without guesswork. Pinpointing the problem quickly means you can plan the right repair and keep the entire septic system running smoothly.
