How Does 72 Degrees Texas Diagnose Sewer Line Issues?

Question

Accepted Answer

With a camera, and with a locator. Video shows what is wrong; the locator tells us exactly where it is and how deep. Both matter, because in Hill Country soil an imprecise repair is an expensive one.

Starting With the Symptoms

Before equipment comes out, we want to know what the system is doing.

Multiple fixtures backing up at once points to the main lateral rather than a branch. A toilet gurgling when the washing machine drains indicates a venting or main line issue. Water rising in a tub when a toilet flushes means the blockage is downstream of both.

Slow drainage across the house differs from one stubborn fixture. Sewage odour indoors, wet spots in the yard, or unusually green patches of grass along the sewer run all point somewhere specific.

You live with the system, so what you have observed narrows the field before we start.

The Camera Inspection

A flexible camera is fed through the line from a cleanout, transmitting video as it travels.

It distinguishes problems that are identical from the fixture: soft blockage, grease or scale coating the pipe wall, root intrusion at a joint, a bellied section holding standing water, an offset joint, a crack, or a collapsed section.

Those are seven different problems with different repairs. Guessing between them is how homeowners pay for the wrong work.

You watch the screen with us and you get the recording. That is deliberate — it is the honest protection against being sold a sewer replacement you did not need.

Locating and Depth

Our cameras carry a transmitting sonde. Above ground, a locator picks up that signal and marks the exact position and depth of whatever the camera found.

This is the step that controls cost. Knowing a root intrusion sits eighteen feet from the cleanout at four feet deep means a targeted excavation. Not knowing means exploratory digging along a sixty-foot run.

In Hill Country soil, where excavation hits limestone and costs climb accordingly, that precision is worth a great deal.

Reading What the Camera Shows

Interpretation matters as much as the footage.

Standing water in a section means a belly — the pipe has sagged and lost its grade. This causes chronic recurring clogs, and no amount of cleaning fixes it because the problem is grade rather than blockage. Homeowners who keep paying for cleanings on a bellied line are on a treadmill.

Roots at a joint indicate a separated or cracked joint admitting them. Clearing the roots without addressing the entry point means they return.

Scale and corrosion in cast iron — common in older Fredericksburg and Kerrville properties — narrows the pipe progressively and creates rough surfaces that catch debris.

Since 1986 we have looked at enough Hill Country laterals to know what is normal for the local building stock and what is not.

Other Diagnostics

Where the camera cannot reach — a fully blocked line — we clear enough to get the camera through, then inspect.

Smoke testing identifies breaks and improper connections in a system. Dye testing traces where a specific fixture actually drains, which is useful in older properties with undocumented plumbing.

Where a leak rather than a blockage is suspected, leak detection equipment locates it without opening ground.

What the Diagnosis Leads To

The recommendation follows the evidence. Soft blockage means drain cleaning. Grease or scale coating means hydrojetting. Root intrusion at a joint means a repair rather than a cleaning schedule.

A belly means excavating and re-grading that section. Structural failure means main sewer line repair or replacement.

Sometimes it means monitoring — a minor issue worth watching rather than repairing today. We say that when it is true.
