NORTHGATE | Sewer liner replacement at residential homes

A few weeks back, we started working on a drain repair in Phoenix after a resident in the area mentioned their sewer draining issues! 

After a camera inspection, video evidence showed issues with the sewer that 6 homes feed into. The mainline was holding water in the same exact spot.The clay pipes had developed a 12-inch “belly”, causing all the gunk to get stuck in one area of the pipe. 

We excavated the pipes in one go because they’re all on one main sewer. We dug approx. 5 feet deep and completed a 45-foot-long sewer replacement.

Why Did This Happen?

A normally functioning sewer lateral typically has a slope that uses the force of gravity to facilitate flow. The pressure from your flush should generally be enough pressure to move the wastewater through the pipes. Erosion, angling of the pipes, and quality work are various reasons for a belly (a sag or downward bent section of the pipe) to occur.

The biggest reason for bellies in sewer systems is the lack of proper soil bedding during installation. And yet even if this is all done perfectly, other factors like tree roots, earthquakes, sun, heat, rain, and extreme temperature fluctuations can also result in shifting soil, which then can cause bellies.

How Can You Diagnose a Sewer Line Belly?

To identify a sewer pipe belly, advanced video inspection technology is necessary. During a sewer camera inspection, a video camera is fed into the pipe, providing a clear look at the sewer lateral. This helps the plumber to pinpoint any issues present. Sewer line camera inspections can also uncover incorrect slope issues.
