Sewer & Drain Line Inspections

Legacy Plumbing offers advanced sewer and drain line inspections with pipe cameras and hydrostatic pressure testing in Frisco, Plano, North Dallas and surrounding cities.

If you’ve been told you have a sewer line leak  or frequent drain clogs and backups you probably need to have your drain system professionally investigated. Legacy Plumbing specializes in advanced sewer diagnostics. Every truck carries a sewer inspection camera and all the tools necessary to properly assess sewer and drain pipes.

Whether you have a section of deteriorated pipe, a broken fitting, a belly in the line, or a full break… our licensed plumbers have the experience  to diagnose and fix residential plumbing systems and plumbing issues.

Sewer Line Video Inspection and Locating

Sewer inspection technology has come a long way. Our sewer cameras can go up to 100 feet into the drain system and return a clear, real-time video to the monitor. Furthermore, these cameras come with locating sondes. This means that once we visually identify the sewer line problems we can pinpoint the exact location above ground with our locating wand. 

What Cameras Can Do

There are many things you can visually diagnose with a sewer inspection camera. You can often identify breaks or offsets in the sewer line, root intrusions, foreign objects, and bellies. A belly is a section of the pipe that does not have proper slope (or backfall) and always retains water in the pipe even when there is no stoppage. Being aware of the presence of bellies can give you a heads up for future backups down the road and protect your North Texas home from potential sewer line problems.

What Cameras Cannot Do

One limitation of the camera is that it can only see when the pipe is clear of obstructions. If the line is full of cloudy or muddy water, then visibility is limited. Legacy Plumbing typically needs to unclog the system first before we can positively identify the cause of the backup. If we are unable to clear the clog because the pipe is badly damaged, then we can run the camera down the sewer line until it reaches the clog and will not go any further. We can locate that spot as a starting place.

Hydrostatic and Isolation Testing​

Some other methods Legacy Plumbing uses to test sewer lines are the hydrostatic test and isolation testing. These unobtrusive procedures allow us to determine unquestionably whether there a leak on the sub-slab sewer piping and pinpoint where that leak is.

Static Testing

This test consists of purposefully capping off the main sewer line where it exits the foundation. Once the only path of escape is blocked, we can fill up the sewer system with water until the water line reaches the level of the slab foundation.

You can watch the water level for a period of 10 minutes. If the water line starts to drop, it indicates that there is a leak somewhere in the system.

Isolation Testing

Isolation testing uses the same principles as static testing to locate leaks in sewer lines. Using the inspection camera, you can move the test balloons to different parts of the system to block off sections and test them individually. In this way, you can narrow down the precise pipe fitting that is leaking even if the issue is not able to be discovered by visual inspection only.

Using these tools along with a refined diagnostic methodology, Legacy Plumbing technicians are able to quickly and efficiently pinpoint sewer line problems under the slab and under the yard before they are excavated. This saves North Texas homeowners time, money, and keeps the disruption of your house and yard from plumbing issues to a minimum.
