Sewer line Inspection / Private Sewer Lateral

Sewer lines are a vital part of our homes and businesses.  Every time we use a sink, take a shower, or flush the toilet, our sewer lines are performing a delicate balancing act in order to continue flowing. As property owners, we just assume that whatever goes down the drain is gone, as long as it doesn’t come back up into the drain that is. But there is much more to the story. Your sewer might be on the brink of failure, or even already failing without you even suspecting it until a dreaded backup occurs.

Some of the biggest costs property owners face may be plumbing and sewer line repair or replacement. The damage that can come with flooding from broken or backed-up sewer lines can also be costly. The good news is that you can have peace-of-mind by getting a sewer line inspection done by US Trenchless of Sacramento and San Jose.

When you select US Trenchless for your sewer line inspection needs, you can be sure that you are getting the very best. Our highly trained service technicians use state-of-the-art cameras and recording equipment to provide a real-time visual assessment that accurately identifies the condition of the sewer line and pinpoints any problem areas. If problems exist, we will provide a professional estimate of the cost for repairs, giving you the most accurate information possible, and allowing you to make informed decisions. If you do need further work done, US Trenchless can handle that, too, without disrupting your life or your landscaping. We specialize in pipe bursting and cured-in-place-pipe (CIPP).


Per section 718.1 of the Uniform Plumbing Code (UPC), sewer lines are required to be installed with a minimum grade (or slope) of not less than ¼ inch per foot. That doesn’t sound like much, because it really isn’t. The idea behind this requirement is that water breaks on a plane with a minimal grade. It’s best if the water doesn’t flow too fast, otherwise it will “run” away from the solids. What this means is that your sewer line is barely draining when it’s brand new and working perfectly. Imagine what years of soil settling, pipe deterioration, and root intrusion can do. There may be inflow and infiltration (I and I), allowing groundwater and storm water to enter your pipes and tilt the delicate balance in your pipes even further out of whack. What’s frustrating is that you can’t see the effects of these problems until it’s too late. Let US Trenchless help.

History of Sewer Line Inspection

In the early 1980’s a camera was invented that could go into the sewer pipe. Finally, it was possible to see what the problems were and just how bad they were, in real time. Today, the technology has improved and become readily available, however most people still aren’t taking advantage of the opportunity to identify and solve their sewer and pipeline problems. Most sewer line inspections are done as part of an emergency repair job. By this time, the sewer has stopped working entirely, creating problems that go far beyond what it would have taken to fix the problem earlier. All of this hassle and mess can be avoided, and thousands of dollars can be saved, with a camera inspection of your pipeline by US Trenchless of Sacramento and San Jose.

Some agencies have become concerned about this problem, and enacted laws to save new property owners a lot of agony and unnecessary expense.  In the City of Alameda, CA Ordinance No. 2404 states: “Prior to sale, properties over 25 years old must have their sewer lateral tested for infiltration. If a property is tested and passes, it is certified for 5 years and need not be re-tested if resold during that period. If it fails, the lateral must either be repaired or replaced and then re-tested. Replaced laterals are certified for 25 years, and those that have been repaired are certified for 5 years. The owner is responsible for having the mandatory test performed, obtaining the permit and providing the certification.” Many other municipalities in California such as Berkley, Santa Barbara, and Ukiah have adopted this standard and more are in the process of doing so.

Finally, leading realtors have recognized that a sewer inspection is equally as important as the usual roof and termite inspections. Don’t get led blindly down the path toward unexpected problems. Get a sewer line inspection and put you mind and wallet at ease.

No Fuss, No Muss Process

When US Trenchless comes out to perform a video inspection of a pipeline, the process is simple, non-destructive, and highly effective in finding any areas of concern. First, our certified technician places the camera into the pipeline. Then, as the camera is pushed through the piping, it records its voyage. The images recorded by the camera are immediately visible to the service technician, who processes the findings and provides a comprehensive diagnosis. The process takes very little time; the property remains clean and free of damage, without any inconvenience to the seller. Help your clients make the best investment decisions by arming them with information about the location and condition of the pipelines for each property they are considering buying. At your request, inspection footage can be archived for future reference.
