Sewer Line Replacement & Repair

Even though many minor stoppages are able to be corrected by clearing the lines with sewer cleaning equipment, the problem is not always that easy to solve. Tree roots, bellies in the line, old cast iron or clay tile pipes, ground shifting, and improper installations are the typical suspects when it comes to sewer line damage.

In order to find out what’s causing the problem, we use a sewer video inspection camera to find out exactly what and where the problem is. Our plumbers are experienced in diagnosing sewer problems and finding solutions tailored to your home’s specific needs. Read more about our sewer camera and diagnosis on our Sewer Camera Inspection service page.

Sewer Line Problems

Tree Roots

Contrary to popular opinion, tree roots rarely cause a sewer line to break unless the tree is very large and situated very close to the plumbing line. Most of the time, the pipe breaks first due to ground movement and deterioration, and the roots grow into the pipe because they are attracted to the water that leaks out of the pipe.

PVC Pipe

PVC pipe doesn’t suffer from many of the issues that cast iron pipe does. It doesn’t rust or deteriorate, and the pipe itself does have quite a bit of flexibility. However, the joints or fittings that connect sections of PVC pipe are not as strong as cast iron. When installed properly on stable soil, this is not a problem. However, when the soil isn’t compacted properly during installation or when the ground in that area is relatively unstable, it frequently results in cracked PVC fittings.

Cast Iron Pipe

Cast iron pipe is very brittle by nature, but at every joint there is some flexibility. While movement of the soil does cause many issues with cast iron, many times it is simply the years of rust and deterioration which cause the bottom to fall out (quite literally). The flexibility of the joints also makes it easy for the pipe to settle if it hasn’t been installed on properly compacted soil. If this settling doesn’t crack the pipes, then it often creates “bellies” or sagging places where all of the water doesn’t drain smoothly out of the pipe. These promote clogs and accelerate the deterioration even further.

Ground Movement​

Many places in North Texas are plagued with unstable soil. People who live here are well aware of the foundation issues which affect much of the area. If the force of ground movement can raise or lower a massive concrete slab, think about what it can do to plastic or iron pipe.

Once the PVC or Cast Iron pipe is cracked, it may be quite some time before you ever know there is a problem. But if there is a tree or large bush within reach, it is only a matter of time before the moist soil around the crack lures the roots into the pipe and clogs it up. These roots can often be cut out by a sewer machine (sewer snake) with the proper root cutter head, but they will always grow back as long as the crack remains or the plant is alive.

We will not only be able to diagnose this properly to see exactly what is going on, we can handle any repairs that need to be made as well so that this doesn’t happen again.

Sewer Line Repair

Whether you only need a small sewer line spot repair or a full sewer line replacement (re-pipe) under the home, Legacy Plumbing is the company to call. Our expert plumbing technicians will thoroughly examine your sewer and drainage system to determine exactly the best plan of action.

Options include trenchless pipe repair, tunneling, spot repair, or trenching. Our trained and experienced sewer line professional can recommend the repair method that is best for you.

Trenchless pipe repair

Trenchless pipe repair is a faster and more landscape-friendly option that only requires a few access points. Our trenchless sewer pipe replacement has saved our customers thousands of dollars and valuable time by avoiding a massive excavation of their property.

Spot Repair​

A spot repair is performed if only a single fitting has to be repaired. We use locating equipment to pinpoint the exact spot. Then, we hand-dig down to the pipe, cut out the broken fitting, and replace it with a new one. If the spot is underneath a slab and tunneling isn’t the best option, we can penetrate the slab precisely where we need to in order to make the repair.

Tunneling

Tunneling is often the best way to replace pipes that are damaged underneath the slab of a home. All of our tunnels are hand-dug. The new PVC pipes we install are anchored to the concrete slab above with steel hangers to make sure it doesn’t move again.

Trenching ​

Trenching is how we typically go about replacing the main sewer line in the yard. We dig the entire trench by hand and backfill everything after the job is complete. We generally are able to preserve the sod and any landscaping that may have to be disturbed. You can rest assured that Legacy Plumbing will take care of your property and get the job completed in a fast and efficient manner.

So if you need a sewer line replacement or repair, contact Legacy Plumbing and a professional will help diagnose the problems in your sewer line and recommend the repair method that is best for you.

Luis was here today to fix a clogged drain and low water pressure in the bathroom. He was knowledgeable and courteous telling us exactly what he was doing to take care of our drain and how to manage our faucet aerator. Before leaving, Luis provided a complimentary inspection of our water heater and outdoor faucet water pressure providing more pertinent information along the way. On inspecting the kitchen sink faucet, he repaired a small drip. We were more than happy with Luis's work and will be calling Legacy Plumbing again for our plumbing needs.

Great experience with this company! We had a sewer leak under our slab. After extensive evaluation of the problem, Wayne explained in detail the options for repair. He and Schuyler took great care to protect the house while repairs were completed. It was a difficult repair, but they remained positive and were very personable throughout. The whole procedure was conducted professionally and with good humor. I would recommend this company to anyone!
