During a sewer line replacement, many tasks must be performed in order to ensure a properly-flowing, problem free line for many years to come. There is far more to sewer line replacement than simply digging up your yard and ripping out the old piping. If certain precautions are not taken, even a new sewer line can present problems in the years to come, often leading to more costly repairs and warranty calls. We employ only the most experienced and professional sewer line experts, therefore eliminating any need for worry after your installation.

After your old, decaying sewer line is removed, it is time to begin installing your new PVC line. After connecting to the sewer exit at your home, we then run new piping all the way to the county/city tap. The "tap" is where your sewer line meets the county/city's main, and it is where your responsibility ends. This tap can be anywhere from 4 to 25 feet deep, and is normally made of concrete. New plumbing code requirements dictate that a cleanout be installed every 50 feet of your new sewer line, beginning with one near the home. From this house-located cleanout, another is installed every 50 feet to the end of your line. These are access points for any necessary future maintenance, such as cleaning or camera inspection. The cleanout itself is a vertical piece of PVC that extends vertically from the sewer line above the surface of the ground, usually just a few inches above the surface. Each one is topped with a removable cap to prevent debris from entering the line.
In addition to cleanout installations, the pipe joints must be properly connected. Although a type of glue is used, the process itself is called solvent welding. It is termed such because the glue actually melts the surfaces of the PVC pipe together in a way that strengthens the joints greater than simply using a mechanical coupling. Before the glue is used, the PVC must be prepared with primer to remove any dirt or chemicals. As long as each joint is connected correctly, the possibility of root intrusion is virtually eliminated, as is the chance of leaks.
Two things must be done at the end of each installation. The pipe must be sloped properly, and it must be bedded in. Sloping the pipe refers to giving the sewer line enough angle, or fall, to facilitate proper drainage and flow. The code requirement is 1/8" of slope per every foot of 3-4" sewer line. This is only the minimum, however, and more slope is never a bad thing. Bedding in the sewer line consists of placing hard material or substrate beneath the completed sewer piping to ensure that it does not bend, or belly, over time. A belly is a dip in part of the sewer line, allowing water and waste to collect in the lower part, causing blockages. Bedding in the sewer line is an extremely important part of the complete installation, and is often overlooked. The material used can be gravel, hard earth, sand, or any other material that will support the weight of not only the sewer line itself, but also all of the earth above it to the surface. Bellies are common problems in sewers that have not been bedded properly.
If all these procedures are followed correctly, you will be left with a quality sewer line that will last for decades to come. We guarantee a top-level installation conforming to these regulations, and back it all with a 5-year warranty.
