If you have a broken sewer pipe on your properly, then you have a wide variety of options available to you for repair. In some cases, repairs can be completed with the installation of a new internal liner. In this case, a new section of sewer line can also be installed through the old pipe. A traditional replacement can also be completed and it may be a good option if the sewer line is old or if it contains a large break. Traditional sewer line replacement may involve the digging of a new trench before the pipe is inserted. While it may not seem convenient to have your yard dug up for the purpose of replacing the sewer line, there are actually quite a few advantages to this.
Sharp Protrusions Are Minimized
Some sewer pipes may break or form holes due to the presence of sharp protrusions near the pipe. If the sewer pipe is secured near a level of bedrock, in rocky soil, near trees, or in an area where bones may be buried, then there are protrusions that can break the pipe. If tree roots caused the initial leak, then trench digging can remove them and move the roots back away from the new sewer pipe.
If tree roots are the specific issue, then preventative measures can be taken to prevent new leaks. Chemical agents like copper sulfate and potassium hydroxide can be spread around or near the new pipe. Also, the placement of a physical wood or metal barrier can be secured beneath and next to the pipe to keep roots from growing around the new installation.
If your sewer line sits near a bedrock slab or rocky soil that can force rocks to migrate near the sewer pipe, then a layer of sand can be placed around the sewer pipe. This is advisable for all new installations to keep the pipe protected from sharp objects. Pea gravel can also be used to create a bed around the pipe, but this may not cushion the sewer line as well if sharp rocks and other objects are seen in the area. Thankfully, clean sand fill is not required when a sewer pipe is being installed because fresh water will not pass through the pipe. This can help to reduce your costs with the use of general fill sand instead of rinsed or washed sand.
Deeper Trenches Can Be Created
If your sewer pipe formed cracks and breaks during the winter months, then it is possible that the original sewer line was not installed deep enough for your area. Sewer lines are installed underneath the frost line so that ice cannot place a great deal of stress on pipes during the winter months. The depth of the line is determined by the average level of frost that your area is likely to see.
For example, if you live in the state of New York, then the ground is likely to freeze between three and six feet below the earth. If the original sewer line contractor placed the pipe only about four feet below the earth, then ice that traveled below this depth would have placed significant amounts of stress on the pipe. Yearly freeze and thaw cycles likely weakened the pipe and caused the break.
A newly installed trench and sewer pipe can be created to better withstand the depth of ice in your area. Make sure to speak to your installation expert, someone from a place like Gold Seal Plumbing, about the common ice depths in your region so you can be sure that the pipe is installed below this depth. Also, the professional can work with you to choose the right piping material to reduce freezing issues in the future.
