Trenchless sewer repair is sometimes referred to as pipe bursting. It is the process of digging an entry pit and an exit pit in the yard. Sewer Lines Only then uses a bursting head to pull the new line through the existing line. The old sewer line breaks away when the bursting head comes through making way for the new sewer line. The main reason people opt for trenchless sewer repairs is because it does not require digging up the yard. There are two holes on either end, but the entire length of the line does not need to be trenched. This is particularly helpful when there is extensive landscaping, concrete patios, etc. Although the actual process of trenching and trenchless sewer repair are similar in cost, there can be significant savings if the landscaping does not need to be replaced.
Keep in mind that trenchless sewer repair is not always your best bet. First of all, the city may not always allow it. Some cities don't allow it at all and others handle it on a case-by-case basis. In some cities, such as Denver, the city inspector usually makes the call on whether a particular job is a candidate for trenchless sewer repair. As mentioned above, when there is extensive landscaping or concrete work to do be, that is a strong argument for being able to do it. The second factor to consider is the condition of the current line. When pulling the new sewer line through it will mimic the existing line. Therefore, if there are bellies or low spots, the new line will have the same issues. In fact, many cities require that the homeowner sign a hold harmless agreement stating that they are aware of the risks associated with doing trenchless sewer repair. That said, it can be a great option in some cases.
