Is My Home a Candidate for Trenchless Sewer Line Replacement?

If you have been experiencing issues with your old sewer lines, you may be researching options for replacement. One of the more appealing options available is trenchless sewer line replacement, where your old pipes are left in the ground and new piping is inserted without needing to dig up your yard. However, not all homes are ideal candidates for this option and it may be better to opt for traditional sewer pipe installation. Here are some of the criteria that could make trenchless sewer line a poor solution for certain homes:

  • Poor grade. Trenchless sewer line replacements require a certain grade to make them functional. Installing these pipes in the wrong grade conditions could mean backup problems and future sewer line repair expenses.
  • Local regulations. Trenchless systems are usually installed by bursting the old pipes that are in the ground and inserting a new tube in their path. Some localities may not allow this method, especially if you have old pipes that may contain lead.
  • Tree root issues. If you want to change the path of your pipes to avoid future tree root invasions into your sewer lines, trenchless replacement may not be an option.
  • Soil conditions. Not all soil conditions are conducive to the type of sewer lines used in trenchless replacement.

It is important to know all your options when it comes to sewer line replacement. To determine whether trenchless or traditional replacement would be best for your home, call your local sewer service company for a thorough inspection and evaluation. Your local sewer professionals can recommend the best options for changing the sewer lines in your home that will best meet your needs.

Can Any Sewer Line Be Replaced Using Trenchless Technology?

If you’ve ever seen a sewer line being replaced or repaired in the traditional method, you know it can require a substantial amount of digging and can do damage to surrounding landscaping. For many decades, sewer pipes were dug up, either by hand or with a backhoe, to remove old pies and install new ones. New technology now allows sewer lines to be replaced with a trenchless method, which requires very little digging. Still, there are some circumstances in which trenchless repair isn’t feasible.

When Trenchless Sewer Replacement Is Not An Option

Trenchless sewer line replacement uses a bursting head to shatter the existing pipe, while pulling a new pipe into place. This only requires digging a small hole to insert the equipment into the existing sewer line, causing very little disruption to the homeowner’s property. While this is becoming the preferred method for sewer line replacements, there are certain sewer pipes which will require the traditional digging method, such as:

–        Sewer lines with a poor grade

–        Pipes located too close to gas or utility lines

–        Pipes that have an extreme tree root infestation

–        Certain soil conditions or municipality regulations

In most cases, trenchless sewer line replacement offers a convenient way to have a new sewer line installed without the mess of digging. If you are considering replacing any of your existing sewer lines, before deciding which method to use, have your sewer line inspected by a qualified sewer professional.  Your sewer professional can determine whether your property is a good candidate for trenchless sewer repair, or advise you about other available sewer line replacement options.

Trenchless Sewer Line Repair

No one wants to have to undergo a sewer line repair or replacement. For one thing, they can be costly, up to $20,000 depending on the nature and extent of the problem. For another, they are very disruptive, especially when a backhoe has to be taken to the whole back yard to get to the target pipes, which can lie under the garage, patio or new lawn you just installed.

Well, at least now there is relief on one front. Sewer septic companies have begun offering trenchless sewer line repair, a process which involves very little digging, if any.

How does it work?  Basically, the sewer septic professional will go through one or two entry points with a long narrow probe and fix the damaged pipe using one of two techniques:

Pipe Lining – In this type of repair, a flexible tube coated with resin is pulled through the damage pipe and then inflated. The resin then hardens to form a new tube inside the pipe, diminishing its diameter by a mere quarter inch.

Pipe Bursting – In this type of trenchless repair, a new pipe is drawn through the old one, bursting it in the process. With this method, there is no reduction in the diameter of the sewer line.

Both of the above methods are more costly than traditional sewer line repair or replacement, costing between three thousand and twenty thousand dollars per pipe section.  However, if it means that you do not have to dig up the driveway, garage or entire lawn, it might well be worth it. The only way to know for sure if this option works for you is to contact your local septic sewer contractor for a consultation.

Trenchless Sewer Line Replacement

Replacing your sewer line is an expensive, messy job that usually entails digging a trench through your yard so that the new sewer lateral can be installed.  For many homeowners, the process can cause a significant disruption of their landscaping and in some cases can even mean digging up driveways, sidewalks, and even garages.  Before you start digging, talk to your sewer-septic contractor about your trenchless sewer line repair or replacement options.

New techniques have been developed for repair or replacement of sewer lines with a minimum of destructive digging.  Two popular techniques are pipe bursting and pipe lining.

With pipe bursting, a new pipe is installed by dragging it through the existing sewer pipe.  A pipe bursting head is installed on the leading edge of the new pipe and as it is dragged through the old pipe, the bursting head breaks up the old sewer line.  The pieces of the old sewer line are left in place around the new pipe.

A hole needs to be dug at each end of the sewer line, but the rest of your yard can usually be left undisturbed.  One exception is that a hole will need to be dug at any bends or turns in the sewer pipe.  Pipe bursting only works in a straight line so if you have any turns or bends in your sewer lateral, a separate pipe will need to be installed in each straight leg and a connection made at the bend.

Pipe lining is another option for repairing a sewer line without extensive digging.  A soft flexible tube coated with cement is pulled through the existing pipe and inflated so that it presses against and adheres to the walls of the old sewer pipe.  The tube hardens in place and creates a lining inside your existing sewer lateral.

Your plumber or sewer-septic contractor can help you decide which sewer line replacement option is best for you.

Should You Repair Or Replace a Sewer Line?

A broken, collapsed, or totally clogged sewer line is serious problem that needs immediate attention.  You will need an experienced plumbing contractor or sewer-septic contractor that handles sewer and drain line installation and  repair to identify the source of the problem and help you determine whether to repair the drain line or whether a replacement pipe will be necessary.

A sewer line that clogs frequently or leaks probably has cracks that are infiltrated by tree roots.  These roots can be cleared, but unless you address the underlying problem they will grow back and the problem will reoccur.

If the pipe is leaking in one area, there is a good chance that leaks or cracks will soon form in other areas of the pipe.  If you have a broken or collapsed line, you will need to know what caused the problem and the condition of the rest of the pipe.

First, have any clogged lines cleared by a mechanical rooter or high pressure hydro-jetting, then have a video camera inspection done of the inside of the pipe.  Your sewer-septic technician or plumber will run a small video camera through the accessible area of the pipe and be able to let you see the condition of the inside of the pipe.

You will know from the video inspection whether one section of the pipe can be repaired or whether it should be replaced.  If the damage is limited to one section and the rest of the pipe is in good shape, your plumber or sewer-septic professional can probably repair it. On the other hand, cracks and damage throughout the line means that the entire pipe should be replaced.

Trenchless Sewer Line or Water Service Line Replacement

A broken or leaking water or sewer line can be very messy to repair or replace.  Your sewer line and water service lines are buried underground and run from your house to the municipal sewer or water lines that run along the street in front you your home.  If the line cannot be repaired, it will need to be replaced which normally involves digging a trench from your house to the street.

Unfortunately, sometimes the sewer or water service lines run under a driveway, walkway, or other landscaping feature.  Digging the necessary trench tears up your yard, bushes, flowers, and in some cases, your driveway, walkway, and landscaping features.

Fortunately, in recent years a new trenchless pipe replacement technique has been developed that allows your plumber or sewer-septic professional to replace your pipe without extensive digging.  Also call pipe bursting, trenchless pipe replacement usually only requires two small holes to be dug.  One hole is dug where the pipe connects to the municipal water or sewer system, and the other end is dug where pipe connects to the home.

The trenchless pipe replacement machine pulls a new pipe through the ground where your old pipe was buried.  A new polyethylene pipe is attached to a steel bursting head and a chain or cable is hooked the bursting head.  The cable is run through the old pipe and attached to a machine that pulls the new pipe through the old pipe.

As the new pipe is pulled into place, the bursting head breaks up or “bursts” the old pipe which is left in the ground.  Once the new pipe is in place, the ends are connected to the home and to the municipal water or sewer service.
