Trenchless Sewer Replacement
There is a lot of talk these days about trenchless sewer replacement, but many homeowners are left in the dark as to what it is or how it works. It seems like such an odd idea, many do not even know where to start when asking a plumber about the option. It seems like it might be a gimmick, but it really does work. Trenchless sewer replacement is a great technique that saves time, money, and reduces the mess. Plumbing contractors have special training and equipment to do this and the concept itself really is not too difficult to get a full understanding of.
The trenchless sewer replacement might be called by a variety of different things including “no dig” or “digless” or some other branded names. It all works in the same manner, though. Two holes are dog—one at each end of the sewer system–one at the exit path at the end of the property line where the sewer connects with the main line and one right by the house where the sewer system hooks up to the building. Once the holes are dug, a high tension steel cable is snaked through the existing sewer pipe. A special attachment called a hardened bursting head is attached to one end of the cable, near where the line connects to the home.
Next, a new, polyethylene sewer pipe is attached to rear of the bursting head. A hydraulic system is set up at the end where the hole is dug at the edge of the property line and it is attached to the cable. That hydraulic system pulls the head and attached pipe from the end where the hole is by the house. The head presses hard against the old sewer pipe, bursting it open and pressing the fragments into the surrounding dirt. The polyethylene pipe follows the bursting head, acting as a replacement for the old pipe that was just broken apart. The new pipe follows all the way through the hole to where it connects to the main sewer line. Then, connections are made to the house and the main line. After that, the equipment is removed and holes are filled in once testing has completed.
The Cost of Trenchless Sewer replacement usually ends up being comparable to or less than traditional trenched sewer replacement. While the equipment is costly, you do not need somewhere there to dig up the entire trench. That means you also do not need someone to take the time to fill in the trench, just the hole near the house and at the end of the property line. There is also no hauling and disposal fee for the old sewer pipe. Exact costs for trenchless sewer replacement vary by length of pipe to replaced, certain regulatory requirements, and the area that one is in. Someone with clay soil may end up paying differently than someone with fertile dirt soil surrounding the sewer line. Typically, the cost ends up being somewhere between $100 and $200 per foot. The trenchless sewer replacement also means that there is less landscaping to be repaired and overall less time to do the work. Those savings in costs are passed on to the customer.
The average time to pull and burst pipe usually takes no more than an hour or two. However, there are several variables that can cause this process to go longer including soil density, clogs in existing pipes from roots, or such. In any event, the entire process is usually done within one to two days narring any extenuating circumstances.
The most common type of pipe used to replace existing sewer lines is high density polyethylene pipe, or HDPP. This type of pipe tends to fair better than traditional clay pipes as well as cast iron or PVC plastic pipes. HDPP has been engineered to resist corrosion and it is fused together instead of glued together. This makes the joint stronger than other parts of the pipe, which is the opposite of other types of sewer lines. That makes it virtually leak proof and highly flexible. HDPP is expected to last and has been tested in labs to last for more than 200 years. So, once you replace the sewer line with this type of piping, you should not have to replace it again within your lifetime. As such, it can also be something used to increase the value of a property when it is time to move or sell.
Another great factor with trenchless sewer replacement is that the pipe can easily be replaced if it runs under gardens, patios, sidewalks or driveways. That cuts down time and saves on cost. It also means less of a mess.
When investigating options for sewer replacement, be sure to ask your plumbing contractor about trenchless sewer replacement. Make sure to look at the various options. You want to know how much the cost for your different options are, what the timeline is, and what materials are going to be used. You also want to ask about the warranty for the work and the materials. Be sure that the plumber has the proper insurance and has all the necessary permits to complete the work on your premises.
