Sewer lines, just like any other pipe or drain in properties need preventive maintenance. Over the years, however, sewer lines will need relining, especially if the house has been in existence for so many years. Here are some of the common questions asked by homeowners about sewer line relining:
Q: What is sewer line relining?
A: In general, relining can be done for both drains and sewers. It is a process to repair problems like leaking, broken and blocked pipes. This method is done by inserting a textile liner which is coated with resin on the damaged part. This material will harden to strengthen the inner pipe.
Q: How long will it take for a sewer relining project?
A: The length of time for the installation of sewer liner varies depending on the lining method to be used. Moreover, method relining to be used depends on the condition of your sewer. If inversion method is to be applied, this will usually take two days to complete while pull in place lining and point repairs will be completed in a day.
Q: How many years will my new sewer or drain liner last?
A: Sewer and drain liners can last for a long time. These liners have a life expectancy of over 75 years.
Q: Are there cases when sewers can’t be relined or repaired?
A: Almost any sewer pipe material can be relined. These materials can be clay rock, PVC and cast iron. However, it will be impossible to reline a sewer line if it has already collapsed.
Q: Can I still use my water right after a new sewer line is installed?
A: Yes, but you have to restrict water usage during the curing process of the liner. After curing, you can resume the normal use of water.
Q: What kind of lining material will be used for a sewer line?
A: Lining material is a resin saturated polyester felt tube with PVC coating. For a smooth seamless surface, the polyester tube will be inverted to make the outer PVC coating becomes the inside of the sewer. For point repairs, material used is a two ply fiberglass sheet. This is the material of choice because this is designed to restore your sewer line’s structural integrity and be impermeable to roots.
Q: If my sewer line is cured in place, is it strong?
A: Yes. In fact, there have been millions of linear feet of in place materials curing has been installed on a global scale. These lines have lasted for decades and have survived even under corrosive environment. Moreover, with the absence of excavation, costs have been reduced.
Q: In terms of trenchless relining, how much area will be affected to access the sewer line?
A: With the technique to be used, digging will be in a minimum. It can also start and stop at any area of the line to ensure cost of materials is reduced.
Q: I am an environment advocate. Is sewer line relining safe for the environment?
A: Yes. The seamless sewer pipe will protect your sewer line from exfiltration and infiltration.
Q: I have been advised by my neighbors and friends to hire a contractor if I plan to have my sewer line relined to protect the landscape of my home so I can try the trenchless sewer line repair. Is this true?
A: A trenchless sewer relining method is your best option since it is cost effective, convenient and can be completed the shortest time possible. By now, most sewer lines and pipes have existed for so many years and have not been spared from calcification and intrusion from tree roots. Although traditional method with excavation can be done to fix your sewer line, this method can be expensive and time consuming. This technique can also damage your landscape, patio and driveway. With trenchless sewer repair, however, it is faster and easier. This is an advanced technology to reline a damaged sewer line.
Q: Why can’t I just have my sewer line cleaned?
A: Whether for drain or sewer pipe lines, cleaning might not be enough because if you use an electric drain cleaning machine, this is not a permanent solution. Especially if the cause is a root that has infiltrated the line, using the machine will just prune the root. In time, the tree root will grow back. If this will be ignored, a time will come that roots will become so large that they will be strong enough to break the pipe. Consequently, excavation might only be the solution.
Q: Will I know if there is a problem?
A: It is not really possible to detect a problem right away unless water in your toilet does not flush and it overflows. However, with proper preventive maintenance, these problems will be minimized.
Q: Can the liner be inserted from only one access point?
A: Yes. Our liner can be inserted through an existing cleanout or from a small excavation to install a new cleanout. The liner is open on both ends so there is no need to access the other end of the liner with a cutter.
Q: Can the relining be done from anywhere in my sewer pipe?
A: Yes. Date will be collected at first, including the specific sizes of bladder and liner tubes so they can be cut accordingly. Afterwards, the liner will be inserted and will be placed inside the pipe at the specific location. The liner is then inverted within the lateral pipe anywhere in the sewer line.
Q: How will I know that the liner is installed correctly and fully inverted?
A: A pressurized camera port will be used to view the liner. This will ensure that the liner bladder is where it should be inside the sewer line. With the right measurements, advanced lining tubes and a camera port, proper placement of the liner is ensured.
Q: How can I be assured that enough epoxy resin is used for relining my sewer line?
A: A suction system called a vacuum source will be used. This will be attached at the end of the translucent bladder. It will suction all the air from the liner then draw the epoxy resin through. Since the liner is translucent, it will be easier to check of the liner is completely saturated with resin and no damaged area is left without resin.
