Introduction
Pipes that are not properly maintained can become a significant source of water damage and mold. In fact, they can even cause leaks and plumbing problems that affect your home’s structural integrity. So what’s the best way to deal with this? Pipe relining is an effective solution for restoring your pipes without having to dig them up or replace them completely.
What Happens In Sewer Pipe Relining?
A pipe relining Sydney procedure is effective because in their process they use a high-strength epoxy to patch damaged pipes. The material is injected into the interior of the pipe, which can then be left to harden and cure.
The epoxy resin used in pipe relining has been specially formulated for this purpose, with different types available depending on whether you want to repair or replace your sewer system.
With this method of repair, there are no messy dig-ups or temporary repairs—only one visit from a professional plumber who will inject the resin into the damaged section of your sewer line and leave it there until it sets properly.
How Does A Sewer Pipe Lining Work?
- For the sewer pipe relining process, a new pipe is inserted inside the old one. The new pipe is made of a flexible material that can expand and contract to accommodate any changes in temperature, pressure, or water flow.
- The new pipe is installed in lengths of about 2 feet (60 cm) at a time. For example, if you have an 8-inch diameter pipe that needs relining and there are two joints between it and other pipes—which means two joints where sections of your sewer system connect—the first section would be cut into pieces roughly 4 feet long (1 m). These pieces would then be inserted into both joints and connected with epoxy glue before being inflated with air; this expands them until they fill up the space between each joint.
How Long Does It Take To Reline A Sewer Line?
How long it takes to reline a sewer line depends on several factors:
- The size of the pipe that needs to be relined
- The location of the pipe (whether it’s in a manhole or underground)
- The difficulty of the job (how many joints, bends and connections there are)
- Whether you have a lot of debris in your line
What Is The Cost Of Relining A Pipe?
The cost of relining a pipe will depend on the length and size of your pipes, as well as their location. It’s much less than the cost of replacing your pipes entirely (full repiping).
The average cost for relining a 4” cast iron drain pipe is $2,500-$3,500. If you need an 8” pipe, expect to pay between $4,500-$7000 on average. For large diameter (10”) sewer lines or those made from PVC or ABS plastic, expect to pay in the range of $9000-$13000 on average.
You don’t have to do a full repiping if the problem is just with your sewer line or a smaller section.
- What is sewer pipe relining?
- The first step of a sewer pipe relining process is to insert a new liner inside the existing pipe. This can be done by either pulling out the old liner or inserting it from the outside, depending on your specific situation. Then, you will push back in any debris or water that may be stuck inside of the old pipes. Finally, you’ll fill in any gaps with cement and allow everything to dry for about 24 hours before flushing out excess water with high-pressured air guns.*
This method is helpful if:
- You don’t have enough room to install new pipe or replace damaged sections (e.g., if there are too many bends)
- Your current pipes are small enough that repiping isn’t necessary
Conclusion
Sewer pipe relining is a great way to solve the problem of a worn-out sewer line without having to do a full repipe or trenchless repair. Sewer pipe lining is a relatively simple process that can save homeowners thousands of dollars and also helps prevent damage to your yard and landscaping. It’s important to know that this method won’t work if you have tree roots growing in your sewer lines, so if you do then check out our blog post about root infiltration here!
