How Does Pipe Relining Work?
Wondering how pipe relining works to restore the proper functioning of any plumbing system? We break it down for you through this extensive guide on the topic.
Have you just found a malfunctioning drain at home but don’t know what to do about it? You’re at the right place!
Traditional drain repair methods are, of course, available and that may have popped up in your mind first. But such repairs might not be durable and long-lasting enough since the material used is not adequately resistant to regular wear and tear. Plus, they would need a lot of digging, which can affect the landscape substantially.
This is why the modern pipe relining procedure is the best to go for, as it uses highly durable material and requires minimal or no digging. But to know whether this would be the most suitable option for you, it’s essential to be aware of the nitty-gritty of the procedure.
That’s why we’ve curated this detailed guide for you. Go on and give it a read.
Notably, there are various approaches and methods of pipe relining as adopted by experts in the field. But the one that we’ll be dealing with in this article is the most widely used technique to date. In this method, plumbing professionals basically use a resin solution to design another pipe inside the broken or cracked one.
To understand how this works, let’s look at the various steps involved.
Professionals begin the job by assessing the plumbing network since it’s indispensable to any plumbing repair work. Since pipe relining involves internal repair, a drain camera is usually inserted into the pipe to ascertain the presence of any blockages, breakage, missing sections, or misalignments.
The real-time footage captured by the camera helps identify the exact problem and the spot where it’s located.
Following this, a hydro-jetting procedure is used to clean the drain connected to the pipe. It helps flush out years of debris, obstructions, scale and other substances accumulated in the passages. This way, the pipe is made ready for lining.
The professionals then create a customised liner and bladder as per the dimensions of the affected pipe. This design also includes any junctions or bends in the pipe.
Once the two customised parts are ready for installation, the liner is soaked in a high-quality epoxy resin, while the bladder is placed within the pipe in an uninflated form.
At this point, the professionals attach a rope to both ends of the liner. It is then used for pulling the liner in the right position within the pipe with the help of some access points.
A drain camera is also utilised for the process to ensure that the positioning is perfect. Next, they inflate the bladder, and the air blows out the liner to help it seal on the inner lining of the original pipe.
This results in the creation of another pipe that covers any cracks, breaks, or other damages in the old one. Note that the bladder stays inflated until the resin is cured, making the pipe tougher and harder. Finally, the bladder is deflated and pulled out to leave a new and perfectly watertight pipe.
After the relining is complete, the plumbing professionals use a CCTV camera again to ascertain that the sealing and installation are performed correctly.
By now, you must’ve understood that pipe relining is a highly advanced procedure. But it’s also essential to know what you’ll get by going for this method of pipe repair. Here’s our rundown on the various benefits of pipe relining.
Since the procedure involves minimal digging, it doesn’t affect any traffic around the spot of the repair. That’s why this method is also suitable for public buildings and parks that require pipe repair.
Furthermore, the procedure will not alter the look of the landscape, flooring, or fencing in homes. A maintenance hole is generally used for the filling, but even in cases where more passage is needed, the disruption to the landscape is minor.
Pipe relining is a much quicker procedure than pipe replacement. That’s because all the time that goes into soil digging, removing the original pipes, and replacing them is eliminated. It will take just around two hours to fix the pipe through pipe relining. And considering the advanced drying techniques used nowadays, the time might be reduced further.
Since CCTV cameras are used at the start, the professionals can not only assess the damage level but also know the exact cause of the break or blockage. Considering this, they can also decide whether they should act upon the broken or blocked pipe or the agent bringing about the damage.
Compared to the traditional procedure of overhauling the whole pipe, the pipe relining system offers you the scope of fixing just the damaged portions. And in case the problem arises due to a single hole at one spot in the pipe, professionals can conduct a one-meter relining to sort it out. Hence, you never have to pay for repairing the entire length of the pipe.
You must keep in mind that pipe relining is not only useful for broken drains, but it is equally effective for fixing those that are blocked. Additionally, the new pipe provides a much smoother surface to aid drainage since deposits can’t stick to it.
The cost would, of course, depend on the amount of damage that needs to be addressed. But the procedure is still a cheaper alternative when you consider the expenses of replacing or fixing parts that get damaged during excavation.
This trenchless procedure of repairing pipes can be expected to last for as long as 50 years. But to get such results, you’ll have to ensure that the pipes and the surrounding plumbing system are subjected to routine check-ups.
Generally, plumbing companies offer an installation warranty of 10 years on the liners used for the procedure. But apart from that, some of them offer a 50-year warranty on the service, which enhances its reliability further.
This procedure can be applied for several pipes such as stormwater pipes, water mains, fire service pipelines, pool pipes, concrete pipes, copper lines and sewer lines. Thus, you can rest assured that professionals can rectify most pipe damages using this technique.
Due to the use of ultraviolet light in the curing process, the pipes may sometimes release certain chemicals that are harmful to the soil. However, expert workmanship and design can eliminate or reduce this problem.
Speaking of the resin used, it is tested to be perfectly environment-friendly. That’s why your decision to reline one or more pipes doesn’t pose any threat to the environment.
Relining a pipe that has completely or partially collapsed will require special equipment such as robotic cutters. This advanced tool helps grind away the collapsed sections of the pipe so that its internal diameter can be reopened.
If the company you’re hiring for the job has such equipment, they’ll very well be able to handle these issues. So, you must discuss this with them beforehand if you’re faced with such an issue.
Now that you’ve learnt all about the procedure, it’s high time you call a reliable plumbing service to reline the damaged pipe(s) at home. One decision will keep your pipes perfectly secured against any wear and tear in future.
Most plumbing companies across the country make use of different advanced technologies to address any plumbing issue.
As such, finding one that offers quality pipe relining services won’t be difficult at all. Just search online for the nearest plumbing company that has received high ratings and reviews and get in touch with them. They’ll take care of it all.
