I am considering having a cured in place pipe relinging done in my leaking sewer line. The sewer line runs under a slap. Is this a good way to go? WHAT WOULD THE WARRANTY BE FOR THIS?

Let me explain a bit more about my drainage problem and how I repaired it. 54 year old house. The builder used sub standard cast iron in the drainage. The 4" house main was completely ate up on the bottom of the pipe , blocked with roots and welling up in my living room floor. I was sure that the main had broke in two and I would have to jack hammer up the floor and tunnel under the foundation to transition to PVC, pick up the back bath and move the main outside the house but I had to know what was going on under the slab so a friend suggested running a camera down there. There was no distinct break in the main, however,it was completely ate up on the bottom. That's when Rooter Man of Sarasota and Gulf Coast Florida suggested relining the main, (see image). It took a day to clear the roots and pressure jet clean the main. Next day they came back and relined the main with epoxy. I now have a sewer main that will out last me, (50 year guarantee) and the best part is that I didn't have to, tear up my house and the cost was under half of what I figured to take the main outside around the house. Another bonus was that it was done without tearing up or disturbing my house. When they were finished I kept a piece of the epoxy liner to check it out. It was white and had the same thickness of Schedule#40 PVC.
I was amazed at the equipment RooterMan had outside my place. The equipment he had cost upwards of $100,000.00. Hi tech stuff that took a technician to run it. There were 3 men and 2 trucks to do the job. And it was completed in two days. Lottsa difference from the old days when I went out on a sewer call with a Ridged K-60 Sewer Machine and a ladder to get to the roof vent. I just wanted to point out that there's another option besides replacing drainage that the years have ruined. If your pipes are a candidate for a reline job I strongly suggest you look into it before you decide to replace the drainage pipes. I did and saved a bundle in addition to keeping my home intact. Just thought I would share that with you all. Regards and thank you for rating my answer, Tom

Make sure you have a good reputable company doing the work. The curing process is what can make or break a good lining job. There are two ways a CIPP liner is cured, water and steam. Steam is much quicker because it's easier to heat up and pressurize. The pressure is what pushes the liner tight against the existing pipe and the heat is what cures the styrene. If you lose pressure during the curing process, the liner will collapse and if you lose heat, the liner will be weak. Water works the same way as steam only it takes head pressure to push it against the existing pipe and a long time to heat the water in the pipe up to the temperature required for curing. When done properly you will have one section of pipe with no joints all the way from your house to the main that is just as strong as PVC.
