Let me explain a bit more about my problem. 54 year old house. The builder used sub standard cast iron in the drainage. The 4" house mnain 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 kinow 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. That's when
Rooter Man of Sarasota and Gulf Coast Florida suggested relining the main, (see image). It took a dayto 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 and the best poart 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.
I was amazed at the equipment RooterMan had outside my place. Hi tech stuff that took a technician to run it. 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 reeplace 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, Tom
