Had a camera put down the sewer for an issue after where the PVC(10 years old) joins up with the terra-cotta. When plumber was going through PVC he noted “pitting” and said it was a sign that the wrong type PVC was installed and could cause an issue of collapse within the next 10 years.
I can’t find any info on this elsewhere, and had another plumber tell me that it’s not an issue.
I’m going to be renting the house out and don’t want any issues with plumbing backing up into the newly finished basement. We are already digging up the street to replace the terra-cotta from new PVC pipe to the main because it is filled with roots. Should we just replace the whole line including the “new PVC” at the same time, or is this a non issue that the one plumber is gouging me for.
No, my question is…. Is the “pitting” shown in the drain, a real concern. If I was “one of those”
Landlords I wouldnt be looking for answers. I’m already spending $20k on ripping up the street to solve the other issue. This is a 10yo pipe that shouldn’t have any issues.
One plumber said it was a concern. Another said it wasn’t a concern. My question is what do others think? Is this a problem that should not be happening 10 years into the playing of the pipe, or is this normal and can still expect another 40 years out of the pipe?
Hello Travis , that plumber is correct, it’s a thinner wall PVC and eventually will fail, unlike schedule 40, which is rated 40+ years. I was an estimator for Roto-Rooter back in the day and scoped a lot of lines.
Depending on the depth it can get up there in replacement price. My rec is to replace as soon as humanly possible. If it collapses, backups are eminent and rodding it out will be impossible unless you hire a jetting service.
Line replacements will require a permit and final inspection by code enforcement. Hope it works out…
As I said, I scoped a lot of lines, so yea, I can tell. As for what’s approved, depends on what’s allowed by code in the area. From the photo @tihle posted it appears to be schedule 30.
I’ve only been a licensed plumber for 38 years. Can you tell me again how this is schedule 30 PVC pipe? By the way, I’ve never seen schedule 30 used as DWV pipe anywhere in the three jurisdictions I’ve been licensed in.
Roto-rooter is the company that told me that this was an issue. I’m wondering if they are being trained incorrectly or they have a secret no one else knows?
