I don't know but there is some mojor problem with my sewer main line. I think it is severly clogged and think that only a professional can fixed it. Which is the best trenchless sewer repairs in NJ.

A good quality roofer, exterior remodeler, plumber or landscaper.

Looks like you could use help of a good plumber or handy man who knows how to work with PVC piping. It's not complicated job, but there are few technics to it. Hope it helps.

Hello,

We do not work with a lot of upholstery so I'm not sure.

Thank you for asking though. 

not sure about the product used in your home. we usually pack the joint with oakum. then we use hydrolic cement (water plug). followed by tar on the outside. hope this helps. email with any questions. kevin@mrplumbing.com

You definitely should not have any leaking.  I suggest you call a plumber to come look at the issue.
