I posted my problem earlier. I believe the guy who worked on my bathroom clogged my tub with mortor or grout - they were using my tub to fill & mix buckets of the stuff. He's being anal about coming & addressing the issue so I have to fix the problem myself & sue him for my expenses. First, is there any hope of me getting such a clog out myself? I've tried everything, including snaking the drain. The snake goes in the overflow opening about 3-4 feet comes to stop & it won't go any further. Can a plumber get such a clog out, or would they have to replace pipes? Would the camera clearly show the clog - would we be able to tell if it is mortor or grout material? And if so, how much can I expect to pay for video taping? Thanks for any advice!
