Occasional both of my toliets gurgle when I let water drain out of either bathtub. This has been going on a couple of months and is getting worse. I have checked the white pipe (clean out) coming out of the ground and the water is flowing fine. The house is two years old and has a septic tank. The septic tank failed last year and another 100 feet was added to the field lines.
Yesterday I checked the traps and pipes under the kitchen sink and one bath room. They both (all pipes & up in the pipe connected to the house) was covered in this black slimy stuff which I cleaned off. Is this normal? I saved a 2 inch piece of this stuff. When it dried it almost felt plastic. What is this? I have not checked the other two sinks. Any ideas of what else to check would be great.
Thanks
