Sewer line issues? It’s hard to know what is going on in the sewer line without a camera inspection. It could be tree roots, perhaps something was flushed down the toilet that shouldn’t have been flushed down the toilet. It could even be what know one likes to hear, a broken sewer line. Whatever the problem is, a sewer line inspection will take out the guess work. With the combination of a camera and a locating device we will know what and where the issue is. If you are in the process of buying a house that is build prior to 1980, I recommend a sewer line inspection.
Prior to about 1980 the main sewer line to a house was clay pipe. Clay sewer line is susceptible to tree root intrusions. When clay pipe was installed they used a sealant at the joints where the pipes meet. After about 7 years this sealant breaks down and when it does, it allows moisture to seep out of the pipe. Tree roots find this moisture and follow it to the source which is inside the sewer line. Given time the tree roots will grow breaking and collapsing the clay sewer line.
Houses built after about 1980 have PVC or plastic sewer lines. The advantage of PVC over Clay is the PVC (if installed correctly) is sealed. There is no moisture on the outside of the pipe for trees to find so they don’t attempt to enter the sewer line. How do I know if I have clay or PVC sewer lines? As a rule of thumb 1980 is year it was changed form clay to PVC. There is a large overlap in these years. I have seen PVC as early as 1977 and clay pipe as late as 1982. A way to see it you have clay or PVC is to look in the crawl space or basement. If you see PVC pipe then most likely the main sewer line is PVC. If you see cast iron pipe then most likely it is clay sewer pipe.
