We paid a plumber $400 twice within 8 months to unclog our sewer pipe from the house to the street. About 60'. The third time we clogged we purchased 100' Vevor electric snake along with a Vevor 100' sewer pipe scope. About $600 total. With the scope we found the clog, and with this 100' Vevor sewer snake unclogged the pipe. Someone has been flushing lady stuff down the toilet. That problem hs been solved! Of course the plumber never told us this was the problem. He said roots were the problem. He could come every 8-12 months to clean out the roots, or dig up and fix our PVC sewer line. $400 every 8-10 months or a few thousand Pipe \"fix\", what deal. We now have the tools to see and fix any problem like that again. Great purchase and actually very little work to figure out the problem and fix.
