Fly Outbreaks and Damaged Sewers Locating a Broken Sewer Line under a Slab-Part

摘要

Repeated outbreaks of phorid flies and drain flies are most commonly due to a dry trap. Some-times-however, they are caused by a sewer line break. The flies escape from the sewer lines and then breed in the organic "goo" that leaks from the broken pipe. Fly problems caused by broken sewer lines can be massive. They are uncontrollable unless and until the sewer line is repaired, which can cost thousands of dollars in homes and tens of thousands in commercial buildings. How do you determine if there is a sewer break under a slab? And how do you determine where breaks are located? You have three options: leak tests, smoke tests, and video inspection. All require the services of a plumber.
