To better understand our testing process, let’s jump into how a successful sewer system runs. 

When you think of your sewer system, the best way to visualize it is as a tree. You start with the tree’s trunk. This is the main line that stretches from the city’s sewer, either in the street or alley, to the furthest drain in your home. Next would be the branches. Each room with a drain located inside of it has a branch line that ties them into the main trunk line that stretches across the entire house. Finally they need to breathe which are the pipes that shoot up your walls piercing through the roof, these are referred to as vent stacks.
