Replace Sewer Line
If your house was built before the 1970’s then the sewer line is probably a cast iron, clay, or cement. These lines are brittle and may begin to crack due to stresses. Once a hair line crack has formed, moisture seeps out attracting tree roots. Once this occurs, it is not long before a root ball begins to form inside your sewer line restricting the flow.
PVC had begun its day view in the early 1970’s with a life expectancy of 100 years. PVC is a strong material and unlike clay it has the ability to flex if subjected to stress. PVC is made with different wall thicknesses referred to as schedules. (i.e. sch 20, sch 40) Louisiana plumbing code allows for a thinner wall PVC pipe to be run from the house to the city sewer. Plumbers refer to this pipe as sewer pipe. Sch 40 pipe is always recommended for underground sewer lines. At Mock Plumbing, thin wall pipe is not used on anything. Sch 40 PVC pipe is approximately $0.50 more per foot and is worth every penny. A sch 40 PVC pipe has approximately twice the strength of that of thin wall.
Another factor in all types of construction to consider is workmanship. For example, most plumbers will dig a trench, throw the sewer pipe in and begin to cover with dirt. If the pipe is not properly supported a belly or dip forms in the sewer line. This allows for solids to collect at the bottom of these bellies and before you know it a clog will form. Mock Plumbing takes great pride in what we do and are willing to back up all sewer line re-routes with a ten year warranty.
Having to replace a sewer line is one of the more costly and unexpected plumbing repairs a home owner may face. There are several factors that will determine the cost, but you can expect to pay anywhere from $1,500 to $2,500 in the Baton Rouge area.
