Pipe Inspection is a must!
CAST IRON SEWER PIPES DAMAGED IN MANY FLORIDA HOMES OLDER THAN 30 YRS
Cast iron pipe has been a sewer line mainstay for decades and has an average lifespan of about 30 to 50 years. Unfortunately, the soil and salt water that seep into South Florida’s land often make it deteriorate even faster. As these problems progress, the pipes weaken and eventually needs to be replaced due to advanced deterioration or failure.
CAUSES OF CAST IRON SEWER PIPE FAILURE
Over time when metal pipes constantly come in contact with wastewater, the interior of cast iron pipe will eventually rust. When the rusting occurs on the interior of the cast iron pipe it reduces the flow of the sewer line. It will start building up, and then begin to reduce the interior diameter of the pipe. Furthermore, the rust will also create a rugged surface that will slow down the rate of the flow across the surface. When the rust becomes excessive it will lead to cracks and eventually broken pipes.
The real danger for cast iron pipes is corrosion. Wastewater flow creates a channel at the bottom of the pipe and if left untreated this will cause it to erode through the pipe and weaken the structure not only that but also could allow insects and other foreign objects to enter the line. In addition, the wastewater can leak through the pipe that eventually could cause bellies in the line that will lead to catastrophic collapse of the entire plumbing system.
The dangers of cast iron pipes that fail is that it allows raw sewage to seep into the soil below your house and can release harmful gasses back into your home. Over time these gasses could cause illnesses, such as allergies and other health conditions. Unfortunately, once the failures occur, repairs are not an option. The work will often require significant demolition. This can mean the replacement of floors, walls, fixtures, cabinetry and even finishes to be able to facilitate professional repairs. In addition, these broken pipes also become breeding grounds for insects, particularly cockroaches that make their nests within the pipes and could eventually find their way into your home
