After years of normal use, corrosion deposits adhere to the walls of the cast-iron pipe through a process called tuberculation. After 20-30 years, corrosion deposits usually have taken over 25 – 40 percent of the cast-iron pipe.
Every flush down the toilet, debris continues to slow down and form deposits along the sewer line. These deposits reduce the flow rate of the cast iron and eventually cause the drain to back up and/or fail.
When you call an ordinary plumber to inspect the cause of a sewer backup, the plumber will most likely run a drain camera through the sewer to inspect the condition of the pipe’s interior. More often than not, the plumber will see the corrosion and recommend a sewer replacement.
But, what the plumber may have failed to understand is that tuberculation can be removed, which will cost you less money to you the customer.
The majority of sewer and drain contractors don’t carry the specialized de-scaling equipment. Typically a sewer and drain contractor will recommend a solution based on their abilities and tools they own.
OUR DESCALING METHOD
We use a state of the art descaling machine which is called a Maxi-Miller Picote Machine. The Picote has many grinding chains are multi-use tools which are extremely effective at removing large build-ups of scale and more.
