DOES YOUR CAST-IRON SEWER NEED PIPE REHABILITATION?
Pipe rehabilitation or descaling restores old cast-iron pipes’ inner surface to ensure better drainage. Cast-iron drain pipes rust overtime and create flaky residues that occupy the inner drain flow space. Due to such deterioration over time, drain flow space decreases hence the increase in the probability of drain clogs.
DESCALING PROCESS & DETAILS
Pipe rehabilitation removes the rusty scales, that have accumulated inside cast-iron pipes over time. Chain link with steel nail scrapers spins in high-speed therefore creating friction that files and scrapes the rust off the pipes. A constant high-pressure stream of water flushes rust-debris that fall to the bottom of the pipe. This procedure opens up the pipe for better flow. As a result of the removal of scales, the old cast-iron pipe resembles a new one in its look, flow, and functionality.
The descaling process typically starts at the end of the drain system and continues upward toward the opening. Descaling can be a tedious process of filing the clog-creating obstructions, hydro-jetting the loose scales, and video inspecting to ensure quality work. Therefore, descaling takes patience and care and if performed correctly should be time-consuming.
A cable inside a vinyl sleeve is the basic structure of a descaling machine. That cable is attached to the chain-link-head, tightly rigged chains with steel nail scrapers on each chain link. Inside the sleeve, the cable turns in high revolutions and the pressured water runs constantly so the cable stays functioning and lubricated. The machine has a high torque capability and its speed can be varied depending on the job.
Cast-iron pipes show signs of excessive scale build up after daily use for about 35-50 years. Implementation of a thorough pipe rehabilitation process adds another 35-50 years of use if there are no structural damages to such pipes. Therefore descaling extends the life of drains pipes and helps homeowners avoid costly drain replacements. Pipe rehabilitation eliminates those flaky obstructions that trap deposits so the cast-iron pipe functions better. In conclusion, the propensity of drains clogging is minimized.
