Pipe scaling is a term that refers to the build-up of minerals and rust from the inner linings of pipes. Some of the most common minerals that build up are calcium carbonate and magnesium. With metal pipes, slight scaling can be beneficial to prevent corrosion. Allowing the scaling to build up will decrease the amount of water that can flow through your pipes and will prevent a lot of damage to your plumbing system.
Cast iron pipes tend to have more severe scaling because their inner surfaces become coated with iron oxide as well as calcium and magnesium salts. When a pipe develops a thick, uneven layer of mineral and rust deposits, it begins to snag any solids and grime that flow past the rough sections. Eventually, the pipe becomes clogged or blocked. Luckily, descaling is a good way to clear pipes and restore them to working condition.
What Is Pipe Descaling?
Pipe descaling is the removal of accumulated minerals and rust from the inner surfaces of water, drainage, or sewer pipes. Descaling can also remove smaller roots that have grown inside the pipes. It is an important and necessary plumbing procedure in places where the water supply is full of minerals like calcium or magnesium carbonates.
There are two main methods used to do pipe descaling. The first is by scrubbing the pipes with abrasive tools or materials. The second is with the use of chemicals.
How It's Done
How a plumber chooses to descale a pipe depends on the extent of the blockage and scale buildup in the pipes. It also depends on whether the pipes carry clean water or wastewater.
After a plumber does a thorough inspection of the pipes, they will recommend the most effective _descaling_ technique. Our preferred method is Mechanical Descaling due to it being an environmentally responsible non-polluting alternative to chemical descaling.
