What Is Pipe Descaling and How Does It Work?

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.

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.

How pipe descaling is done

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 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. Plumbers often use the following methods to remove scale buildup from pipes:

Hydro jetting and descaling

The plumber will choose this method to clear a pipe that is heavily clogged. First, they will blast a jet of highly pressurized water (water with a force of at least 3,500 pounds per square inch) to remove any blockage.

Next, the plumber will attach a descaling nozzle to the hydro jet, which will blast pressurized water through the nozzle. The descaling nozzle has a chain attached to it, much like a chainsaw. When pressurized water flows through the nozzle it rotates the chain, which scrubs the rust and mineral buildup from the pipe’s surface.

The descaling nozzle scrubs the pipe and washes away the debris at the same time.

Chemical descaling

A plumber may choose to remove scaling with the use of chemicals. They will choose this method if the pipe is relatively clear of other forms of blockage.

The plumber will simply flush an acidic chemical to dissolve the calcium and magnesium salts as well as the rust.

Why descaling is good for pipes

Modern descaling methods are a non-invasive way of clearing pipes, which means that a property owner gets to avoid the inconvenience and cost of dug-up yards and smashed walls.

Descaling also improves drainage and water flow while increasing the lifespan of the piping system.

It is also a convenient repair method because the occupants of a building can continue to use the facilities even as a plumber works on the pipe

If you are dealing with constantly backed-up drains or low water pressure, it is time to call the plumber. Chances are that they will find scaling in your pipes.
