Pipe Descaling
What is Limescale?
Limescale is often found as a hard deposit on the inner surface of old pipes and other surfaces where “hard water” has evaporated. It is usually the most common issue where pipe descaling is required to treat it.
In addition to being unsightly and hard to clean, limescale can seriously impair the operation and serviceability of a drain or sewer. If left, over time the problem can increase until the pipe’s diameter is significantly reduced.
What can you do when it comes to pipe descaling?
The build-up of limescale is tough to remove and in some cases, standard drain cleaning methods such as water jetting, will not work. In these instances, more specialist equipment or higher jetting pressures may be required.
Ultra-high jetting pressure machines, Warthog and chain flail spinning jet heads or even mechanical cutters are some options available to us to help you with this issue.

How to prevent limescale
Limescale prevention starts with managing the hardness of your water supply. In areas with hard water, installing a water softener or descaler unit can significantly reduce the mineral content that causes limescale to form.
Regular maintenance of plumbing systems—such as routine flushing of pipes and descaling treatments—also helps to prevent build-up before it becomes problematic.
For commercial and industrial settings, automated dosing systems can be used to introduce scale inhibitors into the system, protecting internal pipework and appliances.
