Cast Iron Sewer Pipe Descaling

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.
