Steel and plastic are both viable materials for piping, but copper remains one of the most popular options for a variety of reasons. There are numerous advantages to choosing copper, but these have to be weighed up next to its potential issues.
Humans first discovered the usefulness of copper during the Neolithic Period, around 10,000 years ago. They made knives, hammers, and utensils as well as jewellery and decorative items. Today copper’s primary uses are in electrical wiring, plumbing, roofing, and industrial machinery.

Advantages of copper

Builders like copper because it is lightweight and flexible, making installation relatively simple.

Once in place, copper can last for 25 years or more, in part because it is less prone to rust and corrosion than steel.

Copper also has antimicrobial properties that improve its safety for humans, especially when used in pipes that transport water for drinking and cleaning.

Disadvantages

Of course, no material is perfect. You need the best quality copper if you want it to last.

Copper will still be vulnerable to damage if the water pressure is too high, or if the water’s chemical composition is too acidic.

Acidity in water can lead to corrosion and leaks, as well as an unpleasant taste.

Spotting problems

If you use copper pipes and copper pipe connectors, such as those available from specialists such as Watkins and Powis, you need to be aware of potential signs of leakage, including ceiling stains, damp carpets or sudden changes in water pressure. Blue-green stains in your bath or shower could be an early indicator of corrosion.

You can reduce the corrosion risk by switching off and draining your water while away. It also helps to be aware if your neighbours have problems, as they likely have a similar piping system, and therefore face similar issues to you.

Copper may be strong, flexible, and easy to use, with minimal risk of corrosion. However, you still need to be alert to potential leaks and damage to your copper pipes if you want them to continue to work effectively, without damaging your property.
