Copper pipes remain a popular choice, and have been used in commercial and residential properties for many decades. But what are their pros and cons, what are the different types, and how long should they really last?
Copper pipes – pros and cons
The main advantages are that they are lightweight, flexible, 100% recyclable, naturally corrosion-resistant, reliable, strong, able to withstand temperature extremes, and do not contaminate water. Additionally, they are generally regarded as being highly durable and long-lasting.
The main downsides are cost, complexity of installation, and the fact that they may not be suitable for use where the water is of high-acidity.
Connecting copper pipes
There are many occasions where copper pipes need to be joined to each other. This is where copper pipe connectors, including special fittings and press systems, have a significant role to play.
There are a number of companies in the UK who specialise in copper pipe connectors and similarly useful products. Many of these, including Watkins and Powis and others, also offer useful information and advice as well as a range of innovative products.
Copper pipes – types
There are generally three different types of copper pipes that are used in water systems nowadays. These are: M-type, L-type, and K-type. These are categorised based on the thickness of the walls.
- M-type pipes are the thinnest and, subsequently, the lightest and easiest to work with.
- L-type pipes are of medium thickness and tend to be the preferred choice for residential buildings, and some underground/outdoor applications.
- K-type pipes are the thickest, heaviest, and most expensive of the three. These tend to be found in industrial settings in applications such as waste disposal systems and HVAC systems.
So how long should copper pipes really last?
Whilst some copper pipes may need replacing after as little as 10 years, many will last much longer than this. Indeed, some K-type pipes may well last nearly 100 years. Overall, copper pipes have a longer average lifespan than PVC pipes, galvanised steel pipes, and PEX pipes.
