Copper has been used in water and irrigation systems for many years, with evidence of use going as far back as the Ancient Egyptians. However, it only really became the preferred water pipe material after World War 2.
Attributes
There are several reasons why copper is a popular choice for water pipes.
Copper is durable
Copper pipes, unlike galvanised steel ones, do not corrode. This means they are regarded as durable. Some types can last for in excess of 100 years.
Copper doesn’t contaminate water
Lead pipes stopped being used because of the potential for lead dissolving and contaminating the water supply. Lead poisoning can be very dangerous. Copper pipes are, however, corrosion-resistant.
Copper is eco-friendly
Because copper is a naturally occurring material, copper pipe production does not cause pollution, unlike synthetic plastic manufacturing. Copper is also recyclable.
Copper is lightweight yet strong
Copper is quite a light material which makes it easier to lift and align. Despite this, it is long-lasting and can withstand more than 1000 psi of pressure.
Copper is heat and fire resistant
Copper has a high thermal rating, meaning that it is fire-resistant and able to handle heat with no issues. This is evidenced by its use in hot water systems. Additionally, it does not emit toxic fumes when subject to flames or fire.
Copper is UV-resistant
As it is unaffected by UV, copper piping can be used in outdoor or exposed areas. Alternatives such as PEX can degrade over time if exposed to UV.
Joining copper pipe
Traditional joining methods such as welding and soldering are still preferred by many, but there are a number of scenarios where these flame-based methods are not feasible. For these occasions, there are a number of specialists such as watkinspowis.co.uk/products/copper-pipe-fittings-and-press-systems who offer a range of modern alternatives for connecting copper pipe.
Alternatives to copper
There are several alternatives to copper pipes when it comes to plumbing and water systems. The most commonly used ones are three types of plastic: PEX, PVC, and UPVC.
