Are copper pipes safe for humans?

Although metals such as lead have been banned for their toxicity, leaching harmful substances into water, not all metals pose the same risks to humans. Copper pipes have remained a popular piping material for years, so let’s look at whether their safety justifies their widespread usage.

Why copper?

Copper serves as an excellent material for plumbing due to its lightweight yet strong nature. Copper pipes are stronger than PVC pipes and don’t possess the drawbacks of other metal pipes (lead).
The material is durable and corrosion-resistant, allowing it to withstand years of consistent usage without decaying. Copper pipes are not invincible, of course, but the metal is easier to work with and install thanks to its lightweight yet malleable nature, which means speedy replacement.

Copper pipes and copper pipe fittings are available from pipeline merchants such as https://watkinspowis.co.uk/products/copper-pipe-fittings-and-press-systems.

Are copper pipes safe?

As previously mentioned, metals such as lead can leach harmful substances into drinking water, causing lead poisoning after prolonged exposure and eventually resulting in a complete ban on the metal. Copper also leaches into the water, with small traces of copper being carried along in the water you use; however, unlike lead, copper is beneficial in small doses. Our bodies use copper to keep our heart, blood, and muscles healthy, with the trace amount in the water not nearly significant enough to cause you any harm.

The only time copper may be harmful is if too much is consumed, which is more likely for infants or pregnant women. Those with Wilson’s disease or who have had a liver transplant should also avoid excess copper consumption.

To reduce the risk of ingesting too much copper, you can use water filters, allow cold water to run through the pipes for 30 seconds (to clear out any traces), and avoid using copper cookware. For the average person, the chance of overconsumption is very low, so don’t get too worked up about the stats.

Copper pipes are also safe for the environment, being a natural resource fit for recycling, reusing, and repurposing without releasing any harmful toxins.
