Home Plumbing Choices: Copper vs. PEX Piping

If you are picking pipes for your home, it’s like choosing between two top football teams. Some people cheer for copper piping because it is strong and can last a very long time. It stands up to hot water and high pressure but needs care to avoid leaks and dislikes freezing weather.

Copper can also slip tiny bits into water that we shouldn’t drink.

PEX piping is more like a new, quick player on the block. It’s made of plastic that bends easily and doesn’t rust or get choked with hard stuff in the water. PEX likes the cold better – it won’t burst if things get frosty! It costs less to set up than copper and takes care of itself without fuss, lasting between 25-40 happy years.

The choice isn’t just about which one works today; it’s also about how much they cost, whether they’re good friends with nature, and if they help our homes save energy – making them warm without wasting heat or water.

Experts suggest getting advice from plumbers when deciding.

Now let’s kick off into this match between copper vs PEX pipes!

Copper Piping: An Overview

Copper piping has long been a stalwart in home plumbing systems, revered for its robustness and traditional appeal. Delve into the characteristics that make copper an enduring choice for water distribution in residences across the globe.

Comparing Copper and PEX Piping

In comparing Copper and PEX piping, we’ll delve into their respective health implications, ecological footprints, as well as their efficiency in conserving energy to help you make an informed decision for your home plumbing needs.

Health Concerns

Copper pipes can add copper particles to drinking water, leading to health risks if too much is consumed. This problem might cause copper toxicity, which can make people feel sick with symptoms like vomiting.

They also need regular checks to stop scale buildup that hurts water quality and health.

PEX piping fights bacterial growth better than copper does. This helps keep the water cleaner and safer for everyone in the house. PEX pipes also handle cold weather well without bursting, avoiding mold problems from leaks.

Plus, they resist harmful chemicals and don’t let them mix with your home’s water supply.

Environmental Impact

PEX piping stands out as a green building choice. It uses less energy to make and does not hurt natural resources much. Unlike copper, PEX is made with fewer materials from the earth.

This makes it better for our planet’s future.
