What is my Poly-B being replaced with? 

At Great White Mechanical, we replace your Poly-B with a pipe called PEX-b. PEX-b tubing is a type of cross linked polyethlene (plastic) PEX pipe which has become a very common option in North America for plumbing and heating applications. 

PEX-B is known for being: 

• Cost efficient

• Easy to install due to it's sturdy, yet flexible structure and compatibility to many fittings (better installs = less problems)

• Durable with a higher resistance to corrosion and oxidation. It's long lifespan has contributed to some manufactures offering warranties for 25 years or more. 

• Safe for drinking water

• Able to withstand high temperature and pressure fluctuations 

PEX-b's reliable long lifespan, simplistic install capability, and affordable material makes it a cost-effective option now and in the future!

Isn't copper better than PEX-b? 

Copper is known for it's longevity as it's highly resistent to temperature changes, pressure, corrosion, and degradation over time, but there are many reasons why PEX-b is the better option. 

Cost

PEX-b piping typically costs $1.50 to $3/foot for material and labour where copper can cost anywhere from $3 to $10/foot. 

Ease of Installation

PEX-b is easy to bend and cut requiring fewer fittings and a quicker and easier installation. 

Durability

Both PEX-b and copper are highly resistant to corrosion and can withstand high pressures and temperatures. Copper does have a longer lifespan of 50-70 years compared to PEX-b which can last anywhere from 25-50 years. 

In freezing temperatures though, PEX-b's flexibility allows it to expand when water freezers, preventing bursts. Copper pipes can crack and burst in cold climates. 

Noise

PEX-b is less prone to noise and water hammer compared to copper pipes. 

Efficiency

PEX-b has a lower thermal conductivity than copper, meaning it can maintain water temperature more efficiently.

Water Quality

Copper pipes are less likely to leach contaminants into the water, but PEX-b pipes are water safe. 

Sustainability

Copper is easily recyclable, but PEX-b's lower material and energy requirements make it a more sustainable choice.
