Copper Repiping

Copper repiping is among the most common types of metal piping. The copper has a lot of advantages which makes it a competitor against PEX and PVC. They can be utilized for outdoor and indoor plumbing. Although they are of copper, these piping systems are highly resistant to erosion.

Apart from erosion copper piping has other advantages which include;

  • It has a long lifespan

Even with its advantages, copper also has disadvantages such as; it’s difficult to install which makes it more expensive to install than other systems. Another disadvantage is, it’s prone to theft due to the high value of recycled copper. Therefore thieves are known to remove copper from businesses and in homes.

PEX Repiping

This is a highly colorful, flexible and cross-linked polyethylene, it’s also known as XLPE or PEX. The variations from PEX tubing meet the CSA Group, American Society for Testing Materials (ATSM) and NSF International standards. PEX is made by melting a high density polyethylene then extruded into a tube shape, which causes a cross-linking chemical reaction thus increasing resilience, resistance to low temperatures and increase in strength.

The following constitutes the benefits of using PEX piping system.

  • It can be coiled during shipping due to its high flexibility
  • Large quantities can be shipped as you can coil them up during shipping
  • Each coil provides a long pipe capable of being bent up to 900c or more without using an elbow joint. Therefore, you can save on money and time and reducing the risks of joint leaks
  • PEX is also immune to scales, corrosion and its resistant to freezing
  • The pipe doesn’t transfer heat nor requires welding and it can be connected in different ways

PEX piping can be connected through compression, expansion, push-fit, Stainless Steel Clamps (SSCs) and copper crimp rings.

PVC Repiping

The Polyvinyl Chloride is a more popular and modern plumbing piping. It’s an alternative to metal piping and more durable than the polybutylene. PVC repiping has the following benefits

  • The pipes do not require welding
  • The pipes are resistant to corrosion
