An Expert Guide to Choosing the Right Piping Material for Your Plumbing Application

plumbing system being repairedPlumbing is an essential part of any construction. The choice of your plumbing material is one of the biggest you will make. There are many pipe material options available in the market.

The perfect material option for your plumbing depends on the application and installation location. Industry expert REHAU South East Asia will say the same. The type of plumbing system will also influence your decision. Here are the typical pipe materials used nowadays.

Polyvinyl Chloride (PVC)

This option works for most settings because it is rust-resistant, durable, and withstands high pressure. It is also inexpensive and requires no metalwork and welding. The main limitation of PVC pipes is that you can't use them in hot water applications.

They are also best suited for underground and indoor use as UV rays cause them to deteriorate. This makes them ideal for the bathtub, toilet, sinks and high-pressure indoor lines.


Copper is the gold standard for most plumbing applications. It is long-lasting, corrosion-resistant and tolerates heat very well. It is also the safest for drinking water. It is, however, an expensive option. You can use it for refrigerant HVAC, underground service, as well as hot and cold supply lines.

Crosslinked Polyethylene (PEX)

These are the most modern pipe materials. PEX is flexible and is hence able to be snaked around corners. It requires no gluing and holds up well in freezing conditions since it can expand and contract.

PEX pipes are the best options for retrofitting older homes, snaking through walls and low ventilation areas where glue poses health concerns.

Chlorinated PVC (CPVC) is another popular plumbing material option. It is durable, can be used for hot water, is fire-resistant and is safe for carrying drinking water.

It is also well-insulated hence loses minimal energy in cold and hot applications. CPVC pipes will, however, split in freezing conditions. Stainless steel, brass, and cast iron are also common material options for plumbing.
