PVC as well as HDPE are, without doubt, the two most well-known pipes utilized in underground construction. There is a lot of debate about which is the best one to utilize when it comes to pipe solutions for both businesses and homes. The two pipes PVC or HDPE pipes have strengths and weaknesses, and it is difficult to decide which one is better.

Here’s a comparison of the PVC pipe and HDPE that will help you determine the best pipe to meet your plumbing requirements.

What are PVC and HDPE Pipes?

PVC (Polyvinyl Chloride) and HDPE (High Density Polyethylene) fittings and pipes are widely used in water pipes. The PVC pipe and HDPE pipes share a few features that are the reason they are a popular option for a variety of uses.

Both are:

  • Made from plastic
  • Lightweight
  • Resistant to Corrosion
  • Resistant to chemical and bacterial build-up
  • Are more durable than steel pipes.

Differentialities among PVC pipe fittings and HDPE pipe connections


PVC is a long-lasting vinyl polymer, whereas HDPE is a thermoplastic polyethylene that is made by petroleum. Both pipes are durable and can withstand extreme temperatures. In comparing the failure rates for events such as weather, stress or cold, HDPE has been proved to be more durable. PVC pipes has a score of one out of 48,650 events and HDPE one in 10,000,000.

Flexible PVC pipe but is more suitable for single-time projects. 


The gasket or glue sealant employed to connect PVC pipes. HDPE pipe fittings are connected using heat melting. Thus that, although the fittings of PVC pipes are able to be joined to the water, HDPE cannot.

However, HDPE pipes are able to resist and reduce shock waves than PVC.

Thermal Performance

The continuous exposure to cold or hot conditions causes the slow expansion of pipes and fittings. HDPE pipes are four times faster than PVC pipes.


PVC is able to be installed on Open Trench and Drop Burial methods. Installation is simple and fast without relying on weather conditions and does not require any special equipment. In general PVC Pipe cost is very low.

HDPE pipes can be positioned into Open Trench, Drop Burial and Directional Bore and Horizontal Bore methods. Highly trained personnel and energy-intensive equipment are required for the installation of HDPE fittings. HDPE pipe cost could be more expensive.


PVC pipes are more durable and more rigid, which means they can be joined mechanically to valvesand fittings made of non-plastic. The main drawback is the possibility of the possibility of water leakage through these joints.

The more flexible and soft HDPE pipes have leak-proof joints to stop leakage of water.

Use in Irrigation

PVC pipes are commonly employed to water irrigation. But, more people choose HDPE pipes for irrigation systems in which digging is difficult or even impossible. For irrigation systems for golf courses, HDPE pipes are best for the job.


The most frequent use of PVC pipes is for water pipes in homes. PVC pipes are also used to serve drainage, sewers, and industrial use.

HDPE is used in more diverse ways to distribute petroleum, natural gas and other chemicals. HDPE is also used in sanitary, water and storm sewer systems.
