Plastic pipes are preferred most because they are long-lasting and their life span is up to 50 to 60 years.

If you want to compare the cost or price of both pipes, then pex pipes are more costly than PVC pipes. The PVC pipes are available at less prices in the market compared to the others.

Now point to note is that there is less labor cost required to install the pex pipes, so there is not such a difference in cost factor on both of them.


As it is mentioned above, pex pipes are more flexible, so they are very easy to install on every side of the building. The plumber can easily bend them to turn the direction of the pipes.

While PVC pipes are not flexible, therefore, they are difficult to install, which eventually increases the labor cost.

Affinity with the metal pipes

If you want to join the connection of a plastic pipe to a metal pipe, then the pex pipe is better than the PVC pipe because it will not wear out after joining with the metal pipe.


If you are installing the pex pipes, then it will finish the issue of noise during the plumbing because of the water hammer. Pvc pipes generate unusual sounds and make noise of banging sound in plumbing.


The durability and life span of the PVC piping are more than the pex pipes. The normal longevity of the PVC pipe is a minimum of 70 years, while the pex pipes have 50 years.

Water leakage

Pvc pipes are rigid and not flexible, so, therefore, connections of two pipes will need an elbow. There will be a chance of leakage of water from the joints.

In pex pipes, fewer elbows are installed, so they do not leak the water most of the time.

Outdoor security

You can use the PVC pipes in outdoor conditions even if you can install them above the ground level. On the hand, pex pipes cannot bear the sunlight in outdoor conditions.

This lack of exposure to sunlight limits their usage by homeowners.


The final thought of all this information is that both plastic pipes are equally good to install in the plumbing of the home. Although they have some pros and cons, you can choose any of these two pipes.

Generally, pex pipes are used in indoor conditions, and PVC is preferred on outdoor surfaces for drainage of water.
