Types of Piping Used During Inground Pool Installation / Construction

Inground pools are a great addition to any home. Currently, there are millions of residential pools in America alone and more being added every year. The right piping is essential for the successful installation and construction of these pools. If you are considering an inground pool installation, it is natural to have questions about the correct materials to use for this process. Below, we have provided information to help you find the right pipe for pools and the fittings that accompany them.

Pipe for Pools

There are many different piping options for residential inground pools. There are pros and cons for each type. Knowing the difference between each type of pipe will help you to determine the best choice for your inground pool installation.


PVC pipe is found in many inground pools. Being the most commonly used pipe for this job, PVC is well trusted. However, there is more than one type of PVC pipe to consider. PVC piping can be either rigid or flexible, and each serves a different purpose.pipe for pools

Rigid PVC pipe is highly durable. This type of pipe is thought of as the best pick for standard residential swimming pool plumbing. It comes in both schedule 40 and schedule 80 options. Typically, schedule 40 is thought of as durable enough to support a pool system. Schedule 80 is slightly more expensive and can handle more pressure than schedule 40.

Flexible PVC pipe is tube-like piping that is made to bend and move. This type of PVC pipe has the advantage of not needing fittings. It is also made to endure freezing. It does have some major downsides, though. The flexibility of the pipe can lead to leaks and cracks. It is also less chemically resistant than its rigid counterpart and is susceptible to insect attacks.

Black Polyethylene

This type pf pipe is frequently found in older inground pools. It is a flexible option that mirrors the flexible PVC pipe. However, one of its main advantages is its chemical resistance. It does not attract insects which is another big benefit. Though black polyethylene pipes do have many advantages, one of their biggest disadvantages is that they are leak prone.


Before PVC, this was the most popular type of pool piping. It is much less commonly used now because of its tendency to corrode over time. Copper pipes require much more skill than the other types of piping listed here. It is easy to make mistakes when installing this pipe so it is important to have the knowledge required before installing. This type is highly earthquake resistant though so if you are in an earthquake prone area, copper pipes may be worth exploring.


This type of pipe is used best for hot water applications, such as hot tubs. They have higher heat resistance than PVC and if you are planning on a heated pool, this might be a good option for you. CPVC pipe is one of the most expensive options, so the cost may not be worth it if you do not need to heat your pool.

Fittings are just as important as the piping when it comes to pool installation. They ensure the successful flow of your inground pool piping system. The type of fitting you need will be determined by the type of pipe you choose. Some piping options do not even require fittings so definitely make sure you need them before you go to the trouble of buying them. If you buy a wrong or incompatible fitting it could lead to leaks or breaks. Sealants are also an important factor to consider.

Finding the right pipe for pools is not as difficult as it may seem. Even though there are many options, it is easy to determine which type best meets your needs. If you have questions or concerns about inground pool piping, do not hesitate to contact a professional.
