Above-ground pools provide fun for the whole family and can be found in different shapes and sizes. These pools are connected with PVC pipes that bring the water into the pool. As these pipes play a very important role in the plumbing system, choosing the right pipe size is crucial. Picking the wrong size can have bad consequences for your pool. In this article, we’ll cover which type of PVC pipe you should use and what is the right size for your pool. So, let’s start!

What Size PVC Pipe For An Above-Ground Pool? Usually, above-ground pools use PVC pipes that are 2” in diameter and can hold the pressure of 166 PSI. However, when replacing old pipes with new PVC pipes, they need to have the same dimensions as the original. Flexible PVC pipes that have Schedule 40 are recommended for this type of pool.

Pool plumbing system play a very important role in every above-ground pool. PVC pipes connected to the pool need to fit perfectly into the valves to carry the water into the pool. Also, you will need a special adapter to replace your old pipe with new ones. In the next section, we’ll discuss how to choose the right PVC pipe for your above-ground pool.

Types of PVC Pipes For Above-Ground Pool

Type of PVC Pipe size for above-ground pool

When you have decided to replace your old PVC pipes with new ones, you first need to decide on the pipe type you want. There are several models on the market. Therefore, choosing the right one that fits your pool plumbing system is important. Here are the two most common types of PVC pipes:

1. Rigid PVC Pipe

This type of PVC pipe is used for plumbing a pool with a minimum Schedule of 40. This type of pipe is 2” in diameter and can hold the pressure of 166 PSI. Rigid PVC pipes are known to last longer.

2. Flexible PVC Pipe

Flexible PVC pipe is widely used in new swimming pools. It has the same outside diameter as the rigid model (Schedule 40). The advantages of this model are reduced labor. However, the disadvantage is the high cost. Flexible PVC pipes are used more in above-ground pools than rigid models.

PVC pipes can be found in schedules 40 and 80. PVC pipe that has schedule 80 has much thicker walls compared to schedule 40 model. However, when it comes to above-ground pools, they don’t need to have scheduled 80 PVC pipes.

If you have a PVC pipe with schedule 40 and 2” in diameter, it can operate at 166 PSI. By using these parameters, you can notice that you have a very high safety margin. You will waste money if you choose a PVC pipe with schedule 80 for your pool.

Benefits Of Flexible PVC Pipe For Above-Ground Pool

If you are looking for a flexible PVC pipe, you’ll find that they have several advantages compared to other models. Many above-ground pools use flexible PVC pipes. Here’s why:

  • Easier Installation. The first advantage of these PVC pipes is their ease of installation. When using rigid PVC pipes, you must measure your pipe precisely. However, when using a flexible PVC pipe, you have more room for adjustment.
  • Greater Resistance. Flexible PVC pipes have better resistance to impacts and bumps, unlike rigid pipes, which are very sensitive to impacts.
  • Less Strain on Pipes. Rigid PVC pipes are more exposed to pressure as the pool is used, and vibrations and stress of the pipes occur, which can lead to cracks. However, flexible PVC pipes don’t have these problems.

Finally, flexible PVC pipes are a much better solution than rigid PVC pipes for many reasons. Another advantage is that they require less maintenance. The only downside is their price. They cost more than rigid pipes.

How To Choose The Right PVC Pipe Size?

Choosing the right PVC pipe size

Choosing the right PVC pipe size for your above-ground pool is highly recommended. If you choose a PVC pipe that has a larger diameter, you will not improve the efficiency of your pool. That’s because the pool has a filter system that has a limit to which it can pump water, and a larger pipe will not increase the flow of water.

PVC pipes with a 2” in diameter are recommended when replacing your old ones with new ones. The filter and the above-ground pool pump can usually deliver around 50 gallons of water every minute.

Because of that, using a PVC pipe that is larger than 2″ in diameter makes no sense. You will not get more flow if you opt for a bigger pipe. In order to get a higher flow rate, it is necessary to change the size of the pump. However, in most cases, it makes no sense to buy a new pool pump because it’s too expensive.

How To Find PVC Pipe Connections?

After choosing a suitable PVC pipe for your above-ground pool, you need to connect it to the pump and the pool. As more and more manufacturers use flexible pipes, they also include proper water-tight connections in their packages for these pipes.

Finding the connection that fits the adapters can sometimes be challenging. That’s because most of the fittings do not match with above-ground pool fittings and pumps that the pool has. It’s best to call your manufacturer and ask him about the best adapter fittings for your pool.

Do PVC Pipe Needs Paint Protection?

PVC pipe doesn’t need paint protection. These pipes are not sensitive and can withstand UV light without losing properties such as strength. Although high exposure to the sun will change the pipe’s appearance a little, it will not weaken the quality of the pipe itself.

For example, if you have a normal white PVC pipe, it may turn brown or dark after some time. You don’t have to worry about it because it’s normal. However, keep in mind that after some time, pipes become brittle, and they are easily prone to damage if you don’t maintain them properly.

Final Thoughts

Owning an above-ground pool is a great investment, especially if you have a large, spacious garden. The maintenance of such a pool does not require too much care. But after some time, replacing some parts of the pool, such as PVC pipes, is necessary. Choosing the right pipe size is important. Flexible PVC pipe is what we recommend for this type of pool. Most above-ground pools are 2” in diameter and can handle the pressure of 166 PSI. I hope this article has helped you, and for any additional questions, feel free to comment below.
