Swimming Pool Plumbing: A Comprehensive Guide

Pool plumbing systems are an important part of the overall operation of your pool. They need to be properly installed, maintained and repaired. This article will provide you with a comprehensive guide on swimming pool plumbing so that you can have a better understanding of how they work.

How pool plumbing systems work

The pool plumbing system is a complex network of pipes that carry water from the tank and through each component, from the filter to your spa. The purpose of each component is different and should be considered when choosing a new one for your swimming pool.

The most important thing you need to know about swimming pool plumbing systems is how they work together. The process starts with filling up an empty pool with water so that it can heat up. It ends when all of its minerals settle out in an even distribution (or “settling”). This process can take anywhere from 24 hours to several days, depending on where you live, but there are ways around this issue if necessary.

In order for this process to happen not only efficiently but also safely, many different types of equipment come together within these systems.

Plumbing the main drains

The main drain is a pipe that runs from the pool to the street. It’s usually located at a low point in the pool and should be sized based on your capacity. But it’s also important to make sure that this drain is located at least 1.5m away from any structures or equipment in your yard.

If you’re not sure where this pipe is located on your property, talk to a professional. It may be easier than digging up your lawn.

Plumbing the skimmer

The skimmer is the last thing you want to mess with when it comes to pool plumbing. If your skimmer isn’t working properly, then your pool will not be as clear as it should be. So, how do you know if a skimmer needs fixing? There are two main criteria: location and drain placement. Let’s take a look at each of these points in turn:

Location – The first thing that should always come into consideration is whether or not there are obstacles, such as rocks or other debris, in the way. If so, then try finding somewhere else near where those objects can be removed before moving forward with this step!

Drain Placement – Your second step involves deciding on exactly where each drain line connects back up into itself. This is the point before it enters one of several possible outlets at either end of the said line. You may also choose just one particular outlet since both options work well. However, this will depend on the type of plumbing that has already been installed.

Plumbing the returns

Plumbing the returns is an important step in plumbing your pool. Return pipes are used to distribute water from your pump, skimmer and main drain to the deep end of your swimming pool.

Return pipes are usually located at the deep end of a swimming pool, where they connect directly with drain orifices (also known as weep holes). The length of these return pipes depends on what type of return you have:

  • Foam-layed or tile drains have short lengths that run along either side of their openings. These types can be connected directly to existing plumbing systems without requiring any additional piping work.
  • PVC pipe installations will require more effort. This is because you or your perth pool installer will need to install new sections of pipe within existing walls before connecting them together again at each endpoint.

Plumbing a pool heater

If you have a pool heater, then the return side of your plumbing will be a little different. We will plumb your return side like this:

  • Run the pipe from your filter to where it connects with either your heat pump or regular non-heated water source. This could be an outdoor faucet or swimming pool pump.
  • From there, run that same line back down through whatever opening it came out of and then into your port labelled “Return”. This is where it splits off into two separate paths. One goes back into the pool itself, and another path leads over to somewhere else outside if needed.

Plumbing other pool equipment

Swimming pool equipment is another important part of the swimming pool plumbing. Pool filters, cleaners and heaters are some of these other pool equipment.

Pool filters help maintain water quality by removing debris from your pool water. Pool cleaners can be used to clean up debris in your filter or even remove stains that may have been left behind by algae or bacteria growth on its surface. Heaters help keep your water at an ideal temperature so you won’t get any skin irritation from cold or hot weather conditions. It is crucial that you get the plumbing of these types of equipment done right. Otherwise, these types of equipment won’t work and might even harm your fibreglass pool.

Pressure testing your pool plumbing

When you’re looking to pressure test your pool plumbing, there are a few things you should know. First, it’s important to note that there are different types of pumps and filters. Some can be replaced easily, and others may require more work. If the pump is working but has been damaged from corrosion or improper installation, then replacing it will be necessary before moving forward with other testing steps.

Second, keep in mind that proper maintenance is key when it comes time for pressure testing. If there’s not enough water flowing through your system, then this could cause issues with how well everything works together as well.

How deep should pool plumbing pipes be buried?

The depth of the pipe depends on the type of soil. For example, if you have an artificial turf surface, then it is recommended that you bury your pipes at least 1.5 meters below the surface. If you have a concrete pool deck or simply flat ground, then it is best to bury them at least 2 meters below ground level.


We hope this article has been helpful to you in learning more about pool plumbing and all of its components. The important thing is to understand how each part works. This way, when there is an emergency or problem with your pool, you can stay safe and know what needs fixing.
