American Pools knows that quality pool plumbing is essential to providing you, your family, and your guests with a pleasant and healthy swimming experience. Proper plumbing ensures the integrity of water flow to minimize water loss control water costs resulting from leaks. Well-maintained pool plumbing is crucial to the efficient operation of your pump and filtration systems that help maintain a superb aquatic experience you expect.


Regular maintenance and inspection of your pool’s plumbing system can help ensure optimal function. As a general rule, if you see water somewhere other than in the pool, something is wrong! Unfortunately, sometimes the pool plumbing that serves your system can become damaged in several ways – whether due to environmental wear-and-tear, accidental damage, or perhaps negligence of a prior owner. The good news is that American Pools can, in many cases, repair many of these types of issues for as little as $100!

Common Pool Plumbing Issues

Pool pump inlet and discharge plumbing leaks

If your pool pump isn’t receiving a full prime of water, it is likely due to a suction leak. These often occur on the inlet or discharge plumbing joints between your pump and the rest of your system. Bad pump valves or O-rings are often worn and require replacement. Our technicians can examine your system to identify these types of simple issues and can generally make these repairs on-the-spot. In other cases, there may be issues with the plumbing adapter itself. These are also relatively easy repairs that generally require only about an hour to complete.

Leaking filter backwash valves

Aging plumbing in the area around your pump and filter equipment are particularly prone to experiencing leaks due to wear-and-tear from the normal up-and-down movement. Repairs are often as simple as replacing O-rings, though other issues can occur with the surrounding plumbing because of exposure to the sun – which is particularly harsh to PVC pipe.

Black or dark-colored pipe which more readily absorbs the sunlight is particularly problematic. Whatever color pipe is used, if your setup places the pump and filter equipment in direct sunlight it is highly recommended that a bolted-down ground shade be placed over the pipes of your pool’s exposed plumbing near the pump and filter equipment to help prevent warping and degrading of these vital parts of your system.

Broken ball valves

In spite of all the joy that nearly year-round sunshine brings to Phoenix and the “Valley of the Sun,” you’re probably discovering that it’s not so friendly to your favorite backyard escape!

Ball valves, which are found throughout most pool plumbing systems to control the flow of water to and from nearly every part, are particularly susceptible to breaking – sometimes right in your hand as you operate them - because they’ve degraded from the stress of the sunlight and heat. Whether you are unable to control water through your pump and filter system, or turn your water features on and off at will, this can be a bit of a nuisance. The good news is that, depending on the location of the valve, repairs or replacements can typically take between a half-hour to an hour-and-a-half.

Underground Pool Plumbing Leaks

Thankfully, this class of leaks is relatively rare on a well-constructed pool. Underground leaks on the suction side of your pool plumbing system cause the system to suck in air, and are often found after simpler interventions – such as replacing O-rings – fail to correct an issue. When they do occur, the majority of underground leaks are typically found in one of three locations:


Near the pool pump

The simplest underground leak to fix, these generally occur near the plumbing joint where the line “elbows” up toward the ground surface at the pump.

The point of origin

While in many parts of the country these can be easier to spot due to large wet spots on the ground, in Arizona the ground is particularly dry and my absorb the water before it reaches the surface. You can sometimes use satellite photos of a property to identify these leaks.

Over time, plastic skimmers crack, and it is very common to find a crack in either the glue fitting or the skimmer itself cracks.

Some pools have a dedicated vacuum port, which is another common source of leaks due to mechanical damage from the strain of attaching, detaching, or using the vacuum line.

Main drain line cracks can result in significant leaks – the type that you’ll notice when they cause your water bill to go through the roof! A full repair of a main drain crack can be quite expensive unless you are having your pool replastered at the same time because of the need to tunnel down to that part of your pool. There are usually short-term alternatives that can help mitigate the issue until it’s time to replaster your pool. American Pools can help identify whether inserting a plug into the main drain line can help to address these issues. These plugs can typically remain in place for between three and five years prior to requiring replacement.

Near larger vegetation adjacent to the pool

Roots of many types of vegetation, particularly trees, can be an anticipated cause of leaks. Because strong roots can actually lift the foundation of a home, it isn’t surprising that when they encounter the PVC pipe used for your pool plumbing there is simply no match.
