Pool Leak Detection Phoenix

When you work with Leak Science as your pool leak detection service, you’ll save lots of headaches and money in the long run. The City of Chandler has cited that an estimated 30% of all pools in the valley leak and waste water unnecessarily. That is a significant amount of wasted water and money. What’s scary about pool leaks is that more often than not, people simply do not realize they have a leak until significant damage appears.

A swimming pool requires a lot of upkeep, and nobody finds it enjoyable to work hard just to have it all drained away. A single pool leak can drastically raise your water costs and reduce the lifespan of your pool. Although it may be challenging to locate a pool leak, doing nothing might have terrible consequences. The most typical indication of a leak is too much water around the pool’s perimeter, which might result in muddy patches or even puddles. It might be risky and easy perilous to navigate this muck and water. When compared to the potential risks of a persistent pool leak, hiring a professional is always a wise decision.

There are many indicators that your swimming pool and or related water features may be leaking. You may have a leak if:

  • Your water bill suddenly increases
  • If any of your hardscapes around the pool (non-living element of landscaping such as a brick patio or a stone wall)
  • If you have cracks in the surface of your pool or spa
  • If you are adding a significant amount of water to your pool daily
  • Your pump is losing prime


Before calling a pool repairman if you think your pool is leaking, there are a few things you should look at. Initially attempting to handle the issue on your own may be beneficial financially because pool repair service calls are sure to cost you some of your hard-earned bucks. Without further ado, the following are the items you should evaluate before consulting pool repair professionals:

Does it leak when the machinery is running? 

If this occurs, the filter pump may be to blame for a pressure-side return leak. If there is water running continually, check the waste line or backwash. Then, examine downhill from your pool for weepers that are leaking underground. 

Does it just leak when the machinery is turned off? 

This can be a sign of a suction side leak or a leak in the pipes carrying pool water. This is most likely the issue if there is air in the filter tank, air in the pump basket, or air bubbling out of the return lines. If you want to be certain, you can measure and mark the water levels using a pencil or a tape measure.

Does it constantly leak? 

Anything from plumbing leaks to pool fractures might be the cause of persistent pool leaks. Look closely inside the skimmers and at the tile line to see whether the issue is with your pool. Turn off the pump and pour some test dye near any area that appears to have a crack to observe whether the dye is sucked into the fracture. Additionally, the conduits in underwater lights might lead to leakage. A pool putty may be used to quickly patch either of these issues. 

Are there any leaks in the subsurface plumbing? 

One of every pool owner’s worst fears is a leak in the subsurface plumbing since repairs are frequently time-consuming, costly, or both. By turning off the pump and blocking all the lines, you may check to see if the subterranean pipes are indeed leaking. The issue is not with the pipes if it keeps leaking. In contrast, if the leaking stops, you may check to see if it resumes by removing each plug individually. Once all other options have been ruled out, you may do a pool plumbing pressure test on the subsurface plumbing to identify the problematic pipes. 

Are the pool tiles broken or shifting?

The pool bond beam can occasionally break behind the tiles, cracking the tiles. When this occurs, water may flow into the tiles from the top of the pool wall through fractures in the wall. The pool tile fractures may be quickly and simply repaired by applying a high-quality sealer. 

Are the surface fissures dripping? 

Large surface fissures in concrete pools often lead to significant leaks. A dye test can be used to determine if it leaks. Use pool putty, plaster mixture, or silicone to fill and seal tiny gaps if it is really dripping. You may execute a two-stage repair for bigger cracks using an injected sealant.

How to determine your pool has a leak in 3 easy steps

It’s normal for your pool to lose some water to evaporation, some to splash out, and some to backwash your filter. However, if you’re routinely needing to add more than 2-4 inches of water to your pool per week, you may have a leak. Here’s an easy way to determine if you have a leak:

You will need a 5-gallon bucket and a large black marker.

1) Place the empty 5-gallon bucket in the water on the second step of your pool. Fill the bucket with water to match your pool’s water level. Use the marker to mark the water level inside the bucket.

2) Turn off any auto-refill device you may have as well as your recirculating pump.

3) After 24 hours have passed, check to see if the pool water level and the water inside the bucket remain even. If the water remains even, your pool is losing water due to evaporation.

However, if the pool water is lower than the water inside your bucket, you may have a leak. Repeat these 3 steps over the next 24 hours to get a more accurate judgment as to if your pool has a leak.

Areas in Your Swimming Pool Prone To Leaks

  • PLUMBING: Swimming pool plumbing systems are often the source of the leak for numerous reasons including, but not limited to, the pipe material used, the original installation quality, the age of the pipes, the plumbing configuration and/or soil conditions.
  • SKIMMERS: For an inground pool, skimmers are the little buckets in the side of your pool. They hold baskets, which keep debris from making its way into your filter. If you have an above-ground pool, you likely have the kind that floats around in the water doing the same thing. Cracks in the skimmer or in the pipe connected to the bottom of the skimmer are very common. The most common cause of cracks in the skimmer is the material used, the age of your skimmer, and settling.
  • RETURNS: Leaks in the returns are also very common and may be due to a gasket, a leak in the pipe, or in the fitting itself. Returns are for your pool’s circulation.
  • POOL LIGHT: Leaks found in or around the pool light are most commonly either in the conduit line that the light cord is run through, or in the plaster and gunite surrounding the light.
  • CRACKS IN THE POOL SURFACE: Many are simply cosmetic in nature, but often they lead to a more serious problem. Cracks can develop in the concrete that lies beneath the pool’s finished surface due to settling, ground shifting, and erosion or as a result of being drained and exposed to the elements for too long a period of time.  All cracks in a swimming pool surface should be checked out thoroughly by a trained professional.


What Happens if You Ignore a Pool Leak?

As water escapes your pool, it can start to accumulate in areas where it shouldn’t be. Water traveling through the ground around your pool leaves your pool to become unsupported, and structural fails begin to happen. Underground leaks that are left for an extended period of time will almost always cause problems for the pool structure. No pool is built to have an active leak and having one compromises the efficiency of the pool in the short term, combined with the longevity of the installation in the long term.

In addition to losing water, a leak in your pool may let in soil and other debris. This makes it very difficult to keep the pool clean and maintain the pH balance between acid and alkaline levels. This will then lead to the growth of algae and moss. Your filter system will never rest, raising your energy cost. The lawn or garden area around your pool may be saturated with chlorinated water that can harm plants and can even extend into a neighbor’s yard.
