Where Does Pool Leak Water Go?

If your pool is leaking, then you may be wondering where the water ends up after it’s left the pool.

Pool leak water can seep through the grass and surrounding areas, making your soil or grass soggy. Your deck and patio may sink or lift.

Equipment-related leaks can lead to dripping and spraying of water. Ponding in the area may occur as well.

The good news is there’s a lot of ways for you to check (and address your leaks.) You’ll find all of them below.

What Happens When a Pool Leaks?

When pool water leaks, it can seep through and make everything around it saturated with water. Not only will this make the surrounding soil damp and spongy, but it can also damage pool decks, patios, and outdoor landscaping. 

Leaks caused by damaged equipment, on top of all this,  can result in sprays and drips. You may see this as water stains on the concrete pad. 

Water may pool around fixtures or devices as well. 

Apart from these obvious signs, you may also find it harder to balance your pool’s pH. Since the pool loses water, the chemistry gets diluted. 

As a result, you may need to add more chlorine and CYA. You may even have to run your salt generators longer to make chlorine. 

Given these changes, a leaky pool often needs more frequent cleaning or vacuuming. Unlock the secrets to effortlessly repairing a leaky pool skimmer – click here for expert solutions!

Why Does My Pool Lose Water Overnight?

There are several reasons why your pool is losing water faster:

Pool Cracks

Some cracks are easily seen, but some are very small. Be aware: they tend to grow out over time – and once they’re finally detected, a lot of water has been lost already.

If you think cracks are responsible for your pool leaks, you can confirm your hunch with a dye test.

Where Pool Leak Water Goes

The steps are as follows: 

  1. Clean and vacuum the pool to make it easier for you to find leaks.
  2. Make sure that the water level is above the skimmer. 
  3. Turn off the pool filter to keep it calm. 
  4. Apply the dye on the suspected cracked areas. 
  5. If there is a leak, the coloring will be ‘sucked’ into the crack.

Dropping water levels can be caused by leaks and evaporation, making it difficult to conclude that a crack is the source of the problem. #SealingPoolCracks #NelsonPoolCompany #BestPoolRepairInSarasotaFL #PoolMaintenancehttps://t.co/gtveTDK61W pic.twitter.com/IMZMpIgL0m

You can also perform a bucket test to see if you have a leak or plain-old evaporation. To do this, you need to:

  1. Place a bucket of water beside the pool.
  2. Mark the bucket and pool water levels. 
  3. Wait for 24 hours before checking the levels of both.

If the pool has lost more water than the bucket, it’s a sign that there’s a leak in your pool. 

Defective Equipment

Leaks don’t merely occur in the pool itself. They can seep through the equipment pad, heater, pump, and valves. This leak usually happens when you turn any of these devices on.

Pool Leak Effects

Leaks From Pool Lights 

Just like the equipment above, your pool’s lights may cause some leakage as well. This is especially the case if they’re not sealed tightly.

You can check for pool light leaks through a dye test, like spotting for cracks.

Vinyl Pool Leaks

These pools have parts where leaks are more likely to occur. This means you’ll need to check the following:


While liners should last 8-20 years, they’re not safe from rips and tears. This often happens when your pet chews the liner. Another reason could be the presence of sharp-edged materials in the pool. 

Pool Pump 

There are two sides to a vinyl pool pump, and you need to check each one of them:

  • Pressure side. Signs of leaks on this part include murky water, bubbles, or a floating skimmer basket. A non-working pump – or a need to vacuum more often – are also indicators.
  • Suction side. Signs include leaks, drips, or sprays of water. Pooling around the pump and damage to the deck may occur as well.

Filtration System Issues

Your pool’s filtration system keeps the water clean by removing dirt and debris. If it has leaks anywhere in its structure, it can also lead to water seepage. 

The foremost sign of a leak is bubbling. Note that bubbling is normal when you first turn on your filter. If it persists, it’s a sign of a leakage in the system.  

Skimmer Leaks

A part of the system that’s prone to leaks is the skimmer. Since the design varies according to each pool, here’s how to check them accordingly: 

  • Concrete Pool

If you have a concrete pool, you should check the skimmer whenever you remove it. Make sure to inspect the mouth for missing pieces. If there are any, then your pool may be having some skimmer problems. 

It’s also good to check the cement seal between the pool wall and the skimmer. Again, you can check this through a dye test. Note that you need to squirt the dye directly on the main drain.

  • Vinyl Pool

Vinyl pool skimmers can leak if they are not sealed well to the wall. 

As with a concrete pool, you can conduct a dye test to check your vinyl pool skimmer for leakage. If this is the case, you should tighten all the skimmer screws with a Phillips screwdriver. 

Problems in Underground Plumbing

Your pool’s underground plumbing can be damaged by ground movement or corrosion. In worst cases, these can even lead to a punctured pool floor. 

If you think that plumbing is the culprit, you can easily confirm it. 

First, you need to shut off the pool pump and plug the pool lines. If there are no leaks after doing these, then it’s safe to say that there’s an issue with your plumbing.

However, if leaks continue even when the pump is off, you may need to call the Nelson Pool Company. They may have to perform a plumbing pressure test to detect and repair the pipe leaks.

How Serious Is a Pool Leak?

Well, pool leaks are pretty severe. For one, they can lead to a sinkhole since they can make the surrounding area soggy. The water can leak into the ground foundations, which could collapse into a sinkhole in the long run.

Then there’s the issue of high water bills. 

You may think that losing 2-4 inches of water a week is typical and caused by evaporation. This leads your automatic refiller to add water to your pool more often. Of course, this can translate into increased water bills in the long run. Click here to see how Nelson Company refills your pool and can help you.
