Pool Leak Repairs Brisbane - FAQ

How Can I Tell If My Pool Is Leaking?

Pool Evaporation Calculator

The most obvious sign that a pool is leaking involves more rapid water loss than normal. To work out normal water loss for your pool, check out our pool evaporation calculator.

Bucket Test

The bucket test is a great way of finding out the cause of your leak. It lets you test evaporation or a leak. If your pool loses water faster than the bucket, you likely have a leak.

Check For Nearby Water

Additionally, you may begin to see damage on your pool’s surface near where the leak is located, such as tile damage and delamination.

One sign of a more serious water leak is having a muddy or soggy yard around the pool. This can lead to damage of concrete or tile surfaces around your pool, such as foundation settling. This may require a pool tiling specialist in Brisbane to restore it back to its original condition.

Occasionally, leaks can lead to excessive algae growth. This occurs when soil-matter leaks back into your swimming pool through surface leaks, which more commonly occurs during times of wet weather.

Soil-polluted water is naturally high in phosphates, an organic compound that acts as a natural food source for algae colonies.

Leaking Pool Needing Repair

Where Is The Most Common Place For A Pool To Leak Water?

The most common places for a Brisbane pool leak are near seams in the construction of the pool. This can vary slightly by pool type, but most often occurs in corners, near steps, skimmer boxes, and by the waterline.

You may also find leaks near drains or pump inlets and outflow jets. Typically, leaks occur more often in these places because the joining material between the structural components of your pool is in poor condition.

This joining material, sometimes grout or caulking, may have not been applied well, or it could simply be too old to perform its function.

Can You Fix A Leaking Pool Without Draining?

It is difficult to truly fix a pool leak without draining your pool’s water level to a height just below the leak. However, there are some stopgap options that you can apply with water in the pool.

Lo-Chlor Leak Sealer is a good example of this. Most users tend to find that this slows down a leak rather than stops it, so a leak detection expert will still be needed to fully diagnose and fix the leak.

What Happens If You Don't Fix Leaking Water In Swimming Pools?

Water leaks that are left unfixed can cause catastrophic damage to your entire pool, and may even affect your house foundations if they are close to the pool.

The most serious types of damage associated with this are cracks in the outer shell of the pool and irreversible damage to the foundation. In most cases, pools will have to be entirely replaced if this type of damage occurs.

Smaller scale damage will happen before your pool gets to this point.

This mainly includes damage to your pool’s equipment, which may begin sucking air (if the water level drops below the skimmer box or return jets), and delamination of the pool surface near where the leak is located.

This kind of damage is not as catastrophic as the types we mentioned above, but it can still be more costly than attending to a leak as soon as possible.

Keep in mind that if the leak is caused by plant roots growing into and damaging your pool, the leak is likely to get worse and worse over time. It's better to take action while the leak is still quite small.

It's also a reminder that it's a good idea to consult a landscaper before planting trees around your pool, as they can advise which types of plants are most suitable (often those with the most contained root systems).

How Long Does Swimming Pool Leak Detection Take?

Simple Pool Leaks

Leak detection services can typically be performed in one day when using competent service providers. This can occasionally take up to 48 hours, particularly if you have a slow leak, but should not exceed this period.

The amount of time it will take to repair your pool’s leak depends on a few factors. These include the type of lining, the size of the leak, and any related damage that the leak has caused.

Severe Pool Leaks

More severe leaks that have caused structural damage to your pool may take up to three weeks to remedy (including draining and resurfacing), while leaks that are caught early-on can sometimes be repaired in one day's work.
