How to Keep Your Pool Free of Leaks

A pool may look perfect on the surface, but many problems start where you can’t see them.
Water leaks are one of the main silent enemies of a pool’s structure, hydraulic system and energy consumption.

Today we want to share a guide to help you keep your pool free of leaks, prevent damage and maintain its efficiency all year long.

Why leaks are a common problem in Miami

The warm and humid climate of South Florida causes materials to expand and contract, which can create microcracks in concrete, sealants or underground pipes.
Over time, these small leaks can lead to:

• Constant water loss

• Structural damage

• Increased maintenance costs

• Risk of erosion in the base or surface finish

Detecting them early and having an efficient filtration and circulation system is key to maintaining the integrity of the hydraulic system.

How to keep your pool free of leaks

The secret is prevention and consistent technical maintenance.
Below are the most effective practices recommended by specialists for residential and commercial pools.

1. Maintain a modern and clean filtration system

The filtration system is the heart of the pool.
A clogged filter or a pump with low pressure can create hydraulic imbalances, increasing pressure in certain pipes and contributing to leaks.

Recommendations:

• Clean the filter as often as the manufacturer indicates.

• Make sure valves and connections are properly sealed.

• Check the pressure gauge: if the pressure fluctuates, there may be a leak or an obstruction.

Upgrading your equipment is also a smart investment: variable-speed pumps and cartridge or glass filters reduce energy consumption and improve water circulation.

2. Take care of water circulation

Efficient circulation keeps the water moving, distributes chemicals and prevents debris buildup.
When water becomes stagnant, pressure increases unevenly in certain areas, which can cause microcracks or localized leaks.

Technical tips:

• Run the system for the number of hours recommended for your pool’s volume.

• Ensure the return jets are properly positioned to cover the entire pool surface.

• Avoid shutting down the system for long periods, especially during summer.

3. Maintain proper water chemistry

Unbalanced pH levels and excessive chemicals wear down the pool surface, joints and sealants.
Water that is too acidic or too alkaline can weaken concrete or corrode metal components, causing leaks over time.

Best practices:

• Check pH weekly (it should stay between 7.2 and 7.8).

• Use high-quality chemicals and apply proper doses.

• Avoid pouring chlorine directly onto pool surfaces.

4. Inspect the water level regularly

A constant drop in water level without visible evaporation is the clearest sign of a possible leak.

Check the following:

• Return, drain and skimmer joints

• Pump housing

• Visible hydraulic system connections

If the water level drops more than 1/4 inch per day, it’s best to schedule a professional leak detection test.
These tests use pressure, sound or dye and do not require breaking the pool surface.

5. Schedule periodic technical inspections

Technical maintenance should not be performed only when a problem appears.
Preventive inspections help detect seal failures, small leaks or valve wear before they cause major damage.

Specialized technicians can assess:

• Hydraulic system pressure

• Condition of internal connections

• Pump and filter performance

• Structural watertightness of the pool shell

Performing an inspection at least twice a year is the best way to ensure your pool stays free of leaks.

Common mistakes that can cause leaks

Even with good equipment, there are frequent mistakes that may compromise the structure or filtration system:

• Ignoring small bubbles coming from the return jets

• Using improper sealants without prior diagnosis

• Handling valves or pumps while the system is running

• Leaving the equipment turned off for long periods

• Not cleaning the filter after a storm or heavy-use season

Prevention is always more cost-effective than a structural repair.

Benefits of keeping your pool leak-free

• Water savings: prevents constant water loss and unnecessary expenses.

• Greater durability: materials and equipment last longer.

• Energy efficiency: the system works with less effort.

• Healthier water: fewer bacteria, algae and chemicals.

• Higher property value: a well-maintained pool always increases real estate value.

When to call a professional

If you notice persistent water loss, pressure fluctuations, pump noises or damp areas around the pool, it’s time to contact a specialist.

A professional diagnosis with pressure tests and detection equipment allows you to:

• Locate the exact leak

• Repair it without structural damage

• Prevent future leaks

Prevention is the best protection

Keeping your pool free of leaks is not a matter of luck, but of consistency.
With a modern system, periodic inspections and proper water chemistry, you can enjoy clean, stable and safe water all year long.
