Seal Minor Leaks Without Draining Your Pool

Lo-Chlor Leak Sealer is an advanced liquid formulation used to help seal minor cracks and leaks in swimming pool and spa surfaces and pipework.

It is ideal when you want to address small water-loss issues without emptying the pool or spa, supporting a faster return to normal operation with minimal disruption.

Fast acting and easy to apply, it helps minimise downtime and supports a quicker return to normal operation.

Seal minor pool leaks in surfaces and pipework without draining

Features & Benefits

  • Helps seal minor leaks – supports sealing of small cracks and leaks in many pools and spas.
  • Surface and pipework support – suitable for leaks in pool surfaces and circulation lines.
  • No draining required – helps address minor leaks without emptying the pool or spa.
  • Fast acting – results are often seen within 24 hours, depending on conditions.
  • Supports measurable water loss – suitable where loss is up to 3.5cm per day (50,000L pool).

How It Works

Leak Sealer starts as a liquid and disperses through the water to help reach the leak area. As it adjusts from its original high pH to normal pool water conditions, it begins to solidify in the presence of oxygen at the leak site.

This process helps create a sealing effect in minor cracks and small leak points, supporting improved water retention without structural changes.

Lo-Chlor Leak Sealer reacts with air to form a semi-permanent seal.
Leak sealing support for minor cracks and leaks

How to Use

  • Confirm the leak is minor and within the product’s recommended water loss range.
  • Remove any automatic pool cleaner from the pool.
  • Ensure the product does not pass through the filtration system (use a recirculate/bypass setting if available, or temporarily remove filter media where appropriate).
  • Apply Leak Sealer as directed on the label, based on where the leak is most likely occurring (surface area or pipework).
  • Allow circulation as instructed on the bottle label and check the water level after 24 hours.

Dosage & Coverage

  • Dosage: 1 litre treats 50,000 litres of pool water.

Important Usage & Compatibility Information

  • Intended for sealing minor leaks only.
  • Not suitable for vinyl liner pools.
  • Larger defects or ongoing water loss require professional plumbing or structural repair.
  • Ensure the product does not pass through filtration media during treatment.
  • Follow label directions and do not exceed the recommended dosage.

This product assists with minor leak sealing and does not replace structural repairs where required.
