Pool Leaks and Chlorine Lock

Poolside by CGT recommends identifying water loss and reduced chlorine effectiveness as they are common issues that can impact pool performance and water clarity.

Pool Leaks

Leaks may occur from punctures in vinyl liners, plumbing failures, or ground movement.

The bucket test is commonly used to determine whether water loss is due to evaporation or leakage.

Chlorine Lock

Chlorine lock occurs when chlorine becomes unavailable for sanitization.

This can occur when chloramines build up in the pool.

Shock treatment or partial water replacement may be required.

For help with cloudy pool water, see our guide on clarifiers, flocculants, and enzymes.
