What maintenance step can help prevent pool leaks?

Regularly inspecting the pool liner and plumbing is essential in preventing pool leaks. This proactive maintenance step allows for the early detection of any potential issues, such as tears in the liner, cracks in the structure, or deterioration in the plumbing system. Addressing these problems promptly can help prevent water loss and avoid costly repairs that may arise from undetected leaks. By routinely checking for signs of wear and tear, pool operators can maintain the integrity of the pool's components, ensuring a safe and efficient swimming environment.

The other options, while important for other aspects of pool maintenance, do not directly contribute to leak prevention. Frequent application of pool chemicals does not address structural integrity or damage. A stronger pool cover may help reduce debris, but it doesn't prevent liner or plumbing issues. Similarly, shocking the pool weekly is crucial for maintaining water quality but has no impact on preventing leaks.
