What to Check Before Starting Up Your Pool After Months of Inactivity

If your pool has been out of use for weeks or months, it is not enough to simply turn on the system and start swimming. Knowing what to check before starting up your pool is essential to prevent structural damage, avoid water quality issues, and protect your filtration equipment. Starting the season without a proper inspection can lead to costly repairs and delay your enjoyment.

Check for Leaks Before Starting Your Pool
Carefully inspect the structure, connections, skimmers, and pipes to rule out visible leaks. Even a small leak can waste large amounts of water and disrupt chemical balance, forcing you to spend more on maintenance products.

Tip: If the water level drops without any clear reason, perform the bucket test to confirm if there is a leak, or call a professional for assistance.

Clean and Service the Filters
After months without use, filters can accumulate sediment, leaves, insects, and mineral deposits that reduce their filtering efficiency.

What to Do:

• Backwash sand filters to remove impurities.

• Clean or replace cartridges if worn.

• Check for cracks, broken parts, or damaged seals.

Test the Water Before Turning on Your Pool
Water can deteriorate even if the pool has been covered, leading to algae growth, bacteria, or unpleasant odors.

Recommendation:

• Measure and adjust pH, alkalinity, and chlorine before the first use.

• If the water is cloudy or green, apply a shock treatment and run the filtration system continuously for 24 hours.

Inspect Electrical Equipment and Pumps
Make sure pumps, timers, heaters, and lighting systems are functioning properly. Electrical failures can damage equipment and pose safety risks to swimmers.

Knowing what to check before starting up your pool after months of inactivity is the best way to extend its lifespan and ensure a safe, clean, and trouble-free season.
