Why Proper Pool Opening Matters

Skipping steps or rushing the process can lead to expensive repairs, cloudy water, or even unsafe swimming conditions. The key to a smooth transition lies in following a proven pool opening checklist and using quality pool opening supplies.

Step 1: Remove the Pool Cover (and Clean It)

Start by clearing off leaves, debris, or standing water from the pool cover. Use a pool cover pump or leaf blower to make the job easier.

✅ Pro Tip: Don’t skip cleaning your pool cover before storing it—it’ll last longer and save you money.

Step 2: Inspect the Pool Water Level

Your water level may have dropped over the winter. Refill the pool to halfway up the skimmer opening using a garden hose.

Step 3: Reconnect Pool Equipment

Reinstall and reconnect:

• Skimmer baskets

• Return fittings

• Pool pump

• Pool filter

• Heater (if applicable)

• Chlorinator or salt cell (if using a saltwater system)

Check for visible wear or damage. If anything is cracked or leaking, now’s the time to order replacement pool parts.

Step 4: Remove Winter Plugs and Add Drain Plugs

Remove any winterizing plugs and ice compensators. Reinsert the drain plugs into your pump, filter, and heater.

Step 5: Prime the Pool Pump & Start It Up

Fill the pump housing with water, close the lid, and turn on the system. Watch for proper water flow and listen for unusual sounds. If your pump won’t prime, shut everything off and troubleshoot before proceeding.

Step 6: Shock the Pool and Test the Water

Use a pool shock treatment to kill bacteria and clear up cloudy water. Wait until the chlorine level drops to safe levels, then test and balance:

• pH (7.4–7.6)

• Total alkalinity (80–120 ppm)

• Calcium hardness (200–400 ppm)

• Cyanuric acid (30–50 ppm for chlorine pools)

Step 7: Clean & Vacuum the Pool

Brush down the walls and vacuum the bottom using a manual or automatic pool cleaner. Remove any leftover debris and keep the filter running for 24–48 hours.

Pro tip: A robotic pool vacuum can save you hours of manual cleaning.

Step 8: Add Pool Opening Chemicals

Once your water is clear and balanced, it’s time to add the final chemical treatment. Many brands offer pre-measured pool opening kits that include everything you need.

Final Checklist for Pool Opening Success

• Cover removed and cleaned

• Equipment reinstalled and leak-free

• Water level topped off

• Chemicals balanced

• Pool vacuumed and ready
