The return of warm weather marks the long-awaited moment to reopen your pool! A proper opening ensures you can quickly enjoy clean, balanced water. However, the opening steps vary slightly depending on whether your pool is inground or above ground.
Preparing for Opening: The First Steps Common to All Pools
Whether your pool is inground or above ground, some common steps are essential to start the season off right.

- Remove the cover: If you used a winter cover, take it off carefully to prevent debris from falling into the water. Clean it and let it dry before storing it.
- Inspect the pool: Check the liner or pool surface for any cracks or damage. Make sure the outer structure shows no signs of wear or damage.
- Clean the water and surfaces: Use a skimmer to remove floating leaves and debris, then brush the walls and floor to get rid of any residue that built up over the winter.
- Check the equipment: Make sure the pump, filter, skimmer and return jets are in good condition before restarting the system.
- Fill the pool: Top up the water level to about three-quarters of the skimmer if needed before turning on the filtration system.
Inground Pool: Start-Up and Water Treatment
Opening an inground pool involves several steps:
1. Installing Pool Fittings and Equipment
- Remove the plugs from the return jets and screw the fittings back in.
- Reinstall the inner ring and return jet eyeball.
- Put the skimmer baskets back in place and check the condition of the filters.
- If your pool is equipped with a lighting system, reinstall the components according to the manufacturer’s instructions.
2. Preparing and Connecting the Equipment
- Pump and filter: Screw in the pump’s drain plugs and make sure all connections are tightly secured.
- Filter: Screw the drain plug back in and ensure the unions are properly sealed. Apply Teflon tape to the pressure gauge before reinstalling it.
- Heater (if applicable): Check the heater connections and make sure it is properly connected to the filtration system. Before turning it on, wait until the water is circulating properly and is clean.
- Salt system: Reconnect the cell and leave the control panel turned off until the water is clean and balanced.
3. Start-Up and Water Treatment
- Start the pump, making sure the water is circulating properly through the system.
- Test and adjust the pH (ideally between 7.2 and 7.6), alkalinity, and hardness.
- Apply a shock treatment to eliminate bacteria and prevent cloudy water.
- Add an algaecide to prevent algae growth from the start of the season.
Above Ground Pool: Specific Steps to Follow
Opening an above ground pool follows a similar process, with a few specific differences:
1. Installing Pool Fittings and Equipment
- Remove the winter plugs from the return jets and screw the fittings back in.
- Reinstall the inner ring and the return jet eyeball.
- Put the skimmer flap and basket back in place.
- If your return jet includes a light, reconnect the light and make sure the breaker is off before plugging in the power cord.
2. Connecting the Plumbing and Equipment
- Pump: Install the pump and screw in the drain plugs. Connect the hoses, making sure to lubricate the seals properly to prevent leaks.
- Filter: Put the inspection cover back in place, screw in the drain plug, and make sure all connections are secure.
- Heater (if applicable): Reconnect the heater and ensure it’s properly hooked up to the filtration system. Before turning it on, wait until the filtration is running normally and the water is clean.
- Salt system: Reinstall the cell and keep the control panel turned off until the water is balanced.
3. Start-Up and Water Treatment
- Fill the pool up to three-quarters of the skimmer.
- Test and adjust the water’s chemical levels.
- Add a shock treatment and use an opening kit to ensure clean, balanced water.
