Start with the water
Bring the water to the right level, balance it, and record where the water line sits. That baseline makes it easy to spot a leak later.
Look over the equipment
Check the pump, filter and heater connections for drips or damp spots. Look at skimmer baskets, returns and lights for cracks or loose fittings.
Listen for air in the pump and watch the pressure gauge for unusual changes.
Keep an eye on it
Note the water level every few days in the first month. If it drops faster than expected, we would be glad to take a look.
