Prevent Structural Damage

Draining too fast or during high water tables can cause pools to 'pop' out of the ground. Always consult a pro for full drains.

Actionable Steps

Draining Safely

Check local laws for where you can discharge pool water. Submersible 'sump' pumps are the standard tool.

⚠️

Safety Warning: Never drain a vinyl liner pool completely without professional help, as the liner may shrink or shift.

Pro-Tip

Never drain your pool into a septic system. The massive volume of water can flood the tank and destroy your drain field in hours.
