Pool Main Drain

A main drain is a suction outlet located at the bottom of a pool that assists in water circulation and debris removal.

Function of the Main Drain

The main drain works with the skimmer and pump to pull water from the bottom of the pool, preventing stagnant areas and improving filtration efficiency.

Safety and Maintenance

  • Ensure the main drain cover is secure to prevent entrapment.
  • Regularly check for debris buildup and clean as needed.
  • Comply with safety regulations like the Virginia Graeme Baker Act (VGBA) to prevent accidents.
