Introduction
Pool plumbing is often connected to external water sources or chemical dosing lines. Anti-siphon devices are crucial to prevent potentially contaminated water from flowing back into the clean water supply.

How Does It Work?

• Backflow preventer (Anti-siphon): Ensures that water cannot reverse direction if line pressure drops.
• Installation above the pump: Gravity helps stop water from draining backward into the supply line.

Important Notes

Regular inspections of these devices are necessary. A malfunctioning backflow preventer can result in chemicals or polluted water contaminating drinking water sources.
