Hayward PSV3SDGR 3-Port PVC Diverter Valve (1.5″ → 2″)
The Hayward PSV3SDGR is a 3-port PVC diverter valve used to direct water flow between different paths — ideal for pool and spa plumbing setups where you need to alternate between systems like filtration, solar heating, spa circuits, or bypass loops. The valve’s durable PVC construction and flexible port configuration make it a reliable choice for many residential and commercial pool systems.

When & Why to Use PSV3SDGR
This valve is ideal when you need to redirect flow between multiple pool or spa circuits — for example, switching between filtration and solar heating, isolating equipment for service, or diverting water between spa and pool loops. Because of its durable PVC construction and versatile port sizes, it fits cleanly into typical 1.5″–2″ PVC plumbing setups without extensive re-piping. A simple handle turn is all it takes to change flow direction, making system operation more flexible and maintenance easier.
Installation & Maintenance Tips
- Before installation, ensure plumbing pipe size and connection type (slip, spigot or threaded) match the valve’s ports.
- Glue or thread the valve into the plumbing per manufacturer guidelines; allow solvent welds to cure fully before pressurizing the system.
- Use a pool-safe lubricant on union o-rings if applicable, to ensure a tight seal and ease future removal.
- Manually rotate the handle only when the pump is off to prevent pressure shock and ensure proper sealing between ports.
- Periodically inspect valve body and seals for cracks, leaks, or wear — replace if deteriorated to maintain system integrity.
