Jandy 3406 Space Saver Diverter Valve – Compact 3-Port Pool Valve

Part # 3406 — a compact diverter valve from Jandy’s Pro Series, designed for tight-space plumbing applications while delivering full-flow performance.

Key Features

Compact 3-port design with 1½″ to 2″ ports — ideal for equipment pads with limited space.
Durable CPVC construction engineered for long-term exposure to pool chemicals.
Positive-seal diverter mechanism ensures smooth operation and leak-free performance.
Lubrication-accessible without disassembly for simplified maintenance.
Provides full flow capacity despite its reduced footprint.

Typical Applications

Commonly used to route water flow between multiple paths such as pool/spa return lines, heater bypassing, and zone routing in multi-feature pools—especially where plumbing space is tight.

Installation & Compatibility Notes

Turn off pump power and relieve system pressure before installation. Prepare plumbing for 1½″–2″ ports and solvent-glue or thread connections per local code. After installation, verify smooth handle movement, proper sealing, and correct water flow direction.

Why Choose This Diverter Valve?

The 3406 Space Saver Valve provides strong flow handling in a compact body, making it ideal for installations where standard-size valves cannot fit. Its durable design and reliable internal sealing support long-term, leak-free operation.

Maintenance Tips

Rotate the diverter handle periodically to prevent sticking.
Inspect and lubricate internal O-rings annually with a pool-safe lubricant.
Check glued or threaded connections for leaks after seasonal changes or system maintenance.
Replace the valve if cracks, warping, or persistent leaks occur.
