Pentair 263028 – 3-Way Diverter Valve 2" x 2½"

Product Overview

The Pentair 263028 is a three-port diverter valve designed for pool and spa plumbing systems. It allows one inlet and two selectable outlets (or vice-versa) to redirect flow efficiently through piping configurations that require turning or splitting the flow path.

Key Features

• Three-port PVC/CPVC body with 2" nominal internal diameter and 2½" spigot outside diameter.
• Fiberglass-reinforced handle for durable manual operation.
• Maintenance-free diverter seal for long service life in chemical-exposed environments.
• High flow rate design and rated for standard pool system pressures.
• Directional arrow molded into body to assist with correct installation.

Technical Specifications

• Part Number: 263028
• Port Configuration: 3-way (one inlet, two outlets) or reversed as required
• Connection Sizes: 2" nominal ID x 2½" outside diameter spigot/slip ends
• Body Material: PVC/CPVC (suitable for pool chemical service)
• Maximum Pressure Rating: Up to 150 psi in typical pool plumbing applications

Applications & Fitment

This diverter valve is suitable for redirecting water flow in pool and spa systems such as heater bypasses, solar panel loops, or automated routing of return lines. It is commonly used where the installer needs to manually or automatically switch between flow paths without using multiple valves or increasing complexity.

Installation Instructions

• Shut off the pump and relieve pressure in the plumbing before servicing.
• Cut the main line and dry-fit the valve body to confirm orientation and alignment with piping runs.
• Use appropriate primer and solvent cement based on material type; insert piping fully and hold until joint sets.
• Ensure the handle moves freely and the flow direction arrow aligns with the intended inlet position.
• Restore system flow and inspect for leaks. Cycle the handle through its diverter positions to verify smooth operation.

Troubleshooting

• Leak at valve joint: Confirm proper solvent bond at spigot ends and verify alignment of mating surfaces.
• Handle difficult to turn: Check for internal debris or misalignment of piping; ensure valve was not over-tightened during installation.
• Insufficient flow to selected outlet: Verify the flow path is correctly configured and that no closed port is unintentionally in the circuit.

Maintenance Tip

Inspect the valve handle and body annually for signs of fading, cracking or chemical damage. Ensure the diverter seal remains free of buildup and rotates fully between positions. Family-owned pool systems benefit from keeping this valve accessible for periodic manual cycling and lubrication of the handle pivot point to maintain optimal service life.
