Installation

Proper installation ensures optimal performance and longevity.

Select location: Choose accessible position in plumbing line with adequate clearance.
Prepare pipes: Cut pipes cleanly and deburr ends for proper fit.
Apply primer and cement: Use PVC primer and cement following manufacturer instructions.
Connect valves: Insert pipes into valve ports with quarter-turn during connection.
Align handle: Ensure handle moves freely through full range of motion.
Pressure test: Check for leaks before putting system into full operation.

WARNING! Allow proper cure time for cement before applying pressure. Wear safety glasses during installation.

Operation

Simple manual operation for precise flow control.

Identify flow direction: Arrow on valve body indicates primary flow direction.
Adjust handle: Turn handle to desired position for flow control.
Set positions: Common positions include ON, OFF, and intermediate settings.
Lock position: Some models feature locking mechanism for secure settings.

CAUTION! Do not force handle beyond stop points. Operate only when system pressure is normal.

Flow Control: Adjust handle to regulate water flow between connected systems. Diverter valves can split flow between multiple outlets. Union connections allow for easy removal and service without cutting pipes.

Connecting to Pool Systems

Compatible with standard pool and spa plumbing systems.

Identify system requirements: Determine valve type needed (2-way, 3-way, diverter).
Match pipe sizes: Ensure valve size matches existing plumbing.
Plan flow direction: Install with arrow indicating desired flow direction.
Support plumbing: Use proper hangers and supports to prevent stress on connections.

Tip: Install unions on both sides for easy future maintenance and replacement.

Maintenance Procedures

Regular maintenance ensures reliable operation and extends valve life.

Visual inspection: Check for cracks, leaks, or damage monthly.
Handle operation: Ensure smooth movement through all positions.
Seal inspection: Check O-rings and seals for wear or deterioration.
Cleaning: Remove debris from valve exterior and operating mechanism.
Lubrication: Use pool-safe lubricant on moving parts as needed.

WARNING! Always shut off pump and relieve system pressure before performing maintenance.

Safety Features

Positive stops prevent over-rotation. Locking positions secure valve in desired setting. Durable construction withstands normal operating pressures.

Care & Cleaning

Use mild soap and water for cleaning. Avoid harsh chemicals or abrasive cleaners.

CAUTION! Do not use petroleum-based products or solvents that may damage PVC material.
