Campbell -138517 Pvc Swing Check Valve 1 Inch Solvent Weld

Product Description

The CAMPBELL -138517 is a 1-inch PVC swing check valve designed to prevent backflow in low-pressure plumbing and fluid handling systems. The swing-style disc allows free forward flow and closes automatically when flow reverses, protecting pumps, distribution lines, and downstream equipment. The valve body is molded from corrosion-resistant PVC, making it suitable for water, irrigation, and light chemical service. Slip-style solvent weld ends allow direct connection to standard 1-inch PVC pipe using schedule-appropriate cement. Licensed plumbers and irrigation technicians are the primary installers of this valve type.

This valve is suited for residential and light commercial applications including water distribution, irrigation systems, sump pump discharge lines, and general plumbing drain and supply configurations. The clear PVC body supports in-line visual inspection of the valve disc without removing the valve from service. The solvent weld end style provides a permanent, leak-resistant joint and is appropriate for systems where disassembly is not required for routine maintenance.

Key Features

• PVC construction resists corrosion and chemical degradation in water and irrigation service
• Swing-disc mechanism allows full-bore forward flow with automatic closure on backflow
• Clear body allows visual inspection of disc position without service interruption
• Slip solvent weld ends connect directly to standard 1-inch PVC pipe
• Compact footprint suited for tight installation spaces in residential and commercial systems

Compatibility

Designed as an OEM-style replacement or new-installation swing check valve for standard 1-inch PVC solvent weld piping systems in water distribution, irrigation, and sump pump discharge applications.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable IPC and local plumbing code requirements. Shut off all flow and relieve system pressure before cutting into any existing line. Solvent weld connections require clean, deburred pipe ends and appropriate PVC primer and cement applied per the cement manufacturer instructions. Verify flow direction arrow on the valve body is oriented correctly before cementing, as swing check valves are not reversible once installed.
