Mueller Industries 101-107 Pvc Threaded Inline Check Valve 1-1/2 in

Product Description

The MUELLER INDUSTRIES 101-107 is a threaded inline check valve constructed from PVC, sized for 1-1/2-inch IPS connections. Check valves of this type allow fluid to flow in one direction only, automatically closing to prevent backflow when flow stops or reverses. This valve is a common component in plumbing, irrigation, and water treatment systems where backflow prevention is required. Installation is typically performed by licensed plumbers or experienced pipe fitters working on residential or light commercial water systems.

This check valve is suited for inline installation on 1-1/2-inch IPS-threaded pipe runs. The PVC construction makes it appropriate for cold and ambient-temperature water service, chemical-resistant applications, and environments where corrosion is a concern. It is commonly found in pump discharge lines, pool and spa circulation systems, and municipal water service tie-ins where backflow protection is required by code.

Key Features

• Threaded IPS connections for straightforward installation on standard pipe
• PVC construction provides corrosion resistance and chemical compatibility
• Inline check valve design prevents backflow automatically without manual operation
• 1-1/2-inch pipe size suits a wide range of residential and light commercial plumbing applications

Compatibility

Designed as an OEM-style replacement or direct-install check valve for 1-1/2-inch IPS-threaded PVC pipe systems in plumbing, irrigation, and water circulation applications.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply and relieve system pressure completely before cutting into any existing pipe or removing fittings. Use appropriate thread sealant or PTFE tape on all threaded connections and verify the flow-direction arrow on the valve body is aligned with the intended direction of flow. Do not install on hot-water lines without confirming the temperature rating of the valve is appropriate for the service conditions.
