Zurn p6900-tmv-xl Lead Free Thermal Mixing Valve

Product Description

The ZURN p6900-tmv-xl is a lead-free thermostatic mixing valve designed for potable water systems in residential and commercial plumbing applications. The valve blends hot and cold supply lines to deliver a controlled, tempered water output, protecting end users from scalding while maintaining consistent outlet temperatures. It is constructed with a brass body and FKM fluorocarbon Viton seals, rated for flow rates between 0.5 and 4 GPM. Operating pressure is rated up to 145 psi, with a working temperature range of 95 degrees F to 115 degrees F. This valve meets ASSE, CSA, and NSF standards, making it suitable for code-compliant installations where lead-free compliance is required.

This mixing valve is intended for plumbing applications where tempered water delivery is required at point-of-use fixtures or equipment. Compression connections on both the 3/8-inch inlet and 3/8-inch outlet allow for straightforward integration into existing supply lines. It is commonly installed by licensed plumbers in restroom, lavatory, and light commercial fixture setups where anti-scald protection and water temperature control are critical to occupant safety and code compliance.

Key Features

• Lead-free brass body construction meets potable water safety requirements
• Flow rate range of 0.5 to 4 GPM suits single-fixture and light multi-fixture applications
• 3/8-inch compression inlet and outlet connections for tool-assisted, leak-resistant installation

Compatibility

Designed as an OEM-style replacement or direct-install thermostatic mixing valve for 3/8-inch compression potable water plumbing systems requiring lead-free, code-compliant tempered water delivery.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and relieve system pressure before beginning any connection work. Compression fittings require proper seating and appropriate hand tools to avoid over-tightening or thread damage. Verify inlet hot and cold supply orientation prior to final connection and test for leaks and correct outlet temperature before returning the system to service.
