Mixing Valves

Verify current plumbing infrastructure is sufficient to support the installation(s) and is leak-free

Install mixing valves at as many locations as necessary to deliver safe and adequate hot water

Install equipment in compliance with applicable code (e.g., NFPA 70, IRC, IBC, IMC) and manufacturer specifications

If conflict exists between code and manufacturer specifications, apply the more restrictive requirement

Install valve and plumbing to allow for inspection, maintenance, and replacement of the appliance and its components, without disturbing other installed equipment, controls, piping, and components, other than what requires repair/replacement

Install a separate water cut-off valve for both the hot and cold incoming water lines

Install check valves on the hot and cold water supply lines upstream of the mixing valve

Install mixing valve with a heat trap or at a distance from heat sources sufficient enough to prevent scaling or damage to the valve

Install temperature gauges on hot, cold, and tempered supply water lines within sight of the mixing valve

Install controls and sensors in accordance with manufacturer specifications and applicable code (NFPA 70)

When controls are low voltage, separate the low voltage and line voltage wiring

Install dielectric unions when connecting copper to galvanized steel piping in accordance with the IRC and manufacturer specifications

Set discharge temperature to not exceed 120 degrees or as prescribed by local code

Provide occupants/owners with user's manual, warranty information, installation instructions, and installer contact information
