Gauges

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

Select gauges:

with an appropriate range for the design specifications

that can be easily read in the available light conditions

Install gauges:

so they can be easily read (e.g., not facing the wall, or so high a ladder or stool is needed to access)

so they are not adversely affected by other equipment through heat conduction

Install surface-mount thermometers so that thermocouple for digital gauges is tight to the pipe and wrapped with insulation to exclude ambient temperature

Install wet-mount thermometers so they are not in an air pocket (e.g., install on side of pipe, not on top of side-plumbed tanks)

Install pressure gauges so they are not adversely affected by turbulent flow and vibration

Install gauges according to manufacturer specifications and applicable code (e.g., IPC, IRC, NFPA 70)

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

Install a water cut-off valve on both sides of the gauge

When connecting non-ferrous metal pump to existing ferrous piping, install a dielectric union or a plastic-lined steel nipple a minimum of 4" long to connect the two piping systems

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