METAL TAG REQUIREMENTS FOR WATER HEATERS
The Board of State Examiners of Plumbers and Gas Fitters (“Board”) has voted to interpret the language of Chapter 142, Section 17 of the Massachusetts General Laws stating:
Water tanks, plainly marked by the manufacturer, by stamping into the metal of the tank, or on a metal plate permanently attached to the tank, in a conspicuous place.
The metal foil tag attach to most water heaters meet these requirements.
Most manufacturers now affix a foil tag permanently to the outside jacket of their water heaters in lieu of attaching it to the actual vessel itself.
