1: SHUTS DOWN WATER SUPPLY
When a water heater leaks, and the tank pressure drops about 20
PSI, the WHID will trip and
LOCK CLOSED,
preventing any further water supply to the tank.
2: HOLDS WATER IN WATER HEATER
When a leak occurs and the WHID locks closed,
the DUAL CHECK VALVE creates a VACUUM
preventing  water from leaking out.
