Water & Gas Safety Valves

The WAGS valve is designed to shut off the water sup­ply (plus gas sup­ply for gas-fired heaters) in the event of a water leak from a hot water heater, thus min­i­miz­ing water dam­age and pos­si­ble gas leak­age. The valve can be installed on all styles of water heaters. The valve is fully mechan­i­cal and requires no exter­nal power supply.

When a water heater tank fails, the WAGS valve:

  • Shuts off the water supply
  • Shuts off gas on gas-fired heaters
  • Round-the-clock peace of mind!
  • Prevents costly water damage
  • Alleviates related gas safety concerns
  • Minimizes incon­ve­nience
