The 2"- 4" 40/50 Air Gap Drainage System will capture and evacuate mild water discharge from the Relieve Valve caused by daily fluctuation in system/supply pressure.

The Air Gap drainage system will NOT capture and evacuate the maximum discharge caused by catastrophic valve or system failure. An auxiliary drain (separate and independent of the Air Gap Assembly) is REQUIRED and MUST be properly sized for the Maximum Relief Valve Discharge Rate (see specifications below).

The Air Gap assembly can be used on:

  • 2 1/2" - 4" Deringer 40/40G
  • 2 1/2" - 4" Magnum 40/40G
  • 2 1/2" - 4" Deringer 50/50G

2"- 4" 40/50 Air Gap Assembly includes:

  • Air Gap Shield
  • Air Gap Reducer
  • Air Gap Bracket
  • All Required Hardware

 

NEVER install an RP or RPDA in a location where any amount of discharge from the Relief Valve will cause property damage. For an indoor, pit, vault, mechanical room or enclosure installation of an RP or RPDA, an auxiliary drain (separate and independent of the Air Gap Assembly) is REQUIRED and MUST be properly sized for the Maximum Relief Valve Discharge Rate (see specifications below) corresponding to the system/supply pressure. Backflow Direct shall not be responsible for any damage caused by lack of auxiliary drain, location of auxiliary drain or undersized auxiliary drain. If the buyer is unwilling to meet this requirement please DO NOT purchase this product.
