994RPDA Watts

Reduced Pressure Detector Assemblies, Stainless Steel

Series 994DCDA Reduced Pressure Detector Assemblies prevent the reverse flow of fire protection system substances from being pumped or siphoned into the potable water supply. The 994DCDA incorporates a meter to detect ground leaks and unauthorized illegal taps, greatly reducing annual water expenses. It consists of a stainless steel body, stainless steel internal parts, thermoplastic check valves and a bottom-mounted relief valve. Series 994DCDA is half the weight of competitive designs, and its short lay length makes installation and maintenance simple and easy. It is ideal for installation on fire protection systems. Check with local water authorities for installation requirements. Maximum Working Pressure: 175psi (12.06 bar)


  • Torsion spring check valves provide maximum flow at low pressure drop
  • Detect costly underground leaks and unauthorized water use
  • Stainless steel body provides strength, resists corrosion, and weighs less than competitive designs
  • Bottom-mounted relief valve reduces clearance requirements when installed against an outside wall
