Stop Laundry Room Floods Before They Start

Engineered for multi-family, commercial, and residential applications, this recessed wall-box system delivers 24/7 leak defense. Featuring dedicated hot and cold automatic shut-off valves alongside integrated water hammer arrestors, it stops catastrophic water damage at the source. 

Key Technical & Mechanical Features

  • Integrated Rough-In Assembly: Recessed wall-mount outlet box housing a dual-port 1/2" full-port brass motorized ball valve assembly, integrated receiver module, low-profile puddle sensor with 8' factory lead wire, and finished faceplate.   
  • Code-Compliant Water Hammer Protection: Dual integral ASSE 1010-rated water hammer arrestors factory-fitted directly on both hot and cold supply lines to mitigate hydraulic shock, eliminate pipe chatter, and protect inline joints.   
  • Automated Cycle & Anti-Seize Exercise: Microprocessor-controlled automatic exercise routine cycles both valves bi-weekly to prevent mineral accumulation, scale buildup, and valve seizure over extended static periods.   
  • Local Annunciation & Interface: Wall-mountable control interface featuring an 86 dB audible alarm, visual LED fault indicators, and a one-touch manual reset toggle to return to normal operation without component replacement.   
  • BMS & Auxiliary Integration: Low-voltage output contacts facilitate straightforward tie-in to building automation systems (BMS), third-party alarm panels, or local shut-off networks.
  • Risk Management Alignment: Engineered to meet insurer risk mitigation standards for multi-unit high-rise properties, qualifying owners and HOAs for deductible credits and policy discounts. 

Target Applications & Project Delivery

  • Multi-Family High-Rise & Mid-Rise (New Construction): Standardized, rough-in ready unit drops directly into 16" on-center stud bays, minimizing installation labor while securing stack risers against washing machine hose bursts and supply line failures.
  • Commercial Tenant Improvements & Mixed-Use: Direct point-of-use risk mitigation for residential floors situated over occupied retail spaces, amenity areas, or high-value mechanical rooms.
  • Retrofit & Building Modernization: Sized to replace conventional passive washing machine valve boxes during unit turnovers, laundry room refits, or building-wide plumbing infrastructure upgrades.
