Wireless Plumbing Leak Detection System with 1" Automatic Shutoff Valve & Wi-Fi Hub


The Wasens RSC-900-AW is a wireless plumbing leak detection and automatic water shut-off system with app-based notifications and control. It also monitors for near-freezing temperatures that could cause burst pipes. This kit includes the following commercial-grade components:

  • 1 – Wi-Fi communications hub with 2 AA batteries
  • 1 – 110V power plug (hub)
  • 2 – Wireless water sensors with 2 AAA batteries each
  • 1 – 1" full port lead-free shut-off valve
  • 1 – Actuator with 4 CR123A (3V) batteries
  • 1 – Long parallel mounting adaptor (valve/actuator)
  • 1 – Short perpendicular mounting adaptor (valve/actuator)
  • 1 – Emergency key (valve/actuator)
  • Automatically shuts off the main water supply line when a fault is detected (water leak or near-freezing temperature) and sends an app-based notification to any iOS or Android smartphone
  • Easy to install, easy to use
  • Battery operated to maintain protection during power outages (up to 8 hours)
  • Supports up to 64 total water sensors, shut-off valves and signal repeaters for wide areas of leak detection
  • Supports multiple actuators for both hot and cold water lines; rated for indoor and outdoor use
  • Operates via its own wireless system network – does not rely on local wi-fi
  • Administer multiple systems from a single app and create multiple "Zones" to monitor/control designated areas or plumbing subsections within a single system
  • Cloud-based Central Monitoring Station access is available for commercial multi-unit applications

RDT recommends that installations be completed by a licensed plumber to ensure that all local code requirements are followed.

You are currently viewing the RSC-900-AW-WIFI-1 kit, which features a 1" automatic shut-off valve and Wi-Fi communications hub.

Standard Base Kit Configurations:

Choose an Ethernet hub for enhanced Internet connectivity, or the Wi-fi version for greater installation flexibility. Choose the RSC-900-W for wireless leak detection without a shut-off valve and actuator, for applications where interrupting the water flow is either not required or not desirable.
