Water heater and water tank failures can happen at any time, often without warning, and can cause substantial flooding and property damage if nobody is nearby to detect the leak right away. FloodMaster’s Water Heater Leak Alarm and Automatic Shut-Off Systems are ideal for minimizing water damage when these failures occur – even in plenum spaces, thanks to our new RS-094-MK6 kit.
Simply install the FloodMaster valve to the feed water line for the water tank and place the sensor puck on the floor, in a pan near the pressure relief valve drain tube, or in a position where the leaking water would first appear. When the FloodMaster sensor detects leaking water, the system will automatically shut off the feed water intake and sound an audible alarm. This closed-loop system disables the cold water supply line to hot water tanks or similar applications with basic plumbing installation. Units are powered by a standard 120 VAC wall outlet.
FloodMaster RS-094 Benefits:
- Lead-free ANSI/NSF 61 Annex G valve meets U.S. EPA Safe Drinking Water Standards
- Modified kits are available for installations involving plenum spaces, low-profile tanks and more
- Reduce or eliminate water damage and insurance claims
- Easy installation
- Additional sensors can easily be added to the system for a wider area of leak detection (additional wired sensor puck p/n RSA-100-008)
- Turns off water source automatically, even if you aren’t home to hear the alarm
- System is reusable – when the alarm sounds, fix the problem and reset unit for continued protection
- Made entirely of corrosion-free materials
- Plugs in to a standard wall outlet (120 VAC)
- Unit can interface with a home security alarm system or appropriate relay*
- Full port valve
Optional Accessories & Add-Ons**
- Electrical Plug Interrupter – Ideal for applications requiring that the electricity to the Power-Vent unit also be shut off when a leak is detected. Plugs into standard 120 VAC wall outlet; wires to RS-094 terminal block. For use with conventional Plug-In Power-Vent Gas Water Heaters. P/N RSA-600-001
- Wired Sensor Pucks – Up to 5 additional sensors can be wired to a single RS-094 Receiver box for a wider area of leak detection, with 8′, 25′, 50′ and 100′ cable lengths available. P/N RSA-100-008; -025; -050; -100. Order RSA-150-xxx for 1/2″ elevated sensors.
- Sensing Rope Kit – The Sensing Rope is ideal for use with low tanks, or for room perimeter and sub-floor leak detection applications. P/N RSA-175-810
- Auto Dialer – A convenient, low-cost add-on to send and receive automatic alerts whenever your FloodMaster system identifies a fault condition. P/N RSA-600-003
