FAQs: RS-094 Water Heater Leak Alarm & Shut-Off System

FloodMaster® RS-094 systems detect water heater and water tank leaks and automatically turn off the water supply to the appliance.

Does the RS-094 meet the new Safe Drinking Water Standard (effective 1/1/14)?

Yes, the RS-094 full port valves are certified to NSF/ANSI 61 Annex G and meet the new lead-free requirements of the Federal Safe Drinking Water standard.

Does the actuator box on the RS-094 need to be installed in a particular orientation?

No, the actuator box mounting was designed so the actuator box could be installed on the mounting pad in any orientation.

Can I add additional sensors to my RS-094 system?

Yes! The actuator box terminal block has two set of portals for sensor wiring and can accommodate multiple wires to each slot. Daisy chaining or electrical splicing in additional sensors to expand the area of leak detection is also allowable. At least 6 total sensors can easily be accommodated in a single system. Order additional wired sensors with part number RSA-100-008. (Please be sure to consult your local electrical codes.)

What kind of wire should I use for the relay output contact on the RS-094?

Standard alarm wire (22 AWG, 2 wire) is acceptable for this connection.

How long does it take the RS-094 valve to cycle?

The RS-094 actuator opens and closes the full port valve in approximately 45 seconds.

After an alarm, how do I reset my RS-094 unit to begin the flow of water again?

Confirm the sensor is dry and the press and release the Reset button to begin the flow of water again.

What happens to the RS-094 valve position when there is a power failure?

The RS-094 unit will remain in whatever position they were in prior to the power failure (open or closed).

If the FloodMaster unit detects a leak in a water heater and shuts off the cold water intake to the water heater, what will happen to the water inside the tank? Will it leak out or stay in the tank?

The water inside the tank may stay there (inside the tank) if a sufficient vacuum has been set up in the system. The worst-case is that the water inside the tank will leak out, but no more water will enter the tank since the FloodMaster valve is closed. The maximum amount of water that will leak out into the premises is, therefore, the maximum capacity of the tank itself. This is better, however, than a continuing flow of water from the intake cold water line through the malfunctioning water heater tank into the premises (in the absence of a FloodMaster valve), especially if the occupants of the premises are not on-site and water flows freely for an extended length of time.

Is there any restriction as to the energy source of the water heater unit when installing a FloodMaster RS-094 valve?

There are no such restrictions.

Does the valve body on the RS-094 need to be installed in a particular orientation?

No, you can install the valve in any orientation.
