Q: "How do the Floodstop FS3/H-90 unit and the Intelliflow Series A2C-M differ? I am looking for a water leak alarm and am not certain which one to purchase. Thanks. Stefan."
Answer: All that I know about the Intelliflow water leak alarm is from Internet reviews and from the manufacturer's website.
I recommend you choose the Floodstop unit unless you are looking for a main water valve shut off such as the WaterCop that also uses individual water sensors. My recommendation is based on personal experience, customer feedback, repeat large orders from condo associations and plumbers and internet reviews. The IntelliFlow negative reviews are numerous on customer postings while the FloodStop Washing Machine units are all positive comments.
Safe Home Products has sold the Floodstop units since 2003 with only two customer problems. One customer had difficulty getting the automatic water valve on his hot water heater Floodstop to re-open after it closed when his water heater began leaking on the floor. The second person had a unit that was defective from the start, the actuator did not work properly. We have literally sold thousands of the different models with only praise.
FloodStop comments were all positive and include:
- Easily installed: less than 30 minutes.
- Off button: able to manually shut off water without reaching behind the washer.
- Works great.
- Does what it is supposed to do: protects from leaks.
IntelliFlow negative comments are related primarily to water flow:
- electronics fails completely sometimes in less than one year.
- electronics cause the unit to open and close the valves repeatedly causing knocking sounds.
- electronics cause the unit to cycle on and off with high efficiency machines
- electronics cause the unit to shut off the water before the extended high efficiency cycle (can often be over an hour on my Kenmore) is complete.
Basic descriptions of both the Watts IntelliFlow and the Floodstop follow.
Intelliflow Automatic Washing Machine Water Shutoff Valve Series A2C-M
The Watts IntelliFlow Automatic No. 2 (A2C-M) has a state of the art electric current sensing device. Water valves open when the washer is turned on and the current flow to the washer is sensed. After the full wash cycle is completed, the device senses the lack of current and closes the water valves. The logic is that an automatic operation protects against water damage if a washing machine inlet hose breaks when no one is around. Constant water pressure can cause traditional washing machine hoses to burst.
Also the leak sensor senses leaks during the wash cycle and shuts off the water valves to prevent flooding.

# Circuit breaker requirement: 15 amp. GFI *
FloodStop Washing Machine Unit:
Automatically shuts off water to the washing machine when water leaks from a hose or the machine and sounds an alarm. All other household plumbing fixtures and appliances are unaffected. Installation is simple.
To install, connect the two Floodstop Valves to the hot and cold water supply lines. Mount control unit to wall. Place sensor(s) on floor. Units are operated by either by 120 vAC adapter (included), Batteries OR BOTH!
NOTE: DO NOT PLACE SENSOR DIRECTLY ON METAL PAN OR DAMP FLOOR. If no water is present and sensor sounds alarm, place paper towel or cloth under sensor to "insulate" against dampness of floor or metal of pan. Once the paper or cloth gets wet, the sensor will activate the shut-off and sound the alarm. Sensor will sound if placed on metal.
Kit Contents: everything you need to protect your property:
* Two 3/4" motorized ball valves with hose fittings to install on both hot and cold water inlets.
* Water sensor to place on the floor. If there is a washing machine drain pan, purchase another sensor to place inside pan.
* Control Unit to be mounted with screws or Velcro (included).
* AC Adapter and/or batteries for power source.
Similarities: Both shut off water.
Differences: How and by what means the valves are shut.
- IntelliFlow: Washer water valves are opened and closed at the beginning and end of what the Intelliflow believes is the washer's cycle, as evidenced by a sensor for electric current. In other words, the Intelliflow shuts off hot and cold water valves when the washer stops using electricity and/or when the moisture sensor senses a leak when the unit it operating.
- The Floodstop shuts off hot and cold water valces when a leak is sensed during machine operation, when a hose breaks, when the pan beneath the machine has water leaking into it from a washing machine leak, etc.when the washing machine is operating or when it is there with water sitting in the hoses.
I hope this has been helpful. Thanks for your question.
Sincerely,
Barbara
