Essential Info

Avoid costly water damage repairs with the FloodStop FS1/4C Icemaker/Water Filter Valve Shutoff Kit with Water Leak Prevention functionality. Designed for both residential and commercial dwellings, this kit uses an automatic 1/4-inch compression fitting motorized ball valve powered by an AC/DC adaptor (or 4 AA batteries) to shut off the water supply whenever a water filter or ice maker leaks. When using the AC/DC adaptor, the 4 AA batteries will serve as a battery backup in case of a power outage.The non-intrusive devices can be installed in as little as 10 minutes and does not require a professional installer.

This kit includes everything needed to protect your property from costly water-leak damage: a valve installed on the water intake valve, a water sensor to be placed on the floor, and the control unit, which is mounted to your wall with the included screws. In addition, the FS1/4C also has a built-in audible alarm that will sound off an alert when a leak is detected. The included control unit has two output contact wires and plugs with 6" leads and can easily integrate into an INSTEON or X10 based network.

    My built-in ice maker developed a leak after it was installed. I looked into other (more expensive) devices and systems that warn the homeowner of a water leak, but they do nothing about the leak. Bought this unit and had it installed when the plumber tried to fix the leak. He did not (fix the leak) and the unit reliably alarmed and shut off the water! I finally corrected the water line problem myself. Hopefully, will not need the shut-off system but now I have peace of mind. Easy to install, works as advertised and inexpensive. HIGHLY RECOMMENDED.

    install was easy, compact so it did'nt take up much room, tested and worked very well, delivery was with in time noted
    KATHERINE -- honolulu, HI   9/13/2012
    No difficulty installing.

    Had a little trouble with misplaced O-ring--not in kit, didn't realize wasn't there until kept leaking after multiple tries and looked at the other shutoff kits I bought for other products. HOwever, now working well and ANY moisture sets it off.

    Easy to install and works as advertised. I'll be getting additional valves for my dishwasher, hotwater heater, and washing machine. My only minor complaint is that the polarity of the wiring on the motor was reversed. Water didn't close the valve and I just swapped the wires on the motor and re-soldered them, problem fixed. With correct wiring, this thing works perfectly. A single drop will set the alarm off and shut off the water supply to my ice-maker.

    Nice product, fast shipping
    XAVIER -- san francisco, CA   2/26/2010

    So far we're very pleased with this alarm/shut-off kit. Thank you!

    Thus far VG product. hope this will prevent future floods. interfaced pretty easily with existing ice-maker and water line. Could be made made slightly heavier in construction for the money, but everything is plastic these days, As stated in the brochure has outputs for interface into home security system as well. Would not hesitate buying additional units if necessary.

    Awesome company to purchase from. Fast shipping. And, everything worked perfect
    DARRYL -- spring hill, TN   12/13/2008
    5 stars I like the piece of mind I get with having the flood stop. I started looking for some way to prevent a flood when the water line popped off the dishwasher and flood the kitchen, what a disaster!!! The flood stop was easy to install and tested well. was easy and fast, Thank you Darryl
    MICHAEL -- alexandria, VA   7/10/2008
    I needed to lengthen the cable to the sensor since the refrigerator and shutoff valve are in different rooms.
    TODD -- santa cruz, CA   4/27/2008
    Product is good, but double back tape does not work very well.
    LEROY R -- victorville, CA   11/16/2007
    not in service but installed, waiting for tenant, but there is lousy adhesive on the control unit velcro mounting. Typical China, they haven't mastered 'tacky' adhesive yet!!!!
    GARY -- williamsburg, VA   3/9/2007
    My wife and I had an icemaker hose burst last year. We have since installed a laminate hardwood floor. The result would have been catastrophic without the shutoff valve. I need to find some fittings to make it fit closer to the wall because it makes the refridgerator set out too far and I hope to have that solved soon. I am pleased with the quality of the valve.
