FloodStop 1/4" Flood Protection System

For refrigerators, icemakers or water dispensers


There are many reasons to install a leak detection alarm, the biggest being that it is an inexpensive way to protect your home from water damage such as water staining, sub-floor deterioration, mold, etc. Imagine coming home from a vacation to find that your refrigerator has sunken through the floor due to long hidden water leak unseen underneath it! Water can seep through the smallest of cracks in the linoleum or other flooring, and once it has a path it will continue to follow it, causing very expensive damage that could have been easily avoided with a FloodStop system.

FloodStop System for Refrigerators, Icemakers or Water Dispensers

FloodStop FS-14-C-V4

FloodStop (FS 1/4-C-V-4) Components and Specifications:
  • One Motorized Ball Valve (1/4 inch Compression Fitting
  • One Control Unit with Battery Backup and 30" cord to the valve
  • One Water/Leak Sensor with 7' cord
  • One Transformer: 120 Volt AC Input - 9 Volt DC Output with 30" cord
  • Power Option: Can use 4 each "AA" Batteries as Primary Power Source (batteries not included) batteries should be installed for battery back-up when used with the 120 volt transformer
  • One 6" Output Contact Wire

Refrigerator icemakers use a valve that opens and closes very quickly. The quick opening of the valve is a good feature, but the quick closing of the valve can cause problems. When any type of water valve is closed quickly it can cause water hammer in the water line by literally creating waves in the water pipes as flowing water stops and flows back against the oncoming flow causing a pressure spike and the pipes to vibrate. Vibrations can cause pipes to loosen or eventually cause older piping to crack and unexpectedly rupture. Water-line breaks can also develop from movement or accidental bumping of the pipes, which naturally can occur with normal refrigeration use. A small leak can quickly turn into a major problem if left undetected.

More Information About This FloodStop System

These FloodStops were developed for use with refrigerators, icemakers, water dispensers, or anything that uses water and has a 1/4" compression connection. This system can help you detect water where you may not be able to readily see a leak, like behind the refrigerator, inside or under a cabinet, in a closet or other places not normally easily accessed or visibly seen. When the sensor detects water it sends a signal to the control unit which automatically shuts off the water supply to the refrigerator (or icemaker or water dispenser), and immediately sounds an alarm to let you know about it. All of your other household fixtures and appliances will remain operational since only the refrigerator (or icemaker or water dispenser) will be shut off.

This FloodStop system includes additional output contacts, which can be used to electronically communicate to an existing auto-dialer, home automation system or even your home alarm system to make sure you are aware of the problem if you are out of town.

To reactivate and reset the system after the problem has been repaired, simply wipe the sensors dry and press the green "open" button on the control unit.

This system is very easy to install, taking most users less than 15 minutes to install.

Safe for potable water applications.

1-Year Manufacturer's Warranty.

FloodStop FS 1/4-C (V-4) Components and Dimensions:

  • One Motorized Ball Valve (1/4 inch Compression Fitting - approx. 2-3/4"(L) x 3"(H) x 1-3/4"(W)
  • One Control Unit with Battery Backup and 30" cord to the valve - 4-3/4"(L) x 4-3/4"(H) x 1"(W)
  • One Water/Leak Sensor with 7' cord - 7-1/2"(L) x 1-1/4"(W) x 1/8"(H)
  • One Transformer: 120 Volt AC Input - 9 Volt DC Output with 30" cord
  • Power Option: Can use 4 each "AA" Batteries as Primary Power Source (batteries not included) - batteries should be installed for battery back-up when used with the 120 volt transformer
  • One 6" Output Contact Wire

How FloodStop FS 1/4-C (V-4) Works:

  1. The FloodStop valve is connected to the angle stop and the supply line
  2. Water leak sensor is placed at the base of the appliance (ice maker/refrigerator, water filter, etc.)
  3. Valve stays open until water leakage is detected
  4. Water contact with sensor closes FloodStop valve and sounds alarm
  5. Valve stays closed until problem is repaired and system is reset

Always make sure that you take the precaution of following the manufacturer recommended, required regular maintenance and inspections (included in your FloodStop package) to ensure that you are protected.

Note: FloodStops can help prevent flooding, but do not provide 100% guaranteed flood protection. We cannot be held liable for any damages that may occur when flood stops are installed. Always refer to the owner's manual and perform maintenance per the manufacturer's recommendations.

Frequently Asked Questions

Q. "How does it work?"
A. Simple! You'll install a FloodStop motorized ball valve(s) upstream of each supply line and place our water sensor on the floor behind the unit that needs detection. If water leaks due to a broken line or the failure of ANY internal component of your plumbing fixture, the control unit tells the motorized ball valve(s) to shut off the water and sound an alarm.

Q. "So these systems can help prevent leaks or flooding?"
A. They really can't help prevent leaks. They can help prevent flooding by shutting off the water if a leak happens.

Q. "If there is no electricity running to the valve (either because they haven't been hooked up or the sensor has touched water), are the valves normally open or closed?"
A. In their normal position, the FloodStop valves are open and will allow water to pass through; once water touches their sensor, the motorized ball valve is tripped and the valves are closed. The valve(s) will remain closed until the sensors are dried and the reset "Open" button is pressed. The Controller has a battery port for 4 X AA size batteries, which will serve as a battery backup in case of a power outage. The same batteries will serve as the primary power source if a nearby electrical outlet is not available (battery life 1 year).

Q. "Does the FloodStop system shut off water to the whole house?"
A. No, this is a point of use product; it only shuts the water off at the source of the leak. Why shut off the water to your whole house if the cause of the problem is just at the washing machine, for instance? Whole house systems are much more expensive and usually require a plumber to install.

Q. "What should I do after the system has detected a leak?"
A. If a leak has occurred, turn the manual valve(s) to the off position, investigate and repair/stop the leak, dry the sensor, and reset the controller by pressing the "Open" button.

Q. "Are FloodStop systems difficult to install?"
A. No, if you can install a garden hose, you can install FloodStop. Installation takes 5 to 10 minutes, and your home will be protected against many sources of water damage.

Q. "Why would I need to use the transformer extension wire?"
A. Unlike the washing machine and the icemaker, the water heater is not always located next to an electrical outlet, and so you may need to use the approximate 7-foot-long (86") low-voltage extension wire.

Q. "Why would I need an additional sensor?"
A. You can increase your area of protection by adding extra sensors near the fixtures or appliances you have selected to protect. If you want more protection for your washing machine FloodStop valves you can add another sensor behind your dryer or laundry tray/sink or maybe a low spot on the floor where water tends to puddle. Or if the water heater FloodStop is purchased then additional sensors can also be placed in your water heater's drain pan, as well as on the floor nearby (in case a leak sprays outside the pan). Or if you want a quicker detection for your icemaker FloodStop, you may choose to install a sensor under your icemaker valve, another behind the refrigerator and a third near your icemaker's filter (if you have one).

Q. "What about braided hoses, aren't they burst proof?"
A. You should use braided hoses whenever you can (especially on your washing machine), and take every precaution to avoid water damage, but hoses are not the only source of flooding. And, braided hoses are not burst proof, but only burst resistant. There are a wide variety of clamps, valves, pumps, drains, etc. inside many fixtures that can fail. (FloodStop was designed after the inventor suffered a home flood due to a switch failure that did not tell his washing machine when to stop filling with water. Water continued to run into the washer and flooded the house for 3 hours before it was discovered).

Q. "I'm hearing a lot about lead-free these days. What does that have to do with plumbing products and how does the new lead-free legislation affect me?"
A. Basically, the laws implemented Jan. 1st, 2014 require plumbing products that come in contact with drinking water to be "essentially lead free" (less than 0.25% weighted average). For further information about how the law determines what is "lead free", rules regarding which plumbing products must be "lead free", and who these laws will affect, please click here.
