FloodStop 3/8" Flood Protection System

For kitchen and bathroom faucets

Help protect your home, family (and wallet!) from costly, potentially dangerous damage with a FloodStop System for your bathroom and kitchen. Bathroom and kitchen faucets are connected to hot and cold water supplies, and these connections can, over time, become worn out and leak. Once a supply starts to leak, because it is not in plain site, the leaking water can cause hidden damage such as weakened floors and mold growth, which may go undetected until the damage is obvious. Save money and gain peace of mind with this simple, low-cost method of protection.

Leaks in plumbing often start off as small drips and go unnoticed until gallons of water have created enough significant damage to draw your attention to this disappointing discovery. The damage often goes undetected until the floor is visually damp or your hardwood floor is buckled or the smell of mildew is present, your cat is soaked and meowing madly at you, at which time you realize the damage and cost to repair or replace is going to be extensive, not to mention the cat's going to need therapy. Easily installed within 15 minutes this system can help prevent you from unnecessary anguish. As soon as water touches the water detection sensor, strategically placed by you, the FloodStop (FS 3/8-CD) automatically shuts off the water supply immediately to both hot and cold supply lines you have chosen to monitor and sounds an alarm. You may have a bathroom faucet, kitchen faucet, utility sink, bar sink, or other water supply valves that could put the most valued household items you have at risk if for any reason the supply tubing were to fail. This system can help protect you.

More Information About This FloodStop System

Designed for 3/8" compression connections, this FloodStop system will fit most kitchen and bathroom faucets. As soon as water touches the water detection sensor, the FloodStop (FS 3/8-CD) automatically and immediately shuts off the water supply to both hot and cold supply lines you have chosen to monitor and sounds an alarm to alert you.

Once the motorized ball valve is installed simply plug in the AC Adaptor/Transformer (120 Volt AC Input - 9 Volt DC Output transformer with 6 ft. cord) to the nearest electrical outlet. Batteries should be installed for battery back-up when 120 volt transformer is used or if no electrical power is nearby it can be powered with 4 each "AA" Batteries as the primary power source. Batteries are not included and you must remember to change the batteries at least once a year if not a little sooner.

One 6" output contact wire is included with the control unit to allow the system to be connected to an auto-Dialer, or X10 Home Automation system or even your home Alarm system to make you aware of the problem if you are out of town.

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

1-Year Manufacturer's Warranty.

Use anywhere potable drinking water products are required.

How FloodStop (FS 3/8-CD) Works:
  1. The FloodStop valves are connected to the angle stops and supply lines
  2. Water leak sensor is placed at the base of the fixture (sink - laundry basin - tub - etc.)
  3. Valve stays open until water leak is detected
  4. Water contact on sensor closes FloodStop valve and sounds alarm
  5. Valve stays closed until problem is attended to and system is reset

Always make sure that you take the precaution of following the (included in your FloodStop package) regular maintenance and inspections required 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 view our page.
