More Information About This FloodStop System

Don't be the victim of washing machine identity theft. This can happen when your washing machine changes its identity and turns into a water terrorist by no longer washing your clothes but instead deploys water onto your floor, ultimately draining your water pipes and your checking account. Help prevent this from happening to you. Ruptured hoses, cracked fittings, or even internal failures like switches, clamps, or pumps could already be planning their devious attack strategies even as you read this. You know they won't usually strike when you're home. Oh no, they will wait until you are away for the weekend or on vacation, for that element of surprise attack, when it can hurt you the most, waiting to dump gallons of water that could flow undetected for hours or possibly days. Don't let your washing machine take you to the cleaners!

Installing a FloodStop system will give you an edge over this type of assault and help diffuse an ugly situation by detecting water on the floor and immediately turning off the water supply to the washing machine and sounding an alarm to let you know of this security breach and that it has stopped the insanity before it had a chance to escalate. The other household fixtures and appliances will still be fully operational and not even aware of this incident.

The FloodStop includes additional output contacts, which can be used to establish instant communication to an Auto-Dialer, or X10 Home Automation system or even your Home Alarm system to contact you first, in case you are out of town, or let your loved ones also know about this attempt to disrupt your busy lifestyle.

If your washing machine is set inside a pan, you may want to consider using 2 sensors and placing one outside the pan and the other inside the pan. Additional sensors can also be used for even quicker detection and to increase your area of protection.

Once you or your reinforcements have subdued the uprising and detained and/or replaced all of the rebellious components, simply wipe dry the sensors, and press the green "open" button on the control unit to reactivate your scouting party, and secure your perimeter.

FloodStops for washing machines have a 1-Year Manufacturer's Warranty and are available in two styles, the straight outlet #FS 3/4-H for hose bibbs facing downwards or the 90 degree outlet #FS 3/4-H90 for hose bibbs facing out of a wall or wall box. Both kits include two motorized ball valves with 3/4" female swivel hose thread unions to easily attach to your existing hose bibb valves.

The Control Unit includes a 120 volt AC transformer with a 30" cord to each valve and has optional battery backup (4 each "AA" size batteries not included). Or, the Control Unit can operate with 4 each "AA" size batteries (not included) as the main power source if an electrical outlet is not available, but battery replacement is recommended every year or when the low battery alert indicator is activated.

Very easy to install, these FloodStop Kits should take less than 15 minutes from start to finish. If it takes you longer, we promise not to tell anyone!

We suggest you please make certain to follow all of the manufacturers directions and maintenance steps (included in your shipment) to help ensure you are protected from your washing machine.

How these washing machine FloodStops work in 5 easy steps:
  1. One FloodStop valve is screwed onto the hot and one onto the cold water hose bibbs
  2. Water/leak sensor is placed on the floor behind the washing machine
  3. Valves stay open until water loss is detected
  4. Water on sensor immediately closes FloodStop valves and sounds alarm
  5. Valves stay closed until problem is fixed or repaired and system is reset



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. Yes they can; whether it's a small leak or large flood, FloodStops shut off the water at the appliance. They can help protect against broken lines, bursting lines and failure of internal components of your plumbing fixture.

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 9-foot-long 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. "Can these systems be used in lead-free applications?"
A. All FloodStop models have been certified as lead free. Please note the FS 3/4-H and FS 3/4-H90-V4 are not required to be lead free since they are for washing machines, but these same valves can be utilized in potable water applications.

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 visit our LEAD FREE Plumbing Information page.

Q. "If I purchase the WaterWatcher system, why would I need to purchase the FloodStop system?"
A. The WaterWatcher is designed to turn off the electrical power to the appliance, but will not turn off the water supply if a hose was to break. The FloodStop will turn off the water supply but not the electrical power.
