Stop Flood Damage With Automatic Shut-Off Valves

Automatic shut-off valves

What are some of the things people associate with flooding? Rain? Basements? Sump Pumps? What if we told you that basement flooding was not the most common cause of flood damage in a home. Would that be a surprise? It certainly surprised us, Safeco Insurance says “on average, almost ¾ of our home water loss claims each year are caused by an appliance people used everyday” i.e. washing machine, dishwasher or water heater. GuideOne Insurance drives the point home by saying “The most common cause of water damage is not rain or flooding, but burst hoses on washing machines, refrigerator icemakers, and other appliances.” With that being said there is very little advertising about the product that can take care of the problem.

Automatic Water Shut Off Valves Aren’t Just for Commercial Plumbing Anymore

Floodstop valves are automatic motorized valves that sense the presence of water and automatically shut off. The valves plug into a normal outlet for primary power or they can use 4 C type batteries if an outlet is unavailable. Each valve has outputs that can connect to the alarm, home automation or an auto dialer so you’re covered if a valve is actuated. The valve even has a self cycling feature that actuates the valve once per month to clean off sediment or build-up. Currently Floodstop has valves in ¼”, ⅜”, ½”, ¾”, 1” and 11/4” for installation on water heaters and water treatment units, washing machines, dishwashers, point of use filters and toilets, kitchen sinks and icemakers.

The first is meant to be installed on a water heater and as you can see it has a threaded connection.

In the illustration to the right you can see how a typical install would be made. The Floodstop valve is installed on the incoming cold water, the control unit is plugged in or mounted near the heater and finally the sensor is placed on the floor near the heater.

The next valve pictured below is a 3/4″ connection but accommodates compression or sweat connections.

The Floodstop’s 1″ & 11/4″ valve is meant for a large water heater or water treatment equipment i.e. water softener, iron tank or whole house water filter and the second picture is the 3/4″ Floodstop valve for use on washing machine.

There are other    Floodstop valves for ice makers and refrigerator filters and they are all very similar in function as the valves you see above. However there is one valve called the H2Orb used on toilets that is a real innovation. It mounts on the shut off valve serving the toilet and it comes with two wireless sensors, one for the inside of the tank that measures the water level inside and the other mounts in the bowl to detect a potential overflow.automatic shut-off valves

  1. First off I would like to say excellent blog! I had a quick question that I’d like to ask if you do not mind.
    I was interested to know how you center yourself and clear your head prior to writing.
    I’ve had difficulty clearing my thoughts in getting my ideas out.
    I do take pleasure in writing but it just seems like the
    first 10 to 15 minutes are usually wasted just trying
    to figure out how to begin. Any ideas or tips?

    1. I usually take the first 10 or 15 minutes writing a loose outline. I don’t care where it goes, I just worry about what info I want to get out. Then I put the content in an order that makes sense. At that point the article takes on a life of it’s own. I do that for any subject in any niche.
