Soon after, I began building Water Hero to protect homes and businesses from these costly & damaging leaks.

Customers Love Water Hero

  Try it, the peace of mind is well worth the small investment

“Four houses in my neighborhood flooded this past year because of cracks in toilet supply lines.  One homeowner was out of his home for 3 months while repairs totaling over $200K were completed.   I researched all available options and finally decided to try Water Hero because it provided the Most Flexibility, Most Information and the Most Protection.I don’t recommend many products but have recommended Water Hero to a number of people already. Try it, the peace of mind is well worth the small investment.”

  A toilet valve broke while I was sleeping – Water Hero detected the problem and shut off water before significant damage

“My house has had three floods over the past decade. All of the floods occurred when I was away from home, leaving me with thousands of dollars in damage. I bought the Water Hero detection system after reading about it online. It has exceeded all of my expectations! The Water Hero was easily installed by my plumber, the online dashboard is very intuitive and the e-mail/text alerts are great. Recently a toilet valve broke while I was sleeping and the Water Hero detected the problem and shut off the water before any significant damage was caused. The Water Hero provides me with peace of mind and I recommend it to all! Thanks for everything Water Hero!”

  Enter Water Hero: the affordable whole house water shut-off device that offers real protection

“I had not realized that up to 1/3 of all insurance claims are water damage related. I immediately started to research water shutoff devices but found that most provided only limited protection because they rely on area sensors and others were too expensive and offered no remote internet control. Enter Water Hero: The affordable whole house water shutoff device that offers real protection and peace of mind. It was easy for my plumber to install and it has been easy for me to use. Water Hero offers simple customizable settings with easy internet control that allows you to see how much water you are using. Now that I have my Water Hero monitoring my home, I sleep better at night.”

Frequently Asked Questions

How much does it cost to install Water Hero?

Depending on your location, installation typically costs between $250 to $500.  Plumbing installation typically takes approximately one hour.  Please connect your Water Hero electronics to your local network BEFORE your plumber comes out to plumb your unit in.  This will save time and money, and help you insure you have an adequate WiFi  signal strength at your point of install.

How reliable Is Water Hero? What is the warranty?

 We were one of the first companies to launch “smart” next generation leak detection in 2016.  We’ve developed, tested and continue to improve Water Hero over the last six years. Leading the charge is a team of seasoned software developers, electrical engineers and quality assurance engineers with multiple patents.  At Water Hero, we prioritize functionality to ensure that your unit is operating to the specifications that you set.   To back up our product, we offer a 30 Day Satisfaction Guarantee and one year hardware warranty.

How does Water Hero work with an irrigation system?
We recommend that you install Water Hero after your irrigation system splits off from your pipe – your plumber can help with that.  But, if you can’t install at that location, our team will work with you to develop the appropriate settings to ensure that everything is operating for your home in particular.
Does Water Hero work if I have well water?
Yes, Water Hero is installed on multiple well systems.  We recommend that you cut the Water Hero in after your pressure tank and well pump.
Is Water Hero Installed vertically or horizontally?

Water Hero can be installed vertically or horizontally, with proper support; whatever orientation is most convenient for your particular installation. 

Can Water Hero be installed outdoors?

Water Hero can only be installed outside, above ground only, in climates that are above freezing year-round, with our optional outdoor install kit.  This kit includes a sealed sensor cap that mounts on our smart water meter and an enclosure box to protect our main controller unit from water such as rain or lawn irrigation.

IMPORTANT NOTE: these units are not freeze proof, and will break if subjected to freezing temperatures, voiding your warranty.


What size pipe can Water Hero be installed on?

Water Hero offers units for 2″, 1.5″, 1” and ¾” pipe sizes.  Please contact us for details on our 1.5″ and 2″ units.
