Welcome To Hawkeyed Water Defense! Your One Stop Shop For Leak & Flood Prevention Solutions
Water damage is one of the most common and costly types of property damage, accounting for billions of dollars in losses each year. Hawkeyed Water Defense offers a variety of easy-to-install and affordable water leak shutoff and flood prevention technologies to help you protect your home from water damage.
Our main products include the Water Block, E-WATERBLOCK, Water Block kits for 1/4", 3/8", and 1/2" water supply lines, and the Flood Prevention Hose. We also offer some specialty fittings.
Our Water Block products are automatic shutoff valves that are triggered by a sudden increase in water flow. This means that if a leak or flood occurs, the valve will automatically shut off the water supply, preventing further damage.
Our Flood Prevention Hose is a unique product that can be used to prevent flooding from hoses and other water sources. The hose is equipped with a sensor that detects water flow, and it will automatically shut off the valve if it detects a leak or flood.

Let customers speak for us
from 14 reviewsSimple and novel. We live in a drought restricted area. This is a great comfort to have

This extended my washer connections just enough to hook the hoses to easy. Solid, well made.

So first off I am a real person...or is that what a bot would say? I am always dubious with the sellers site reviews, but this product is exactly as described.
I have common issues with the kids upstairs toilet overflowing and running, which is a major issue for an upstairs toilet with wood flooring right below it....
Anyways, installed the water block/ reset tool and problem solved. Already saved me once, kid flushed, walked away, toilet overflowed a little and then the water block shut it off.
I had to fiddle with the volume, and even tested it with a bucket a few times to "get it right". My advise is give it a bit more volume then you really need. I had it set a bit to close to "actual" requirements and it tripped a few times until I gave it a little more wiggle room. While this means you might get a little overflow potentially, my 2c for me this is to stop major flood issues.
Great job!
Feedback to Hawkeyed: I would be to just include the reset tool as part of a more streamlined toilet kit product. While it works, the tool adds the the length overall and is sometimes hard to push down to reset. No one using this for most applications wants to take the device apart to reset.
If you made one purpose built, perhaps it could be designed to be more streamlined/compact and a bit easier to press for kids? That being said I am pleasantly surprised that is works as well as it does, and the fit and finish is top notch.
Thanks!

I have a toilet where the flapper doesn't seat properly sometimes. I did not know it was a very frequent sometimes ! Installed it 1 week ago and has saved us 3 times so far ! Great product.

Great service, fast shipping, immediate reply to emails, and friendly team!! Would order from this company again when I need to.

Installation instructions become clear once the product was in-hand. Was trying to decide if horizontal or vertical install would work and with or without the reset device. Finally ordered horizontal layout with reset device and was able to install behind toilet parallel to wall so it is not noticeable from above. Shuts off water flow and resets as described. Works better than anticipated.

Unfortunately, our house had water damage from a hung clogged toilet than overflowed for less than 30mins. After dealing with this incident I decided it was time to research to figure out what options were on the market to prevent this from happening again. Thankfully I landed on Hawkeye Water Defense. After purchasing a few water blocks for our toilets I decided to also protect our dishwasher, refrigerator, and washing machine. I’ve been impressed with their products build quality, functionality, and price. It’s a no-brainer to install in your home for the extra peace of mind!

We live in rural VT with well water. If the toilet accidentally runs (flapper issue) it wreaks havoc on our water system. Our house is 150 years old, well maintained but no major renovations. We have plenty to keep us busy and the water block-toilet shutoff just made our lives easier. We are tight on space in the bathroom and the horizontal design was perfect. It is easy to assemble, it works beautiful and there are plenty of online support materials available. I’m on the site now because I’m buying a 2nd unit for our other bathroom. I wish all products were as well designed & affordable as the water block-toilet shutoff. Well done!

Just received and installed the Water Block. We installed it, tested it and are very impressed. I think will stand the test of time.

Speedy delivery, nicely packaged. Waiting on a plumber to install.
Thank you!

Works as intended. If toilet runs, the water shuts off 45 seconds after the time it would take to fill the tank.
