Onsite Pro FS1NPT Water Heater Floodstop, 1 Inch Valve

Works as expected

peace of mind

Installed the Flood Stop on the main water line in the crawl space of our vacation home. Took the plumber less than an hour to install the valve and took me about another hour to run the power and set up the control panel.Now we can leave our home and with the push of a button turn off all water to the house. It recently dropped to 20 below in a freak winter cold snap. The owners association was sendind out email warning home owners and reporting dozens of homes had suffered pipe damage and water leaks. While we were thousands of miles away, we had peace of mind that we would not come back to broken pipes and flood damage thanks to our Flood Stop.This is a great product that is elegant in its simplicity, and worth every penny.

unfortunately this product came out of box failure..twice...I returned it with a note just giving an idea for better protect the components that during transport or storage gets hits...Now the return process is excellent and not complaint about it

This was easy to install and works perfectly. Just the slightest mist of water on the sensor and the valve closes and alarm sounds. After installing a new water heater there was a tiny leak in one of the fittings on the new water heater and the flood stop turned off the water quickly preventing the floor from even becoming wet. I wish I had this device last year.

This review is a personal account of my Floodstop system in action.I have installed the 3/4-inch NPT model:  FloodStop Water Heater Auto-Shutoff Valve (FS 3/4-inch NPT) (Also, please see my detailed review on the Floodstop for washing machines ( FloodStop System for Washing Machine ) )I installed the Floodstop for my hot water heater almost four years ago. I purchased the unit and installed it just as an insurance measure just in case the heater were to ever leak. My hot water heater is installed in the attic of a two story home and any water leak from the hot water heater would cause major damage and cost to repair. For me this would mean damage to ceilings, carpet, hard word flooring, and appliances in the path of destruction. Because my hot water heater was in the attic this also meant that a water leak would likely could go unnoticed for a longer period of time thus causing the damage to be more extensive. Deciding to purchase and install the Floodstop just helped me sleep a little easier each night.So as I said ... I purchased and installed Floodstop just as a preventative measure and I never really expected to need it. Well, that was until earlier this year when my hot water heater did develop a small leak. A pinhole leak developed in the metal braided supply line where cold water comes into the hot water heater. It was a small leak that was spraying a tiny jet of water out. The water was spraying all over the top of the hot water heater and out beyond the hot water heater overflow pan directly onto the attic floor. Within a couple of minutes the water reached the floodstop sensor and tripped the Floodstop controller. Immediately the Floodstop controller turned off the supply line valve and thus stopped the infinite supply of water that would have continued saturating the attic floor. Had it not been for the Floodstop, I am sure that this leak would have gone on four hours unnoticed. It was not a major leak where gallons a water were pouring out every minute but rather a small leak that would slowly penetrate and saturate the ceiling and walls.So I'm very thankful now that I did decide to purchase and install the Floodstop system and it had certainly more than paid for itself with just this one incident. Thank you Floodstop for making a great product!Since Floodstop is a reactive system that only gets exercised when a leak occurs, it is highly recommended that you proactively test the unit from time to time. I test my system about every six months and replace the batteries at the same time. I do have mine systems plugged into AC power, but the batteries are there to serve as battery backup in the case of a power outage when a leak occurs. To test the system, I turn on the hot water tap at a sink and then go and dribble a small amount of water on the Floodstop sensor. The water on the sensor should trip the Floodstop controller and shut off the supply valve. If everything worked properly the Floodstop should be beeping and the water should have stopped at the sink. Its also a good idea when testing the system and replacing batteries to also clean the sensor pad. I usually just wipe it down with a damp cloth or paper towel and then gently pat it dry off with a soft cloth. Avoid scrubbing the sensor pad as you don't want to damage the traces on the circuit board.... Taking it one step further ...If you would like to get notified via email and/or text message when a leak is detected, please see my blog. I have written a blog article on how to use a Twine device to send you email/text alerts when the Floodstop detects a leak.Please view my Amazon profile for a link to the website.
