## Description

Review: Quality materials/product - Needed a replacement due to living in a high rise condo. Works as described and easy to install.
Review: Provides great peace of mind - Great product. Like many others who have bought this item, we have our washing machine on the top floor of our house. We have an older machine that sounds like a SpaceX rocket about to take off every time we do laundry, so it always worried me that I might one day come home to see my house flooded and recreating that scene in Jumanji, with water flowing down the stairs and giant spiders attempting to kill a ten year old boy. I don't even have a son, which makes it that much more worrisome! In all seriousness, this product works well. Super easy to install. The pad is so sensitive that when I touched it with my bare hands, the moisture alone from my fingers set off the alarm and shut off the pipes. I was also profusely sweating at the time thinking about Jumanji, but that's beside the point. The alarm sounds intermittently until you manually re-open the pipes via the control panel, which is good to know in case it ever shuts off while we're away. Also, it has a battery backup system that runs off 4 AA batteries, which is great in case the power goes out. One thing to note: our washer/dryer area only had one plug (not a standard double outlet), so we had to get a multi-outlet adapter before installing. Just wanted to point that out because it was a pain to have to pull out the machines and set everything up, only to realize we were missing something crucial. Just wanted to give a heads up for everyone to avoid this problem, in case you were hiring a plumber or something to install it for you. Overall, excellent product. I made a note to check the system every 3 months or so and test the strips and mechanism. If I ever run into any issues, I'll update this review accordingly.

**Q: How long will it run on batteries (assuming it doesn't detect water and shut the valve and sound the warning tone)?**
A: ·         If there is no nearby 110V outlet and the low-voltage transformer that comes with each FS kit will not be used to power the FS system... then the 4 AA batteries within the controller will typically power the FloodStop for 1 year. When batteries get low, it will initiate a beep every minute. ·         If the FloodStop is being powered by its own low-voltage transformer and has 4 AA batteries inside the controller... the batteries will stay dormant/unused unless there is a power outage... at which time the batteries will typically power the FloodStop for 1 year. When batteries get low, it will initiate a beep every minute.

**Q: What it the difference between FS3/4H-90 v4 and FS3/4H-90? The v4 product is more expensive. What is added for the additional cost?**
A: The v4 version is the newest version of the Floodstop devices.  This version of the unit has a new controller, and the valve is now lead free.

**Q: Will the washer become damaged if it tries to function with the water off?**
A: Most washers will stop trying to function when no water is present. My machine will produce an error code, which is reset by turning machine off and on. So, no, most machines will not get damaged. The solenoid that opens valve to let water in will open, and after a while the machine will sense there is no water, and will shut down.

### ⭐⭐⭐⭐⭐ Sturdy, Works well - Great price for peace of mind
*by D***D on March 12, 2013*

I just installed this this weekend, and I must say I am very impressed. As some mentioned, the module itself is light, which some people have associated with cheaply made. At the end of the day, the module itself is a circuit board with buttons and needs room to hold the 4 C batteries. The valves themselves do have a plastic cover, but the valve and pipe feel solid and work extremely well. I probably had the whole thing installed within 30 minutes. (It doesn't come with plumbers' tape, so make sure you have some on hand.) It works spectacularly well. The water sensor is very sensitive with numerous trip points to cover a lot of ground. It can be daisy-chained with additional sensors if you like. The slightest bit of water trips the sensor, and the device immediately springs into action. The valves are close, and the alarm sounds. It will continue to beep periodically so that if you weren't home to hear the alarm go off, you'll know when you walk in. What I love is that the manufacturer also thought about expansion. The Floodstop has both normally open and normally closed outputs that can be used to signal other devices on alarm. With this I was able to tie it in with my home automation system so that when it detects water, it not only closes the valve shutting off the water supply, but signals my home automation system so it can kill power to the washer & dryer, as well as text me. Very well built, and highly recommended. My plumber saw the unit, and even he was impressed. I think he'll be ordering some to install for his other clients!
