FloodStop Washing Machine Leak Detector Kit, 3/4" Straight

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.

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!

Seems well made and works when tested. Easy to install (it better be since no directions). Directions should have been included for some less obvious things like what are those 4 white plastic plugs (hint they go on sensor I guess if you have a damp concrete floor), how long do batteries last and is there a low battery indicator, what’s the pigtail for (seems like for adding additional sensors but I think additional sensors come with the wire so not certain why it’s included), etc.Also the wires were too short. My valves are behind stackables and not reachable so I wanted to put the controller on the side wall that’s about 6” from side of units. It reached to about halfway the depth of the units whereas I would have preferred them towards the front. Way too short to give you options or to go around obstacles like a shelf or pipes and you really want to route the wires in a safe path tight against a wall.Either way I’m 100% certain it will work better than the Watts Intelliflow which used to be a decent product but the last few years has junk.

This is a fantastic addition to laundry faucets. Having had a washing machine filler hose leak many years ago I am happy to have this device. It also cuts my insurance rates because of the automatic shutoff if it detects water.

This is the system you want to get. The valves are solid brass, and basically a quarter-turn tap with a motor bolted on (not a solenoid as most valves). This is important because they close quite slowly (~2 seconds), enough so a water hammer arrestor isn’t needed specifically for them (water hammer arresters should be as close to the washing machine as possible; I put mine directly on the back of the washer). I tested it and didn’t get any ‘clang’ in the pipes when FloodStop closed, with the machine pulling water.You can add additional water detector strips and daisy chain them if you want to monitor several areas at once, and you can also connect a relay (e.g. Furman), that will automatically disconnect the washer from the power supply. The relay is clunky so I didn’t bother.I think it’s a little on the pricey side for what it is honestly (the valves look well-engineered, but the electronic module looks a little toylike and cheap; it’s not an eyesore, but it’s a bit of a missed opportunity to make the purchase feel worth the price, I think). I would have been comfortable with a $50-150 range as a price.But there is nothing else that comes close (everything else I look at looked gimmicky or clunky), and clearly this was well thought-out engineering-wise. So fine, take my money. And yes, it’s always going to be cheaper than a flood. Overall, I couldn’t be happier with my purchase. We have a washer on the second floor, and that potential risk was flagged during the inspection. Took all of 5mn to install for peace of mind. I am also going to replace my water hoses.

Nothing like closing the barn door after the horses got out! I found this product after the hookup hose for my washing machine in our main floor laundry room ruptured. Yup! One hell of a mess including the ceilings in the basement. Over $20,000 in damage. Although this product is expensive it only has to prevent what happened to me to more than pay for itself. I highly recommend it and also changing your hook up hoses to the washing machine every 5 years. 👍
