The Watts IntelliFlow® Automatic Washing Machine Shutoff Valve uses a state-of-the-art electronic control device that senses the washing machine current flow. When the washing machine is turned on, the controls detect the current flow to the washer, opening both hot and cold water inlet valves to allow water to flow to the washing machine. When the washing machine completes the full cycle the device senses the lack of current and closes the water inlet valves. These valves remain closed until the machine is used again. The IntelliFlow®'s automatic operation and floor mounted leak sensor
protect against catastrophic water damage should a washing
machine inlet hose burst while the machine is in use or unattended.

I installed this unit in our 2nd floor laundry room after reading earlier reviews that were positive but with some warniing of early failures. It seems to be the best available on the market from what 've seen in my research, although it could still use some improvement IMO. Easy install if you have some plumbing skills and an electrical receptacle nearby - I had to wire one but that was minor for me in a major remodel situation.So far, so good after several months in a 2nd floor laundry room that I installed a number of years ago but never finished to my (and my wife's) satisfaction. Beats the manual single lever that I put in at first when that was all that was available on the market that I could find. However you're now relying on an electronic rather than a manual shutoff valve for everyday shutoffs - that's the tradeoff for having an electronic leak detector as well which comes with this unit. You can always (and should) add in line shutoff valves before the unit for work on this shutoff and trips awat from home for extended periods. You can't be too careful in safeguarding against upper story major water leaks. Read a few horror stories on line if you don't believe me.Add upgraded burstproof hoses and a dedicated floor pan with drain as I did and you've done about all you can do to prevent nuisance and catastrophic floods above finished areas IMO. In my case above a newly and expensively remodeled kitchen and bath on the 1st floor. You can always go back to a basement laundry if you don't trust that setup; tradeoff: two flights of stairs both up and down for every basket of laundry washed and dried as we did when we first moved to this home. No, thanks! Even a two story laundry chute doesn't get laundry back to its main point of origin for most households: the floor with the most bedrooms' in our case the 2nd.Improvements that I spoke of: mainly the fact that the manufacturer seems to have adapted an existing molded plastic box by another maker to fit their valve and actuator assembly. Both are good to excellent in their own right, but the box jusrt doesn't fit the valve the way it should in my opinion. Nothing really wrong, just not a really secure and flush fit to the back (wall side) of the box - I had to shim it if I didn't want it secured only by the brass valve locknuts at the base of the unit, and I didn't feel that was secure enough for my standards. A bit of a leak basin at the base of the unit as I had in previously used units wouldn't hurt either. The longevity issues mentioned by previous reviewers concerns me as well.Maybe I'm a bit fussy about these things, but I've found in decades in the building trades that doing it right the first time is cheap insurance, especially when it comes to preventing possible plumbing leaks. My $0.02 for what it's worth.

Valve failed after 3 years

I bought this for a second floor washing machine. After 3 years the solenoid on the cold side has failed-so no cold water passes through to washer. There is no sediment-it simply failed. For this kind of money I would expect it to be reliable for many more years than 3.

Excelent protection for washing machine
By The Art of Fine Plumbing
from San Francisco, CA
The watts intelli flow keeps the water off to the washing machine untill you are ready to use the machine. The wm plugs into the inteliflo, so when the machine is turned on, the intelli flo opens the water. Once machine is finished, the Intelli flo turns the water off. Depending on type of W. M. used, you may have a 220 WM, they also have an intelli timer that plugs into the intelli flow instaed of the wm. When you use your wm, just hit the button and the intelli flo opens for 2 hrs. The unit also has a water sencer to set in a pan under the WM.I install a stainless steel pan under the washing machine. The slightest bit of water in the pan and the intelli flo turns off. These are great in multi unit high rise buildings or second floor and above units or homes.
Installed and turned on , it worked. Need to partially disassemble to get wrench on top nut to tighten supply tubes. Didn't have washer hooked up so used hairdryer to test, turn on hairdryer on came water turned off and water stopped . What more can I say.
Prevent water damage
from New Hampshire
I first saw this on TV (This Old House). I installed one and it lasted 11 years before the electronics failed. I bought another as a replacement. I think it is a great product.

Replaced manual shut-off valve with this. Requires some plumbing skills (may need licensed plumber). Had 'slow' drip behind washer. Rotted out baseboard, molded sheet rock and some sub floor damage before I noticed it. Only about a 2 X 2 foot area but cost almost $700 to repair. Installed auto shut-off valve and used 'U' bracket to mount leak sensor to bottom edge of new base board. Spilled some water on the floor to test it and as soon as it ran over the the sensor CLICK the water to the washer shut off! No more water damaged walls for me! Other 'plus' are no pressure in water hoses unless the washing machine is on and if a hose blows while the washer is in use the leak sensor will protect you there.

I have been installing the watts intelliflow for several years now in High rise condominiums. With all the valves I have installed, I only have had one misbehave Pex Supply sent a replacement right away. The valves Pex stocks, have a special wall casing included which are made for the Watts Intelleflow. Not like the valve only you get from the plumbing supply houses.
Excellent solution to possible disaster!
from Manassas, VA
We currently use this product in our renovated second floor master bathroom. The bathroom was designed to include a washer and dryer flat tiled floor space with a separate floor drain for the new washer. While the floor drain was considered necessary, it was not sufficient, we felt, to sustain a hose break or a wash tub failure. The Watts A2C-WB shutoff valve and leak detector solved this problem. We also saw the unit installed by "Richard" in a "This Old House" episode on TV. This is our second Watts A2C-WB unit and it will be installed to support our first floor laundry room washer unit. The first unit was installed by a professional plumber as will the second unit. The units look good, perform well and allow us a peace of mind we would not have without them. Literally, we cannot afford to have a washing machine water disaster on the second floor of our newly renovated house.
The best flood insurance you can get!
from Southwest Florida
I am now constructing the third home in which I have installed the IntelliFlow shutoff valve. The valve accomplishes two things . . . it prevents your home from being flooded because of a leaking/ruptured hose (through the leak sensor) by shutting the water completely off, and . . . it automatically turns on/off the hot and cold water supplies each time you turn your washing machine on/off. There's nothing you have to remember to ensure your home is protected. The only problem I had was that after many years, one of the valves failed, and it was a real bear to replace because the supply pipes in my house were misaligned. Had it not been for that, it would have been an easy task for any do-it-yourselfer.
