  • Consider this, you are at work, on vacation or anywhere other than your home and the water pipe in your kitchen bursts or the valve under your sink fails and starts leaking everywhere....what are you going to be able to do? Nothing! You will come home and find your cabinets, wood flooring and carpet damaged, not to mention what happens to your drywall when it gets wet. The expensive removal and repairs will run into the thousands of dollars, and don't forget about the time involved to fix everything. With a Smarthome SELECT Electronic Water Shutoff Valve you can change all of that.

    The Water Shutoff Valve is designed residential and light commercial use, primarily for integration with a home security system such as Elk or a home automation systems such as Insteon. As an example, you can combine the Water Shutoff Valve with a Power Supply, Insteon I/O Linc Low Voltage / Contact Closure Interface and a Insteon Water Leak Sensor. When the leak sensor detects water, it can trigger the I/O Linc to automatically activate and instantly close the valve to prevent any further water leakage and damage. By adding multiple sensors, you can monitor leaks throughout your home and immediately shut off the main water supply should water be detected.

    If you have a vacation home or property where you might want to remotely turn the main water supply on and off, add an Insteon Hub to the scenario as described above and you can remotely control the valve from your smartphone or tablet via the Insteon for Hub app.

    Note Regarding Lead-Free Certification for use in Potable Water Applications

    There is no mandatory federal requirement for product testing or third-party certification under the Safe Drinking Water Act; however, some entities may require certification. Many states have laws pertaining to the percentage of lead content detected in water passing over a wetted surface for products used in potable water applications. California is one of the entities, as stated above, that is currently the only state that has a Bill requiring certification. It should be noted however, that this product is made of stainless steel (not lead), and the manufacturing facility has conducted their own tests which achieved a successful result, falling well below the California safety requirements.

    There are numerous points of potential damage in every home - sinks, toilets, bathtubs, showers, dishwasher, washing machine, water heater and toilets. With older pipes, weakened connections, valve failures, earthquakes, and many other causes, a minor leak can quickly turn into a big problem. Leaks don't just damage the things you can see, they can result in mold buildup behind walls and can even do damage to structural elements of your home, causing it to deteriorate faster, collapse, and possibly cause injuries to its occupants.

    Use the Smarthome SELECT Electronic Water Shutoff Valve as part of your whole home automation and security system to maintain a safe, leak-free environment.

    If you have a 1-inch main water supply pipe feeding your home, Smarthome also offers a 1-inch, 12V DC Electronic Water Shutoff Valve.

    * Note: This device does require a separate power source and a connection to a low voltage relay interface, as described above, for operation - these items are all sold separately. The Insteon I/O Linc transmits and receives signals via existing powerlines, so if you don't have any Dual-Band Insteon devices in place, at least one will be required on same electrical circuit as the I/O Linc for Insteon communication to take place.

    Part needed for BSPT to NPT conversion Review by Bruce
    Part needed for BSPT to NPT conversion

    Can someone provide the part number or link to the BSPT to NPT conversion? I tried a BSPT connector on it but it was unable to go much further in, only about 1/2 or a 1/3 of the way.

    Get the BSP to NPT adaptors for this very nice valve Review by Les
    Get the BSP to NPT adaptors for this very nice valve

    Steven is absolutely correct. I have two of these valves, and without the BSP adaptors, you will have grief trying to get joints to seal. And, if you do manage to get it to seal, you will likely have to revisit it in the future, discovering that you damaged the threads trying to make it work. If you are using this for your home water, you owe it to your family to buy the right fittings for this. That said, this is a very nice valve.

    Pipe thread problem -older model Review by Eric
    Pipe thread problem -older model

    I purchased one of these valves in August 2016 and got around to installing it on my household water supply line in early 2017. I decided to use 3/4" Shark Bite adapters on each end. I immediately discovered the 3/4" NPT threading issue with the SS valve body - Teflon tape was just shredded because of faulty female threading. My work around was to lubricate the valve and adapter threads with Vaseline and carefully turn the adapter in until 2-3 full thread turns remained exposed(a fine brass wire was peeled off the adapter thread). I then removed the adapters and wiped off the Vaseline before applying a small amount of TFE paste thread compound to the mating surfaces (you don't want to drive this compound into the ball valve!) Re-seating the Shark Bite adapters in the valve was easy and has proved physically tight and watertight and when installed.

    If you have purchased one of these valves with 'faulty' threads, I'd suggest trying to 'chase' the female valve threads with a high quality 3/4" NPT tap instead of the above. This should allow you to use Teflon tape without leakage or damage to the mated male threads.

    Other reviews have stated that recently purchased shutoff valves don't have the treading problem I encountered. I think the new shutoff valve design is functionally the same as the one I purchased in 2016. My shutoff valve works great with my Elk M1 alarm system - it automatically shuts off my home water supply when the alarm is Armed for vacation. The valve has drive motor limit control built in so there is no need to disconnect the power when the valve reaches the open or closed position desired.

    Pipe thread problem Review by Steven
    Pipe thread problem

    A number of posters have mentioned difficulty getting the pipe thread connections to seal properly. I've had the same issue with these valves from China - very good workmanship, but often the manufacturers use BSP instead of NPT fittings. You can't tell from looking, but they are slightly different and will not seal. You can buy adapters (which I did), and they work perfectly.

    Can power be left on after operating? Review by Gary
    Can power be left on after operating?

    Does the power need to be shut off after moving valve or can it be left energized until the next operation?

    Response: It will remain in the closed state until you trigger it back to open. You do not need to cut power between.

    Smart Home water shut off valve 70275 Review by Nerdy
    Smart Home water shut off valve 70275

    Challenge plumb existing spar bath water circuit into solar heating system.I bought a shut off valve 70275 as part of my plan, I accidentally connected negative to the black wire this caused the valve to fail ,my fault ,so I ordered another one. Upon instillation of the second valve I shortened the wires and stripped back the insulation to expose the copper conductors. After doing this the valve failed to work. I removed the electrical cover as I suspected the unit has many IC's and electronic components.These are obviously more sensitive to static discharge than your average electronic circuits. There are no labels on the outside of the device warning you of this!

    Good Quality Review by Insp Gadget
    Good Quality

    Installation was very easy. Fortunately I had a 12 volt power supply. I didn't realize when I bought it that it didn't come with one. Connection to the Insteon I/O line was no problem. Works seemly with Insteon App however, the red indicator is on when the ball valve is open and closed which isn't helpful. I haven't had much time to fool with it so I don't know if is suppose operate this way or if I have done something wrong. Would be better if the indicator changed to a different color for each operation (on/off).

    High Quality Valve Review by KC
    High Quality Valve

    Installed this valve into a pre-existing 3/4" PVC line feeding water to my pool, due evaporation losses. Installed just downstream of my manual valve. I've got it set up with the Insteon I/O Link relay which causes the valve to open or close (latched relay). Took a bit of tinkering to figure out which wires opens/ which wire closes (plus same issues with I/O relay ....), but figured it out by tinkering. Mine is set up where closed relay opens valve and vice versa. Although my feed water pressure is just normal residential pressure, I'm still somewhat surprised that it leaks zero water when closed. I've got my I/O Linc relay, the 12-volt power supply adaptor and extra wiring in a really "rigged" housing right now....a small pool chemical bucket with the lid on; and small holes cut in the side to run wires through (and I sealed it). Guess the pro way would have been a real enclosure for outdoor use, pretty well so far. I can adjust the timed schedule easily from my smart phone...i.e. if it's raining, I won't be adding water, etc. Valve appears to worth the money, in my case.

    Item#70275 3/4 inch electronic shutoff valve Review by Dusten
    Item#70275 3/4 inch electronic shutoff valve

    Once I found the following link using a Google search, setup was easy.
    It appears NPT thread issue is fixed. Used TFE paste and tightened down with some threads remaining outside valve fitting.
    When adding to my hub using the Insteon app, it's worth noting you will need to choose Relay Mode "Latching", not Momentary. I did have to add the device using Insteon ID, it wouldn't auto-detect, but system easily connected and setup device after entering it's ID. I successfully setup text alerts using app.
    Shutting off the water works well as a quick fix to dripping faucets keeping me awake at night. No instructions is my only complaint, I/O link came with instructions for irrigation valve, but didn't show wiring details. Including or linking to instructions would have earned this device 5 stars.

    Works, but care needed to prevent leaks Review by Steve
    Works, but care needed to prevent leaks

    As is stated in many other reviews, there is something very wrong with the pipe threads on this valve such that if you try to connect a normal 3/4" NPT fitting you will almost certainly have leaks. Even Teflon tape didn't help, but I found something that did: Oatey Megaloc thread sealant. You should be able to find this at "big-box" home supply stores and other plumbing supply shops. It has Kevlar fibers and doesn't harden. I found it also lubricated the threads allowing the fitting to tighten further than even with Teflon tape. I applied Megaloc to the threads of the valve and the fitting and tightened - no leaks!

    Once that was settled, I hooked it up to the Insteon I/O Linc and power supply (both linked from the product description). Note that you will need to snip off the barrel connector on the end of the power supply wire - take note of the tag indicating which wire is positive and which is negative. I see some reviews here mentioning a wiring diagram, but I see none here (and the valve comes with NO instructions!) The black wire is negative common and goes to the negative wire on the power supply. When voltage is applied to the red wire, the valve closes, so you would want this on the "Normally Open" terminal of the I/O Linc; the green wire opens the valve, so "Normally Closed".

    I created an Insteon scene with the I/O link and three Insteon leak sensors. It was not clear to me whether I wanted the sensors to turn "on" the scene or to turn it off. I THINK that the I/O Linc should be set to "Off". Be sure to test this.

    The valve itself closes within a few seconds and has a manual override.
