Solenoid Valve for Water Main
Hello,
I recently installed an alarm system in my home and as part of the alarm system want to install a solenoid valve right after my water meter. This would allow me to have the alarm turn off the water when we leave the house (and forestall a diasater should a pipe break). I have looked up solenoid valves on Grainger and believe the one shown below will work for me: http://www.grainger.com/Grainger/items/3UK70 My only concern is that there is no technical data if this valve is rated for potable water. Does anyone have any experience with this? Thanks |

That's a Normally Closed valve, so loss of power will also cut off your water supply. That's probably a good thing as well. Please post a followup as to how it works out for you. -- "Tell me what I should do, Annie." "Stay. Here. Forever." - Life On Mars |

Can someone in the know elucidate on the subject? Probably worth finding out before you go to the work of buying and installing it, just to make sure that the valve will remain open when no one is using water in the house, or if it close, that it will open from closed when someone turns on a 3 gpm faucet. And, if you do find it works as exspected it'd be wise to test it on a regular basis just to make sure nothing has cruded up and keeps it from closing when needed after a few months of inactivity.

They're ASCO valves, so went to ASCO site w/ the part number and looked -- no flow rates at all given in the spec sheet. There's a reference to an "Engineering Section", but no links and after almost 30 minutes poking around trying to find it somehow, gave it up... So, no real answer. There is a required minimum operating pressure differential (to overcome the inertia/drag of the solenoid when open to close it), so I suppose it's possible there's the requirement to generate that. That is, of course, conjecture. Overall, methinks OP is over-engineering a solution to a non-problem, creating others in its place... I'm interested in his proposed control input(s)/logic. BTW, it appears a reasonable choice for ASCO of valve family using their selection engine. Their only NSF-rated potable solenoid valves are limited to 1/4-3/8" so that's not possible from them even if OP wanted to pay the (undoubtedly sizable) premium for it. -- |

But, case in point... About four years ago my next door neighbor, an ob-gyn doctor, decided to close his private practice and move one state north to "Live Free or Die" in New Hampshire. He put his house here in Winchester, Massachusetts on the market for about $1.5 mil but didn't get a buyer by the time they were ready to move out in the fall, so off to New Hampshire they went, leaving the place in the hands of the real estate broker. Comes a January morning and as I was getting into my car I looked across at the side of his house and saw a bunch of huge dirty gray icicles coming down one of his garage doors: http://home.comcast.net/~jwisnia18/temp/freezer.jpg I had the sad duty of calling him up at the hospital where he was working in New London, New Hampshire and giving him the bad news. The oil fired hydronic heating system had conked out and domestic supply pipes and heating system plumbing had burst in several places, running for gosh knows how long before I saw those icicles forming. The contractors hauled away two of those huge dumpsters full of hardwood flooring, wallboard and all kinds of other stuff and it took until fall before the place was fixed up and put back on the market. Now, I swear on my honor that I'm telling the truth....The place didn't sell that fall and remained empty into the winter when it froze up AGAIN! The contractors and the construction dumpsters returned for another summer of tearing out and replacing walls and floors and the place finally sold to a nice young couple that fall. My old neighbors are nice folks, but for a smart doctor he "did stupid pretty good" with respect to not protecting his house properly. The place, like most of the homes in our neighborhood, has a monitored burglar and fire alarm system, but he didn't bother to add a freeze alarm to it, even after the first freezeup, when I suggested to him that he should look into doing that.

I think last year "this old house" had a device that
monitored waterflow at the meter (or just after) and closed the supply off if the flow exceeded so many gals/hr. It was like $200 for the valve and controller. And I think some areas now require a similar smaller device for the washer dryer connections, but it only opens the valves when the washer is pulling electric. google would be a good place to look ;-) -larry / dallas |

Well, I probably shouldn't have reacted back, but I specifically used the "quarter-turn" as I figured that had a better chance of registering w/ OP as to what it would be like in practice, and "quarter-turn ball isolation" valve seemed awfully wordy. I suppose to satisfy I should have shown a picture and catalog item number as well... Ah well, it _is_ usenet, and I _did_ choose to participate... -- |

This would allow me to have the alarm turn off the water when we leave the house (and forestall a diasater should a pipe break). What would cause a pipe to break? Freezing? In that case, if you also have alarm monitoring, have you considered installing a thermometer that will cause your burglar alarm to notifiy your monitoring company when it gets cold inside? That way, you might catch it when it is approaching freezing, but before it freezes or breaks. What kind of heat do you have? With some kinds, there are ways for the burglar alarm to know if the heat has failed, so you can notify the monitoring company even before it gets cold in the house, the first time the heating fails, especially if it requires manual reset, which will not be possible if no one is home. |

Consider automobile brakes. Originally, you stepped on a pedal which pulled a wire that expanded the brake shoes. Then came hydraulic brakes. Our '52 Hudson had both mechanical brakes and hydraulic brakes. At least my older brother told me that. It might have had one on two wheels and both on the other two. I wish I had looked. Then power-assisted brakes. Then dual-brakes. As someone whose brakes have failed 6 or 7 times, I do like dual brakes. I think on 3 separate cars the flexible brake line to a front wheel failed. Fortunately I was going slow and though I hit something each time, no real damage. Once I was stopped by an old chain link fence leaning against a lot of bushes. Power to the brakes also failed twice because the plastic tube, 1/2 inch, right angle, right at the brake booster at the hose from the carb, popped off its cap. Once for my '65 and once fcr my '67 Pontiac. Both times were the first times I drove the car, not counting driving it home after acquiring it! Once after my brother drove 60 miles to the Philly airport to go to Viet Nam, lent me his car for a year, and I drove it home. The brake vacuum failed the first thing the next day. On the '67, the part failed the morning after I bought the car. Is that eerie or what? Dual brakes would not have helped in these cases. I don't think I hit anything these two times. Also on my mother's '58 Ford Fairline 500, the metal brake line broke, right in front of the left rear wheel. When it was taken to the shop, she was told it failed because it needed linings, but that's not at all true, is it? That time, when the brakes didn't work, and there was a car turning left in front of me, I reached for the hand brake, and opened the hood. Then to separate the cars, I put the car in reverse, forgetting that it couldn't stop. But that time, I actually grabbed the hand brake and stopped it within 10 feet. That was good because the car was crooked now, and instead of staying in the left lane, I was backing into the right lane, on the main street in town. Fortunately, in Indianapolis, even the main street is quiet. 7PM on a Sunday at 28th st on Meridian St. So there was no one there to hit me a second time. I think once I've had a failure since I've had dual brakes. The light went on, I conclused the master cylinder was bad. I replaced it and things were fine, and I didn't crash into anything. Much better than the other 6 or 7 times. Now anti-lock. The number of parts in the brake system has grown by two orders of magnitude, each part with its own potential of failure. |

put solenoid on ball valve, quick pretty easy solution.
hot water tanks are a common leak point, if thats the concern make sure the tanks area has drainage to a safe spot. there are also rotary motor valves, to open and shut balves. a buddy has one in his car its used to turn off and on natural gas which powers his vehicles. one must be careful to not make something so complex it fails more often. the one shot solenoid, preferably using 2 solenoids on a ball valve is probably the ideal solution. water companies use electric valves thats another probably pricey solution. |
