Beware! If you use this on automatic know it sometimes does not shut the water off. This has happened to me twice with two different units. I returned the first and got a replacement; I'd had the second too long. In each case the unit worked perfectly several times then just didn't shut the water off. Water was on four hours one time, six the next. Both units appear to work now - but I don't use them (water hydrant is shut off) unless I can verify they have turned on and off as they should. If you use them on automatic I recommend you do the same!
