I have a planter at an old theater on one of our high school sites that's been giving me fits over the past couple of months. It was originally on a SoloRain controller which hung up a couple of times so we ended up converting it (and all remaining planters) to Hunter WVCs. All was fine for awhile and then two weeks ago I get a call that the valve (Hunter ASV) had hung up and flooded the planter. Checked the valve and all was fine so put it back into service. Then, last week I get the same type of call. However, when I get there the curb stop isolation has been turned off so now I'm trying to find out from the guys exactly what was happening to no avail. Planter is so flooded that I can't go further, let it dry out for the week and then turn the isolation back on but turn the valve and controller off, suspecting that there might be a supply line leak. Yesterday I swing by to check things and sure enough... flooded again. But now I know what is happening so I turn the curb stop off again. However, I can't pump the water down because my Honda pump sucked up so much "walk-on bark" the last time that it was down for repairs. So... we'll let it dry out and then I'll have to look for a leak under the concrete pad. If I can't get to it then we'll have to tear the concrete out, make repairs and then put everything back. The leak apparently was not enough to see in the past due to all the water. But now that I know what the problem is that sucker is mine!
