A stuck anti-siphon spigot
Its finally spring in MN and we went to turn on the water for our hoses. We have 3 anti-siphon spigots on the house. The plastic knob on 2 of them is stuck. Not the anti-siphon portion on top, but the knob that turns the water on/off at the spigot site. Any thoughts on why this would be so? We can't get them to budge. Thanks.
