I have a problem with standing water that keeps puddling up and never drains under where my valves are located for my sprinklers. What do I do? Should I just put 3/4 drain rock on top? Please help?
Sounds to me, like you have one of two things happening. Either you have a leak, which needs to be fixed. Or the valve box is in a low area where the water drains to... Turn on the water and watch the valves.. you might be able to see where the water is coming from. It may be as simple as tightening down the valve screws, or you may need to turn off the water at the main and repair or replace it. If the water is draining there or the leak isn't all that terrible the only way drain rock would help is if you were to dig underneath the valve a little, and to replace what you dig out with rock... Just make sure you can still access everything when you are finished. Good Luck!
