Question
Heres my question.  I noticed this morning (for the 2nd time in a row) that my sprinkler system will work fine for about 30min and then start spitting air and stop working.  I immediately turned it off for fear of damage.  I also want to note that our area is experiencing VERY low rain levels.  Could my sprinkler well (separate well from home well) be dry?  Other thoughts?

Answer
I want to be up front and let you know that I am not an expert in wells.  It is possible that your well is dry if it is putting out air.  Definitely do not run the well when this is happening - you will probably burn out the motor as most pumps rely on the water to cool them.  It could be that a suction fitting is loose somewhere allowing air to enter the system as well.  Your best bet would probably be to call a well company and run it by them.  They may know if people in your area have been experiencing wells running dry lately.  Sorry I can't be more helpful.
