I would appreciate any guidance or direction anyone could provide me. I am lacking much of the technical information at this point that would be required to hone in on an actual 'root cause' however I am hoping that someone can help me get pointed in the right direction.

BACKGROUND:

I had a house built two years ago. At the time the city had not run water to my subdivision (new development). In order for people to move into their new homes the builder had wells dug. Once the city had run water to the homes the homeowner could decide to seal the well.etc. Most homeowners kept the wells to run their irrigation systems.

PROBLEM:
I had my sprinkler system put in after city water was available and hooked it directly to my well. I live on a small 1/4 acre lot and have 5 sprinkler zones. The first summer all of the zones seemed to have enough pressure to allow the sprinklers to run properly (40PSI I recall). The second year most of the zones are peforming adequately, however 2 of the zones are not working well at all. These zones are a bit larger than the others but not by much. I have had the sprinkler company out 3 times. They have said that the well is either running dry, not pumping water out fast enough...or that they don't know, however the sprinklers themselves are tuned and running perfectly. The neighbors to the left and to the right me me (and all that I have spoken to in my sub) all have good pressure on their sprinklers.

I had guy come out (independent sprinkler company) and winterize my system last year and he just fired it up for the summer. He tuned my holding tank to increase the pressure. For the most troublesome zone he has it set to 50PSI, however when the zone kicks in drops to 30 and I get very poor performance (ie heads won't lift up all the way......etc). He said flat out that I need a more powerful pump.

I know I need to pull my well log. The driller who put the well in 2 years ago for the builder won't come to see me for less than 500 bucks to perform a flow test. If I have to pay I have to pay but am looking for some insight here before pull out my check book.

Any help would be appreciated. Thx Much
