We have a 7 zone sprinkler system that has not been getting enough water pressrue to keep the sprinkler heads up during lawn sprinkler application. After having the pump and valves checked by a professional we were told that we probably needed another well point. AFterward, we decided to try and install one ourselves but first thought we should figure out what we already had. We discovered nine well points along a straight line. From what we've read, we should need no more than six. We thought that maybe since they were in a straight line, the closest wells might be getting sucked dry. We reworked the well system to have six wells manifolded such that each one is an equal distance (pipe run) from the pump and so that none were less than five feet from each other. We found the static water level at 5'. We washed the well points down to about 17' making sure all the pipe joints were properly sealed. Water was running clear at this point and we could not get the casing down any further (2 inch casing with teeth cut into it was used for augering). We have a 60 Cycle Self-Priming Centrifugal pump. When we tested the "new" system, we still had low water pressure and the water is now dark brown. We tested the discharge form the pump - at the pump before it got to the valves - and found we only get 8 GPM... We have no idea what to do at this point. Neighbors have no problem with their water pressure. Help please!!!
