I am trying to get an artisian well installed at my home located in Northeast Florida mainly for irrigation/sprinkler. My sprinkler has been designed badly requiring nearly 18 gpm per zone. I am getting different answers on what I need to go with as far as the well is concerned. Some say they will drill a 2" well and put a multistage jet pump. Some others recommend a 3" artisian with a submersible. Some others say, never go with 3" submersible, so go with a 4" well. One guy that offer to drill the well suggested that I go with a 2" well to 300' and do a 4" top for about 50' and put in a 4" submersible pump. Is this a good Idea ? He suggested going either with a 2" or a 3" well with the 4" top (upto 50ft for the submersible pump to reside). Please help me out as I need to make a decision quickly. Thanks to all for responding...
