I've recently contracted for the installation of a WF 2.5 ton Envision system in my home and am awaiting issuance of the required permit from the state to drill. In my initial discussions with the contractor (experienced and reputable) he stated he was going to dig 2 wells, each 280'. Last week he came out with the driller and advised that it was going to be 1 well, 300' with 1 1/4" pipe. The contract does not specify the number of wells or their depth. I have just emailed him and asked him to explain the reason for the change, which seems pretty substantial to me. I'd appreciate any feedback from the members of this forum as to questions I might ask the contractor as to his reasoning behind the change as well as any other comments you might care to make. Thanks in advance. PLEASE NOTE: I received a reply from the contractor after I posted this message. He states that there was some confusion since several people were involved in the quote process and his initial statement to me that my system would have 2 wells, each 280' was made in error. The 2 wells were part of a different quote for another customer. My system was always calling for the one well. I will ask him for the design particulars the next time I see him. Sorry for any confusion (other than mine) I may have caused.
