Has anybody here ever actually did or seen some job where 2 loops were actually installed inside a single borehole? I have 2 DiY'ers in the past week want me to drill for them and install 2 loops per bore to save on the drilling cost. The first job was a 4 ton that wanted 2 300' borehole with 4loops total installed. The second was 6 ton with 3 200' bores with 6 loops total. We decided not to bid on these jobs since we have no direct experience with that set up. And all drillers know, it's always your fault when something goes wrong with the wells and/or loppfield.
