I am having a WF Envision system 4 ton installed they were going to directional bore 4 3oo ft loops but due to rock they will now going to dig 2 2ft wide trenches 300ft long and install the 4 loops in those trenches. It sounds to me that's a lot of pipe in a small area. I just want to make sure this is a viable option. I am loacated in NE Missouri. Thanks for any incite on this.
