Seven “down-and-back” loops, 600’ long, 10-11’ deep. No one is getting into any of these for obvious safety reasons. Does assembling and fusing the 3/4” into my 7-loop manifold above ground and then putting it into the trenches sound like a plausible idea? The supply and return will be roughly 140’ each way of 2”. The other option is digging a much wider spot for the manifold and make it stepped so it is safe to get into but that is MORE digging! Appreciate input!
