Ok, I have read past posts, but they seemed to turn into professional slinky vs 6 pipe wars. I have 10 acres, what would you recommend for a large system I do myself. I am a newbie, but to me, it would seem almost easiest to take a trencher and just make long ass loops, or zig zag them in all over. There is no frost line here, so I just figure as deep as you can easily trench ? I can use a backhoe also if needed as I will have to have one on my septic. It is just a matter of more hours on the rental.
