Put into service in 2012 and have had phenomenal results ever since. I was told that I needed to completely redo my drain field at a huge expense. Within two weeks I found no liquid filter pipe or the field breather whatsoever. That's six years ago and it is still the same today. It rains over 45 inches a year any my property is at the bottom of a very large $@!#% so lots of natural ground water and yet it still works great. Thanks you so much for the $9,000 + savings.
