I'm with ya Steve. No vegetation though, the line from my house to the plant is 2 or three years old. Our neighborhood was the last in the town to switch from septic to city.
Actually this is the 3rd time thi shas happened in 11 years. So there is an interval developing. Between my wife and daughter I'm sure this isn't the last.
BTW a big contributor to clogging is Washing machine lint. I wonder if I can make a filter with some off the shelf parts (seems to be a mesh bag inside a poly carbonate housing). This unit starts at $140! Any ideas?
