I purchased and installed this two years ago after my septic was failing and was quoted 10-15 thousand dollars to replace. I wanted to give it time before making a comment. I opened the septic for the first time since installing it (which is simple) to have it pumped and can't believe how well it's worked. My septic hasn't given me any problems since putting it in and operates just like a new system. If you are having problems with your septic and thinking this wont work, guess again. I was skeptical but figured I would give it a try. Glad I did. You will not be disappointed.
