Since there are quite a few science minded posters on here, I thought it might be worth a shot to ask about my septic leach field problem. I have a 900 gallon septic tank with 330' of field lines that snake out from the tank. It travels 90' south, then crosses over and travels 90' north, crosses over and travels 90' south, crosses over one last time and travel 60' north. There is lots of sludge on top of the third 90' section and sometimes a little bit at the end of the second 90' section. It appears the waste is not making it to the 60' section at the end, probably due to a blockage or a collapsed line (no trees anywhere close). To dig will cost lots of $$$, but it may come to that.
Before we dig, I would like to explore chemical possibilities. I have looked online and found products like Septic Seep which uses Calcium Polysulfide to open up the soil to increase permeability and has an additive to dissolve grease. This product is flushed into the system. Also, there are oxygen based products like Septic Scrub which are placed into the junction box and flow into the leach field. The active ingredient in these products is the same as oxy-clean, which would be the least expensive alternative, my septic system diagram I got from the county show a junction box. I'm thinking there may be one an each of those 90 degree turns. Does anyone here know anything about this subject? It would be great is these products would work, but I don't want to just throw my money away. I guess I'm hoping there is a BBB septic solution. Thanks!
