Septic-Flow Shock is not a new product. In fact it's chemical make-up (calcium polysulfide) has been in use for over 60 years and was originally developed by Chevron ORTHO in 1953 and is still in use today. Septic Flow Shock helps chemically aid in reversing "deadpan" or "hard soil" that forms after years of sodium building up in the soil.
For Slow or Sluggish Drain Fields/Septic Tanks:
Start with 3 gallons of product. Use 1 gallon of product via the toilet, sink or drain closest to the septic tank outlet. Next, if the soil is visibly holding water apply 1 gallon of product into the drain field soil directly. After 1 week add another 1 gallon.. Flush freely with water to distribute it throughout the septic system drainfield.
Restoring a Very Slow or Failed Drain Field or Leach System:
Start with 5 gallons of product. Use a long wide screwdriver and poke holes about 6-10 inches down about 1 foot apart, into the soil above the drain field. Apply minimum of 3-4 gallons of product directly to the holes you have made. Apply the final 1-2 gallons via the septic tank opening, d-box, or the toilet closest to the septic tank. For waterlogged systems, try to drain off as much excess water as possible before treatment. Use a hose and add 40-80 gallons of water to the distribution box with the product to ensure it makes it through the drain fields entire system. If you can not access the distribution or "D-Box", it may be necessary to add additional product via the toilet or sink.
