Learn to Treat Drain Fields

What is Septi-Flow?



Septi-Flow is NOT an enzyme or bacteria. Enzymes and bacteria have a great place in a septic system, but they do nothing to address sodium build-up in the drain-field soil. This build-up causes the ground to lock up and not accept drain-field water over time.


Septi-Flow is not new science. It is a tried and true method to get your septic field flowing again. In simple terms, it is a chemical product used since the 1950s to help soften or loosen the soil surrounding a clogged drain field system to get it flowing again. It helps reverse "deadpan" or "hard soil" that has formed after years of sodium building up in the soil from the use of washing machine and laundry detergents, body and hand soaps with thousands of gallons a year pouring into your septic field that slowly accumulates sodium build-up over time, causing the soil to harden and not accept any more water or bio-nutrients from your septic system into the ground. Once the earth locks up, there is little left to do but dig up the drain-field system and install a costly new one.


Now you have a simple and inexpensive solution to digging up your entire septic system caused by locked-up soil.


How Do I Use Septi-Flow for Clogged Drain Fields?

To Shock Slow or Sluggish Septic Systems:

Start with 3 gallons of product. Use 1-2 gallons of the product via the toilet, sink or drain closest to the septic system outlet. Next, After one week, add another 1-2 gallons. Flush freely with water to distribute it throughout the septic system drain field.

For Drain and Leach Field Maintenance:

Use 1 gallon every six months via the toilet or the nearest drain closest to the septic tank.

Restoring a Clogged Drain Field or Leach System:

Start with 5 gallons of product. Apply a minimum of 3-4 gallons of product directly to the drain field soil. Apply the last 1-2 gallons via the distribution box/cleanout or septic tank opening. Try draining as much excess water as possible before treatment for waterlogged systems. Use a hose and add 40-80 gallons of water to the distribution box with the product to ensure it makes it through the entire drain field system. If you can not access the distribution or "D-Box," it may be necessary to add additional product via the toilet or sink.
The directions may need to be repeated for seriously slow or completely “locked” soil, especially clay type soils.
Septic tanks can be hazardous as noxious gases can form in the septic tank. Opening the tank may release these gases, and precautions should be taken to ensure you do not breathe these gases.  If in doubt, have a professional service your tank with our products.

  1. Many thanks Septic Flow you saved me $6,700!!

    Posted by Bobby Tompkins, AL

    I had some problems with my septic for a few years. Finally my drain field was starting to show mud in my front yard from the lack of proper septic drainage. I had several contractors come a look at it. They suggested a full replacement of the drain field pipes for $3,900. I decided to find something on the Internet and tried this product. It worked wonders in just a few weeks! Much appreciated!

  2. Can't belive how well it worked

    Posted by D. Stevenson, OH

    Rarely do I write a review but after having my septic tank pumped 3 times at the cost of $750 only to be told that my soil was "frozen up" and the entire septic field need to be replaced for $5,400 did I try your product. All I can say is that it was the best $299 I have ever spent. My drainfield is back to normal after just 2 treatments. Many thanks!!
