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. Drain field opened without digging it up

    Posted by S.G. Warren

    After having the drain field leaking for a few weeks, I added Septic Flow over a few days and within a week there was no longer any leaking from the drain field.
    I was amazed at how quickly this product worked and recommend this to be used prior to digging up your septic drain field.

  2. So far, this product is a miracle

    Posted by Sharon M Allen

    We were told 6 months ago that our septic system had collapsed and we needed to install a new system - with cost up to $10,000.00. We had never had septic problems before but last October we went through a historic flood and soon many people were having septic problems. To be honest, $10,000. was a stretch for me and would have meant creating a bill. My son suggested we try this product. It's been close to 3 months now and the septic system is working as it always has. I'm not saying that we don't need a new system as ours is 34 years old but for right now this product has bought us time to save toward a new system. We are still seeing the effects of the flood as our water table which was about 1 ft. below ground is now at the surface of the ground. We have had several hard rains that have left puddles of water standing for several days but no problem with our septic system. It might be that this product, which I thought was a little expensive, has saved me $10,000.00!

  3. Great product & company

    Posted by Unknown

    My drain field is 27 years old and works well for a year or so, then needing the septic tank pumped out. I've used treatments toileted into the tank alone - the septic tank really wasn't the problem since it always worked well at storing and then creating 'liquid p**p' or effluent. The problem is the field, after 27 years, struggling to accept the effluent and having soil bacteria digest and break it down, as I've come to understand it.

    I was thrilled to find the product Septic Flow which promises to open up the soil down there where the soil must accept, spread out, and breakdown the liquefied p**p and the like.

    So, I used a screwdriver to poke a hole in the soil just behind where the tank outlet would be, to about eight inches or so. I then covered the hole with a plastic funnel to pour the Septic Flow into. I also poked a two foot or so thin, long wire (a straightened wire hanger would do the same) down the funnel into the hole to loosen the soil nice and deep. Then, I poured a whole gallon of Septic Flow into the funnel slowly until all of it was deposited down there nice and deep.

    I then picked three other spots, that spaced out, generally cover the major portion of the drain field, and then repeated to each of them what I did to the first hole.

    I did it this way because I'm in my sixties, not well, and can't tolerate at all that horrid, impossible Florida sun and humidity.

    My hope is that by doing it this way I'm giving
    my drain or septic field a healthy and generous enough amount of accessible and available Septic Flow product for it to go about the business of returning itself to 'like new' condition, flowing the product where it knows it needs it best, for best effect - better than I could do by poking holes all over and just putting a cup or two of Septic Flow down each hole!

    Time will tell!!!

    What I do know is that I'm thrilled that such a product to directly apply to the septic field exists, giving hope, better than indirect treatments down the toilet and into the septic tank do, believe me, I've tried them!

    Also, afterwards, I know no harm was done, none
    occurred, and now I have at least the possibility of a self-restored septic field since this is the first time in 27 years the field itself got treatment.

    I chose not to put product down the toilet since I wanted to treat the soil directly since that's where the problem is, at least for my system right now, and didn't want to just try another indirect technique - my choice.

    So, I'm a happy purchaser, rate the product and company very high (great product and free shipping just can't be beat!), and rate it five stars out of five!

  5. All around great experience

    Posted by Joe

    Had ordered 6 gallons of "septic flow shock" and was very excited when the shipment came in. But to my dismay 4 gallons was not what I had ordered. I had called the company, which they apologized for the mishap. UPS came by the next day to pick up the shipment and the rest of the *septic flow shock" came within 2 days. Had my drainfield pumped and applied to the "shock" to the distribution box and haven't had troubles yet. It's only been a couple weeks but so far so good. Very pleased with service and product

  7. Unbelievable !!!!!!

    Posted by Donna B., Crystal River, FL

    This stuff is absolutely amazing! I really didn't have much faith in this product, but thought I would give it a try before spending thousands on a new drainfield. It worked!!! No more drains backing up and it only took a few weeks. Thank you so much for an outstanding product.

  8. Saved me tons of $$!

    Posted by Jean T.

    We have had septic problems for over 7 years no on and off. We have tried powders form Home Depot and three different septic contractors. All three contractors said we needed a new drain field and possibly a new tank. We searched the internet and found your company. We applied the Septic Flow Shock product onto the drainfield soil and into the septic tank itself. The product did not work right away. We called and you said to treat again and give it another two to three weeks. Well it took four but the drainfield is entirely restored thanks to your great product! Save me tons of $$$ and aggravation from overflow of my laundry etc. Thanks so much!

  9. What a great product!!

    Posted by Nat K. Savannah, GA

    What a great product!! The area in my yard that was soft and had water pooling especially after a lawn mower would go over it, as it was never draining properly. We applied your product to the soil and in the "dbox" as you instructed. All I can say is that your product helped me and my husband take care of our pooling problem on our own for less than $300. This septic flow product really works! Our entire family thanks you so much!

  10. It worked wonders in just a few weeks!

    Posted by Jason Rovino, Buffalo, NY

    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!
