I've used this three times and it has unclogged the drain field. no more wet or smelly drain field.

This is the 4th time I've ordered Septic-Flow but the 1st time one of the containers leaked. The product box was upside-down in the outer shipping box and it soaked thru the cardboard. It's a good product for old septic systems but I'm disappointed with the condition of this shipment (esp. since they raised the price almost 10% since last year!)

UPDATE -- CHANGE TO 5 STARS -- EXCELLENT CUST SVC !! The vendor reached out to me after seeing my review and agreed to send me a replacement shipment of 4 more gallons. I couldn't be more pleased with the customer service from BuyNaurally! Septi-Flow is a great product that has rejuvenated a 60 yr old drainfield at our summer cottage - much cheaper than installing a new septic system (over $20K here in NH). Again, I am extremely satisfied with their product and quick responses from Preston and Bill. Thx again.

We were to the point where our septic drain field (we have a drain well, in the southwest USA), was failing. They had done a repair and even done an acid clean and it was still filling to the top with normal, even conservative use. It was flooding the backyard and backing up into the house. This was our last ditch effort. I thought it might work because the previous owners had been draining the softener into the septic and figured it had caused sodium buildup. We used two gallons of this when the drain field was almost full (it is a 30 ft. deep pipe that drains through holes in the sides). After a week it was still full but maybe just a little lower. We used another two gallons. Next time we looked it was almost to the bottom. We used another two gallons about two weeks later for good measure. Have not had a single issue since. The next step was drilling a new drain field pipe at $10,000+. This was our last hope. It worked. Couldn't believe it. We plan to use two gallons every six months for maintenance. I would say, if you have septic issues that are stemming from the drain field not draining the water, this would be a good thing to try.

This was mainly for my dry well that my soft water regen line goes to. Over the years it has slowly become worse with overflowing, due to the salts that creates the hard-pan/dead-pan. It's been ~6 days after treatment and my unit regened on that 6th day. Dry well still overflowed as before prior to this treatment, so no improvement yet. I'll see if any better next regen cycle, being this product takes more than a week to effectively work? I only used a gallon of treatment in my small dry well in relation to a 1500 gallon septic system this product was designed for.

The other three gallons I used in my septic system as a preventable measure/maintenance semi-shock treatment. Two gallons directly into my effluent line going to D-box and field lines. Remaining gallon was poured into my tank, since I already had the lid off. Last thing I want is a failed drain field in the future.

Strong sulfur odor when using, which is no surprise being what the ingredient is and is somewhat expensive for what it is in my opinion.

Results TBD, hence only 3 stars. I'll update and change my rating if my dry well stops over flowing.

-edit- 8/8/2019. Dry well hasn't overflowed last few regen cycles. Takes awhile to work on dead-pan, but it works. Upgraded to 5 stars.

4 stars because I don;t know it it will do as advertised yet. Love it';s Made in USA.
