Septi-Flow Shock | Septic Drainfield Repair Solution, Clears Leach Fields, Dissolves Hardened Deadpan Soil, Complete Treatment, One Gallon - 128 Fl Oz (Pack of 4) - Drain Field Treatment

I think I received a defective bottle. One of the 4 gallon bottles had clear odorless liquid, not the yellow smelly stuff.UPDATE: Changing from 2 to 4 stars after Septi-Flow customer service reached out and 1) refunded my purchase so I could re-purchase a new batch, and 2) explained that "This product is made here in house (Atlanta, GA – USA) and it is likely that in between batches, they cleaned the lines and didn’t get all of the water out of the lines before filling the next bottles."I will update again in a few months after I have seen if it is effective.

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

If you have an old septic system that backs up every few months, buy the 4-gallon package of this stuff. Make sure to let your system completely drain for a couple of days before using it. I usually skip a day of showering and avoid washing dishes or using the sink for anything over those two days. That way the system gets the full effect of the 4-gallon concentration. At that point, I pour all 4 bottles into the toilet and let it work for another two days. I might take one quick shower over those two days, but that's it. You should see a dramatic drop in your septic level. Depending on septic system issues, you will likely need to do this again in 1 year.

After pumping the septic tank twice in 3 months due to water over the tank, dug up the distribution box. Grey water going nowhere, only way to get ride of grey water is by 5 gallon bucket. 4 showers, 1 load laundry and dishwasher daily adds up to many buckets. Ran a 50ft snake down the lines with no problem, ran it with a hose so that I could put in enzymes and Oxy treatments, No changes. Put 1 gallon Septi-Flow down into the lines, No change, no flow. Put small holes between 1 and 2 feet deep into the ground around the lines and using a turkey baster put diluted Septi-Flow into the soil around the lines. Took a bit to see results but I haven't had to use the bucket again. Still more work to go but would rather send $50 a month in getting the system better than replace a system where Title 5 now says I can't have one.

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.

l put 2 gallons in septic tank and 2gallons in drain field inspection pipe.It did not help at all.

(This is an updated review after 4 1/2 years - still using the product every 6 months and septic fields are still working great! As stated initially below, septic field failures are hard to diagnose. But once you get it cleared out, use this product to keep it clear.)It would be really hard to state that this item does or does not work. Septic field problems can be caused by so many different things as I have found out. When my fields failed, common sense told me that some liquid in a bottle was not going to fix my problem. I had my lines jetted first and then used a service that performs the "ground fracking" method to open clogged soil. Before they left they told me to use a product like this every 6 months to continually keep the soil conditioned. That was 2 1/2 years ago. My fields are still working and I cant tell for sure if this product works or doesn't. It was based on their recommendation. Since I haven't had any problems, I would say that it works. Most important thing I learned through this whole process - Do not run your water softener into your septic system!!!

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.
