Initial slow reaction but now very good
I recently had my septic tank emptied and soon after there was quite a bad smell as it started to fill again. I put one sachet and didn’t notice a difference so after two weeks added another and within days the smell had gone. I will now follow the monthly regime. Seem to be working well.

We have used OneFlush for the past 18+ years. Works exceptionally well! Much more potent than the leading branch flushable septic treatment. Quality: Compared to the leading branch, OneFlush is SO much more potent that it isn't even close. Check the specs and you will see. Results: We had our septic tank pumped 18 years ago. As an engineer, I knew that we had to use a septic system treatment needs bacteria to break down organic matter keep the system operating effectively and efficiently. I ran across a website of an engineer who "invented" a product that contained more than 9 Billion beneficial bacteria (the heavily-advertised leading brand makes the claim that it is a "Standard formulation, not marketed as super-concentrated". Hmmm, that about says it all. At any rate, the inventor sold his company to ProLab who continues to sell it today. Results: After 18+ years of use my septic tank is clean and functions well! Worthy of note: We are careful to not allow any bleach-based products, nor any "anti-bacterial" products, down the drain. Why? Septic systems NEED BACTERIA to function properly. Bleach kills bacteria. Anti-bacterial soaps, etc. kill bacteria! NEVER, NEVER, EVER allow any bleach or anti-bacterial products down your drain if you are on a septic system. If you do, be prepared to pay several hundred dollars every year or two to have the tank pumped. (Failure to do that will result in your septic system drain lines become clogged...expensive to repair!!!) Conclusion: After personal use of One Flush, once a month, I highly recommend this product. We have it on a Amazon subscription so it's delivered right when we need it. We also use it in our church's septic system and after 15 years, it too is 'clean as a whistle.'

Have been using this product for several years. Had our septic tank pumped recently and the technician said it was in great shape. He asked what we were using and if I could give him information on product. He was going to recommend to his other customers. That tells me the product works as advertised and is very economical compared to other products Highly recommend
