I've been using Zep Septic Defense System for over a decade. They get the job done as expected. I hope to be using them for another decade. I highly recommend these septic cleaners.

I use this product once a month to clean out my septic system. The last time I had my septic tank cleaned out, the cleaner asked me if I used anything to clean the septic tank as he said it looked very good.

We have been using this product for two years now. It is easy to use on its recommended monthly usage.If you have a septic system- you know cleaning solutions, food in the garbage disposal, company visiting and days of rain in a row can affect the system in adverse ways. This product maintains the system that microbes need to breakdown solids in the tank in between your 3-5,year pump outs.I have tried other brands- some where one is required to measure the stuff out. I don’t like that feeling like I am breathing in the dust. This is perfect- pre-measured, sooo easy to use-and clean. It works far better than other brands I have tried before.

I procrastinated getting a plumber for the bubbling sounds in my ceiling on my upper floor so Im SO HAPPY this worked after the 1st pouch because I've been hearing those bubbling noises for weeks. Too bad that this couldn't help my sewer line in the basement so I needed a plumber but this stopped all bubbling ceiling sounds before I hired a plumber for the basement.
