Review: Best thing to treat your septic system - This is the best to maintain your septic system. it's very effective and easy to use. You just pour it into your toilet bowl and flush! We thought our leach line had collapsed (we heard gurgling), we were going to have to get our septic pumped out, but first we decided to treated it with Roebic K-37. If I remember correctly we ended up doing two packets within a days of each other. We had ignored our normal maintenance and things started happening. After treating our septic we waited with bated breath and it saved us a big bill. Now we treat our Septic regularly, every t here month's. That is one thing you don't want to have problems with is your Septic! Our lives are plagued with problems, but this is one you can do without. It's not expensive and worth the money! Highly recommend it!
