Review on Big 5501 Drain Tame Maintainer Gallon by Brian Wright

Product description and delivery was good. The product itself is not as good as it could be. We have a 5,000 gallon trap and we purify about 3,000 gallons of water per day. Based on the price I think Big D has a good product but for the money Flo-Kem has a better product with a higher enzyme density per gallon at a slightly lower price. I will continue to use the Big D material unless there is another alternative. We used about 200 gallons of Big D and you can see the difference especially in the smell and BOD compared to Flo-Kem. You only need about 1/3 the amount of Flo-Kem for comparable results.
