ECO-DRAIN Drain Maintainer from Bionetix International is a natural drain maintenance option to improve flow and prevent clogging of pipes without the use of harsh chemicals. The citrus-fragrance liquid contains microorganisms and biological nutrients and stimulants that, when applied on a regular basis, reduce the accumulation of grease, fats and a variety of other organic matter in pipes, sumps, drains, traps and garbage disposals. By degrading the grease and organic buildup, water is free to flow through the system. Regular use keeps pipes clean, prevents emergency blockages, saves on line jetting and reduces odors. Apply once a month by pouring down the sink or toilet at a dosage of 3.4 ounces per 2-inch pipe. It works best when applied at night so the microorganisms have time to establish a healthy biomass at a time of low pipe usage. 514-457-2914; www.bionetix-international.com.
