The DrainMaster system for automatic injection into restaurant grease waste systems from Cape Cod Biochemical Company is designed to take the guesswork out of applying a grease waste maintenance product into commercial applications. It is automatically injected using a timed metering pump that can be programmed to inject as much or as little DrainMaster as needed on a daily basis. Daily injections lessen the amount of product necessary, saving money on service intervals. 800/759-2257; www.septiconline.com.
