Drain Guard was developed due to the alarming number of nuisance air-conditioning service calls for clogged drain lines. Drain Guard is Patent Pending, Laboratory Tested and Specifically Designed for Drain Guard.

For cartridge replacement, twist the expended Drain Guard cartridge off the T-body assembly and reinstall your replacement Drain Guard cartridge. Cartridge is a sealed system and there is no need to try and break bag open it is water soluble it will activate when water enters cartridge. DO NOT glue the cartridge to the body assembly as this is a self-locking mechanism with a gasket seal.
