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.

One-time installation of the Drain Guard T-body assembly with a slow releasing formula guarantees up to six months of drain protection. After the initial six months, a new cartridge (Model CM-08118 package contains 2 cartridges) can be installed to the existing Drain Guard T-body. With its transparent design, it is easy to see when the Drain Guard is activated. There are no complicated electrical components to fail and repair.
