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.

HOW TO INSTALL (FOR AIR CONDITIONING CONTRACTORS ONLY)

Once a licensed air conditioning contractor has verified the condensate drain is cleaned and free of obstruction(s), the Drain Guard T-Body (Model MT-73018) may be installed. CAUTION: use only ABS to PVC transition cement, otherwise damage will occur. This is an ABS product. Once it is installed, the contractor will run the air conditioner system and look for any leaks as this is a totally sealed component; ensure all glue joints are watertight and that the Drain Guard cartridge has been clicked into the locked position. Insulate the T-Body when installing in an unconditioned space to prevent sweating.

For cartridge replacement, twist the expended Drain Guard cartridge off the T-body assembly and reinstall your replacement Drain Guard cartridge.
