Patent attributes
A treatment apparatus for air conditioning and refrigeration system drains includes a body portion having an inlet, outlet, upwardly extending neck portion, and downwardly-depending reservoir extending below the inlet and outlet. The apparatus is installed with the inlet and outlet interposed in air conditioning drain line. A chemical insert cartridge is installed into the central cavity of the body. The cartridge includes a shell with a plurality of openings, and contains a quantity of biocide such as one or more biocide tablets, so that the tablets dissolve through the openings in the shell when exposed to the water in the drain line. As the drain water passes through the apparatus the biocide is released into the drain water, preventing algae growth and discouraging insects and pests from occupying the drain line.
