Described herein relates to an apparatus and method for optimized dispensing of conduit cleaning agent(s). The apparatus may be configured to dispense cleaning agent(s) (e.g., vinegar and / or acetic acid) into a conduit line (e.g., a condensate drain) at predetermined timed intervals. The apparatus may be adapted for multi-unit dwellings where conduit pathways are shared between different units and air conditioning systems. The apparatus may include a plurality of timer-controlled valves (e.g., motorized valves), which may be synchronized to simultaneously release the cleaning agent(s). Additionally, the apparatus may comprise a reservoir that may gravity feed the cleaning agent(s) into these integrated timer / release valves. As such, activation by the timer may cause the release of the cleaning agent(s) into the conduit line via tubing. Accordingly, the system may be configured to prevent substance accumulation / occlusion in the conduit line of a HVAC, refrigeration, and / or septic systems, and / or minimize the need for regular maintenance.
