The Nu-Calgon NUCAL-61308 is an AC drain sucker kit designed to clear clogged condensate drain lines and remove standing water from drain pans. Condensate drain pan overflows rank among the most frequent service calls in residential and light commercial HVAC work. The kit uses suction to pull slime, sludge, and standing water out of the drain line quickly. It also includes a Purcool Green 3-ton tablet that dissolves into the pan to treat remaining biological growth and keep drain lines flowing freely for months after service.
This kit is used by HVAC technicians servicing split systems, package units, and air handlers where condensate drain pan overflows are present. It is suited for both corrective service calls and routine preventive maintenance visits. The sucker tool handles the immediate clog removal while the tablet provides ongoing biological control in the pan and drain line.
Designed for use on residential and light commercial air conditioning systems with standard condensate drain pans and PVC drain lines where slime and sludge buildup is causing overflow conditions.
HVAC technicians should shut down the air handler or furnace and set the thermostat to off before servicing the condensate drain pan or line. Confirm the suction tool seal is properly seated at the drain access point before applying suction to avoid splashing. After clearing the line, place the Purcool Green tablet directly in the drain pan per the tablet directions. Follow local mechanical codes for condensate drain maintenance and secondary drain pan requirements.
