Buying Guide

  • What is your condensate volume and lift height? Choose a pump with a higher GPH rating and vertical lift if you have tall drains or multiple devices draining into one line.
  • Do you need automatic operation? Dual water level sensors or float switches ensure hands-free drainage and reduce overflow risk.
  • How compact should the unit be? Wall-mounted or ultra-compact models fit tighter spaces and closets behind HVAC units.
  • What tubing and inlet options are available? Five inlet ports or adjustable barbed outlets improve compatibility with different hoses.
  • Are safety features important? Look for pumps with check valves to prevent backflow or overflow alarms for basements or utility rooms.
