Water running from furnace

Ask a Plumber

I have a Honeywell humidifier on my furnace.  There is a tube running from the humidifier to the floor drain.  Water runs down that tube constantly into the floor drain.  Is that normal?

  1. Yes it is normal. What you describe is called a Flow Through Humidifier, and it is normal to have water coming out of the humidifier drain tube while it is operating. There are other options on the market now that reduce the amount of water coming out of the humidifier. A furnace technician could explain the different options that are available for your particular system.
