OverFlow / Drain Kitincluded when you purchase an autoflush
This kit can be connected to all Desert Spring humidifier models. It serves as an emergency overflow line that directs water safety to a floor drain in the event of an overflow caused by sudden excessive water pressure, float failure, etc. This accessory is recommended for all installations in attics or other finished spaces.
Please note: The overflow drain kit is now included free with the AutoFlush AF15 so this product is not necessary to purchase the overflow drain kit separately if you are purchasing an AutoFlush AF15 unit.
