Humidifier Water Line Hook Up

Humidifier water tap water is provided by tapping into an existing cold water supply line close to the humidifier often with a device known as a saddle valve.

Remove the cover and water pad from the humidifier and place the casing into the cutout on the duct. I noticed the water line for the humidifier taps a hot water and not a cold line. This aprilaire unit requires 6 screws. I know in many states the use of a saddle valve is now against code.

All humidifiers require a connection to an existing cold water line. This results in a trickle of hot water running through the unit and out the drain on the bottom whenever it s on. I needed to replace the crumbling humidifier pad on the aprilaire unit bolted to our new ng furnace. Using 1 long sheet metal screws mount the casing to the duct by running screws through the provided holes in the casing.

This was a surprise to me. That little nub cap on the valve is a drain port for draining the water out of the line when servicing it. Depending on where that line is in relation to your furnace you may need to add a new line to the humidifier. That needs to stay removable.
