Furnace Humidifier - Replace & Install

Our furnace humidifier filter got so coated with calcium buildup and the weight caused it to tear the whole unit off the side of the furnace. (my fault for not checking and changing the filter) So i had to replace the unit, but i was able to reuse the transformer, wiring, humidistat, and plumbing. So basically just replacing the housing unit that holds the filter and solenoid. 

I originally went to Home Depot and bought the only brand they had, Honeywell. But quickly realized it wouldn't fit in the opening and the water solenoid was on the opposite side - meaning i would have to reroute the pipe. So i returned it and bought the same model that broke. 

The original model was the GeneralAire 1099. The replacement model is the General Aire 1042 LH. (i think it stands for Legacy Housing?) The new version was perfect. Everything was in the same place and all the holes lined up. It was only about a 1 hour fix and has worked perfectly ever since.
