Furnace Humidifier

A few months ago, when the furnace was running more, i realized that it was getting really dry in the house. I checked the humidifier on the furnace and realized that it was bone dry.

This is the second time in two years that it's happened. I figured that the solenoid that i replaced last year must have been clogged. Water is forced at 150psi through a tiny hole. This time i ordered a new generic solenoid valve with a changeable orifice. That way if it becomes clogged i can just change the orifice and not the entire solenoid.

Here's the 3 solenoid valves. The left one is the original part, the middle is the replaced solenoid and the one on the right is the generic solenoid.

Here is a close-up of that solenoid, the yellow orifice and the cone filter to help keep the orifice clear.

I connected the water pipes and wires, turned up the humidistat to 60% humidity and it works just fine now.
