No water flow to the humififier
I checked to replace the water pad on my aprilaire model 110 humidifier today, lo and behold the water pad still looks brand new telling me that water wasn't flowing to add humidity. Water valve is open, there's power to the unit, i set the humity setting to 20 deg outside temp so water would flow, still nothing happened. I need your help to fix this problem. Thanks.

I've been working on the Aprilaire 110 unit today, after encountering the same problem. Here's how I fixed it: First, with the humidistat turned to 0%, I turned off the water supply saddle valve all the way (all the way to the right)--and then turned it back on all the way (all the way left). Still no water flow. Second, I slightly loosened the inline valve nut on the discharge side of the solenoid on the side of the 110 unit. Water began flowing, so I tightened it back up; and now the water flows freely. Conclusion: You may have some mineral deposit buildup in your lines, as I apparently did.
