I've got a basic bypass humidifier attached to my furnace. It's controlled by a Nest thermostat.
I'm wondering how much water should be flowing over the evaporator pad.
I checked the water flow from the hot water heater to the solenoid and there's plenty of water there.
When the humidifier activates, the solenoid releases an initial burst of water (I'm assuming to fill the tube that goes to the distribution tray in the humidifier), but then it tapers off to a very slow drip.
Is this normal, or should I be seeing more water flow?
Here's a video of the water flow from the solenoid.
Example of the water flow
Before I installed the Nest, the humidifier was controlled by a humidistat and I seem to remember that more water was let through ... enough so that I could hear it going to the bottom of the evaporator pad and down the pipe to the floor drain.
Any help is appreciated.

That's a normal flow rate. If you think about it, even a slow drip like that will put several gallons per day into the system. Much more than that and it will just have to drain off as overflow - a waste of water.
