Folks:

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.

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.

David,
Thanks for your question.
It sounds as if you have corrosion either at the valve at the water heater or at the solenoid, when the valve opens you should have a constant flow of water, with the loss in pressure after the valve opens this is a textbook case of a stopped up valve. If you can disconnect the small tube that is on the outlet side of the solenoid and set the thermostat so you have a call for humidity you can possibly confirm this.
Please let me know if this is your problem.

David,
I just looked at your video. You have a restriction in the water line or most likely at the inlet side of the valve.
Have you removed the supply line from the inlet of the solenoid valve?
There is a small orifice on the inlet side valve, most are not removable, check and see if you have a obstruction there.

Thanks,
