Water flow for furnace humidifier

At my place recently, it was time for the annual changing of the vapor pad in my humidifier, so I did that.

While doing so, I wanted to check the water line coming to the humidifier. I turned up the furnace and set the humidistat to its highest setting. After letting it run for about 10 mins w/o seeing any water, I did then see it passed through the solenoid valve but the supply to the actual pad itself is only a slow drip.

Is that correct? I was assuming the flow would be a little heavier or constant, at least. I have verified the main water line is flowing and fully open as I gave myself a nice little spray accidentally when checking that.

I only worked on one of those. IIRC, the flow wasn't much more than the drip that you saw.

It's a very low flow so if working and you're getting the humidity level you need your good.

Welcome to the forums.

It would be very helpful to know the make and model of the humidifier.

If you aren't getting any water from the humidifier drain then your flow might be too low. You want the pad saturated enough that it gives up all the water the airstream can take from it.

Thanks, all.

Sorry - I should have mentioned the model - it's a GeneralAire 1042LH.
