A tube is connected to a cold water pipe somewhere close by for supplying water to the humidifier.
That tube will be connected to an electric solenoid valve located on the side of the humidifier which turns on and off the water flow to the humidifier.
The solenoid is controlled by a humidistat, which is wired to the furnace and operates when the furnace is on.
The water is dispensed through a metering orifice on the top of the humidifier down through an evaporation pad. Warm air from the furnace supply plenum flows through the evaporator pad , evaporating the water and passing moisture through to the air return plenum to be distributed into the home.
The excess water that doesn’t evaporate during this process flows out the drain tube located on the bottom of the humidifier.
Typically there isn’t any condensate pump normally associated with a humidifier. The drain tube usually is just gravity feed to a floor drain. Unless there isn’t a floor drain readily available then perhaps the installer needed to install one to move the water to a sink or other drain elsewhere.
Since the water source for the humidifier is the house water supply minerals will accumulate on the evaporator pad ---- which I suspect is where the confusion is.
Typically with the atomizing process a high percentage of the minerals collect on the pad and are normally carried off with the excess water being drained.
Part of the regular maintenance procedure is to remove the evaporator pad and clean it with a vinegar solution to remove mineral build up. If the evaporator pad becomes clogged with minerals it needs to be replaced.
Also, when the season changes to using the A/C the water supply should be turned off to humidifier along with turning off the humidistat control and setting the air damper to “ Low “ or “ Summer “. In other words--- it shouldn’t be left running all year round.
This might explain why the system worked for awhile and is now causing grief.
As for the mildew in your ducting --- perhaps you have the humidity level set too high or you may not even need the humidifier at all. You might putting too much moisture into the home.
