Originally the water for my humidifier was taken by flexible copper tube
connected to self piercing valve. The valve was installed below the heater
cold water shut off valve (the shut off valve shut water both for heater
and for humidifier). I recently had to move heater and re-solder some pipes.
I then reconnected humidifier tube and self-piercing valve above the heater
shut off valve. I fully opened the self-piercing valve for humidifier. Now
humidifier started to dip water, after night I found a lake under the
humidifier as if it gets too much water. Why this happens?
