Product review (5 stars): When you need moisture in the house but not mold ...
When you need moisture in the house but not mold or mildew, you find a way to control the humidity. We use a whole house humidifier and when the solenoid controlling the water flow gets clogged, you simply replace it. Shut off the Main supply, bleed system pressure off, and replace the valve. Simple, 15 minute project. The exact part number needed is on the body of the valve.
