Arrived to remedy a humidifier that seems to not be operating to its full potential. Checked the metering orifice to ensure there are no easily removable restrictions. Found that the humidifier is still not flowing enough water to fully utilize the humidifier panel. Spoke with homeowner about repairs. With homeowners approval started replacing the solenoid valve and humidifier panel. After removing the humidifier panel found that there is drain was heavily calcified. Cleaned the drain in the sink. Flushed the water feed line to the solenoid valve to ensure the new one won’t immediately get clogged again. Replaced the metering orifice to the humidifier and plumbed in the solenoid valve. Removed the humidifier panel and cleaned the bracket of what calcium buildup that will come off. Installed a new water panel and assembled the humidifier. Tested operation to ensure it will not leak. System is functioning properly at this time.
