Why Your Furnace May Be Leaking Water
A furnace leaking water may be due to a plugged drain line. The drain line can be removed and flushed or may need to be replaced. High efficiency furnaces produce water, over time the drain line can grow algae and plug the line causing water to back up into the furnace.
Humidifiers can also be the cause of leaking water. As humidifier pads age, pieces of the pad can break off and go into the drain line and plug it. The humidifier also needs annual maintenance at the same time as the furnace.
