1 If your home plumbing system and the heater use the well system, the pressure from the ground can cause the air bubbles being entrapped inside the water pipeline. 2  Water under pressure contains more dissolved air than at the atmospheric pressure.
Water leaks in central air conditioners are almost always caused by a problem with the condensate pan or drain pipes. The most common of those problems is a clogged drain line. When your condensate drain line gets clogged, water backs up and builds up in your pan. With nowhere to go, that water will begin to leak over your drain pan and onto your system and your floor. Another problem that can lead to a water leak is a crack somewhere in the pan or in the drain pipes.
