During Rialto's 100°F+ summer heat waves, residential central air conditioners pull 5 to 20 gallons of water vapor out of the air daily. This condensed moisture drains through a 3/4-inch white PVC pipe to the exterior of the home.
Why Condensate Lines Clog with Algae
Warm, dark attic conditions create the perfect breeding ground for algae and microbial slime inside the condensate drain. When the line plugs, condensate overflows the internal evaporator coil pan into the attic, soaking through ceiling drywall and insulation.
Installing Inline Float Safety Switches
Every attic AC unit should feature a secondary drain pan and a digital inline condensate float switch. If water rises in the pan, the switch immediately shuts off the air conditioner compressor, preventing thousands of dollars in water damage.
