Have you noticed a pool of water in your AC system’s condensate pan? You don’t want to ignore this because overflowing condensate pans are often the result of pump failure.
The condensate drain pump is a water-pumping device that’s designed to extract water out of the condensate pan and flush it through the drain line. Not all AC systems require them. Some of them rely on gravity to prevent water from accumulating in the condensate pan.
If your AC system has a condensate drain pump you’ll need to ensure that it works as intended. Condensate drain pumps can fail for the following reasons.
#1) Disconnected Pump
If your condensate drain pump is disconnected it won’t be able to pump water out of the condensate pan. There are different types of condensate drain pumps, but nearly all of them require electricity from an adjacent power source.
#2) Faulty Float Switch
A faulty float switch may prevent your condensate drain pump from working. Most condensate drain pumps work in conjunction with a float switch. As the water level of the condensate pan rises, the float switch will activate the pump. As the water level drops, the float switch will deactivate the pump.
#3) Faulty Check Valve
A faulty check valve may prevent your condensate drain pump from working. The check valve is a small valve that allows water to leave the pump while simultaneously preventing water from reentering the pump. If your condensate drain pump has a faulty check valve, it may no longer flush water out of the condensate pan.
#4) The Pump Is Clogged
Water must flow through your condensate drain pump. If it’s clogged, it won’t be able to travel through your condensate drain pump, nor it will leave the condensate pan. Instead, the water will continue to build up in the condensate pan.
#5) The Drain Line Is Clogged
Perhaps the issue isn’t with your condensate drain pump but rather your drain line. Condensate pans have a built-in drain line at the bottom. The drain line runs to the exterior of your home – typically around the condenser unit. If the drain line is clogged, your condensate drain pump won’t work.
