What are the two pipes on the side of my house?

The two most common drain pipes that most people have on the side of their house are: Air conditioner condensate lines (AC drain line). Water heater pressure relief valve lines (PRV drain line).

Clogged Drain Line

The constant flow of water from the condensate pan to the drain line may result in buildups of algae and other mineral deposits. Of course, an accumulation of these deposits will restrict the flow of water, causing the water to back up and overflow in the drip pan.

Why does my condensate pump overflow?

Excessive flow. The drain line can get rid of excessive condensate, but the water still flows at a certain rate. If the build-up of condensation exceeds the line’s ability to remove the water, you’re probably going to get some overflow. This often happens when low refrigerant levels create ice on the evaporator coils.

Why is my condensate pan full of water?

When an air conditioner’s drain pan is full of water, the most common culprit is a clogged drainpipe. Inside the refrigerant coils and pipes is a breeding ground for algae, mold, and the like. Overtime, algae and mold can clog the drainpipe and cause water to build up and leak into the drain pan.

What is condensate overflow?

The condensate overflow switch serves to prevent the pan from overflowing if the AC drain stops working properly. The switch is activated when the level of the water in the pan comes above a certain point, causing the switch mechanism to trip/float to rise.

How does a condensate overflow switch work?

An HVAC wet switch/float switch, also known as a condensate overflow switch, serves to prevent this pan from overflowing if the AC drain stops working properly. The switch is activated when the level of the water in the pan comes above a certain point, causing the switch mechanism to trip/float to rise.

How does a float drain work?

Internal float drains insert into the bowl of a coalescing filter or moisture separator. Within the device is a float that normally seats on a small orifice. When liquid enters the drain the float rises off its seat, exposing the orifice and allowing liquid to discharge through the stem.
