What is this pipe coming out of washer dryer box?

Question

See picture below. The tenant told me recently that there has been a slight constant drip coming from the PVC pipe in the middle. It is draining directly into the drain line, so there's no concern of water damage. I am just confused as to where this pipe leads to and its purpose. On the opposite side of the wall is the bathroom, but the sink and shower do not share this wall. The house is 1 story.

The slow steady drip makes me think it's the drain line for the air handler.

Is the heater and ductwork in the attic? It could be the condensate drain line from the AC coil.

Yeah I thought about that too. The drain line shouldn't fit flush so there should be some room left, but I definitely need to remind my tenant to position it carefully.

Thanks guys. This is exactly what it is. The furnace is located directly above this. Can't believe I didn't think of that.

this is a condensate line. that drip is supposed to happen. no worries as long as its dripping in the hole in the washer box.

Question is, what happens when you put the drain hose from the washing machine into the drain?

Yiv L. · Answer

I think it's soft water drain. My newer house in AZ has one like this. It's used to drain away during soft water cleaning cycles.
