Was looking at a condo in a 4 story building yesterday. This shot is in the laundry room at the laundry box in the wall. The unit was vacant so there was no washer there, but if there was its drain hose would be going down the drain opening.
Question is what the heck is the plastic pipe coming down from UP at the top of the laundry box. I thought it might be from the AC coils (up in the ceiling over the tub) so I ran the AC for 1 hour, but no condensate ever came out of the line. The water heater is a room away mounted on a closet type shelf SO as unlikely as it seems, I started wondering if this extra pipe could be from another unit.
IF it is a working drain of some type, WHEN the washer hose is in the drain opening HOW would any drainage from this line get into the drain opening??
PS … Neither the exit point of the water heater drain line OR the condensate drain line could be located. Any thoughts???
