Currently my washer is on one wall next to a standing drainpipe and blocks access to an exterior door. I would like to move the washer to the exterior wall, next to the dryer, but that would require running the drain hose from one side of the room to the other.
I would like to run the hose almost completely straight up so it clears the door (the door is 7ft tall), then to turn and slowly slope down over the door, turn again (the distance between the washer and the corner of the wall is roughly 4ft), and then continue to run on a slope down the other wall (this distance is roughly 5ft) into the standing drainpipe.
I've read in a few places the water can still pump correctly as long as the hose isn't higher than 8ft, however, every video I've seen the drain is also that high and the hose doesn't then go back down. Also, would it be best to use a hose for the full length or can I use PVC pipe?
Any tips or advice would be greatly appreciated!
