This question already has an answer here:
We have very limited space in our home for a washer & dryer. We are thinking about putting them outside. We have an outdoor patio where 3 sides are part of the structure (the house). There is also a roof which is part of the house. The fourth side is open. The cement is a step up, elevated from the rest of the patio. We live in Southern California, in the high desert near Mojave. The winters get as low as 20 degrees and the summers up to 115 degrees. We have a lot of wind and some rainfall but not a lot. When it rains, it rains hard. Also the yard is mostly dirt so the dirt blows around a lot. Would this work? Would we still need the air vent? Should we wrap the gas line, wires, etc. What about putting them on a platform, off the ground?
