Product review (1 stars): will not work for 1" sidewall pipe.
this will not work if you need to drill a 1" hole in the sidewall of the pan. the description is totally misleading. maybe it means "bottom side" or "bottom back"? we got this one thinking it would work for our washer with the SIDEWALL drainage pipe and it absolutely did not. we drilled the hole in the side but because of the slope of the side it just simply wouldn't work. just going to recycle it and somehow find a different one with non-sloping sides. pain in the butt.
