It’s not so much the weight A/B, it’s the awkwardness of moving, positioning and hooking up The plumbing/wiring, etc. My back just doesn’t work like it used to. The unit is in a linen closet ... close quarters which would require a lot of bending, etc. Much like replacing a garbage disposal under a kitchen sink (which I did a couple years ago and thought I’d have to call 911 to get me back out from under the sink). Heck, I have a riding mower sitting in the shed, yet have to pay to get my grass cut these days as my back can’t take the bouncing around. Trust me, I can’t STAND paying someone to do what I can do myself, but I’m just not physically able anymore. It sucks big weenies.
