It got backordered further out. Until late August.
Sigh. But it won't kill me. I can get to August....So I waited.
It arrived Aug 20, and the plumbers managed to stuff it into my basement (after removing the stair railing).
It fit fine into the intended location, and got hooked up for water on August 21.
However--because it arrived a few days early, I didn't have the electricians lined up. So although it was plumbed (?), it was not powered.
