All done with the install - made it all the way through without any water spills...until the very end. I had disconnected a hose for the original faucet, had the end in a container in case the water still in it began to drain (which it didn't), and then forgot about it ten minutes later when I unscrewed the spout on the other end of that hose. Well, the water drained then.
Would have been fine if the other end stayed in the container, but it didn't. Pretty minor spill, though.
The new faucet looks really nice. It's almost the twin of the one that I've been using for a year and a half, but with a bit more "flair."
One odd thing is that my Arbor model has a 2.2 GPM spout, while this one is 1.5 GPM. They are the same vintage of model, and really are essentially twins, as the instruction manual is actually for both of them (and it shows the Arbor in all of the pictures).
