You were lucky.
If Costco puts their name on Italian or German faucets, then you may need to keep looking. WaterRidge isn't a real brand name. It's what the Costco buyer sells whatever he buys under.
Have you ever seen a "waterridge" web site?
Which by the way, when I moved into this house, it had a WaterRidge faucet. Frankly, it wasn't very good and everyone complained until I replaced it.
