First, the good news. Lots of pull-down faucets have an attractive profile and some sort of warranty. Most are made mainly of brass with a stain-resistant finish and have a valve with ceramic discs, which is just what the plumber ordered. Now for the hard part. There are dozens of brands, with prices all over the map. So This Old House looked at a luxury pick and its bargain counterpart to identify the qualities to ask about when you consider all the options in between. Surprises included an extra-long spray hose on the bargain model for easy maneuvering around a supersized roasting pan, and the DIY-ready fittings on the high-end model.
