How to Install a Single-Handled Faucet
Many of today’s faucet manufacturers have a line of easy-to-install single-control faucets designed for do-it-yourselfers. It’s easy to install because it’s accessible almost entirely above the countertop. No more lying on your back crammed into a dark cabinet. The manufacturers have figured out a way to preassemble the unit, which alone is revolutionary. Just knowing that you’re not going to face a bag of strange-looking unfamiliar parts and the challenge of installing them correctly makes the unit a godsend for DIYers.
The nastiest part of this job is emptying the stuff under the cabinet so that you can reach inside to hold the faucet while you tighten it. You need only two tools to install the faucet: an adjustable wrench and a screwdriver. Follow these steps:
Drop the flexible supply lines through the holes in the sink.
Align the center toggle with the center hole in the sink and push the valve body down to force the toggle through the hole.
Use a standard screwdriver to tighten the setscrew in the back of the faucet body.
You may have to hold the toggle that’s now underneath the sink to keep it from turning.
When the toggle reaches the underside of the sink, firmly tighten the screw to lock the faucet in place.
Thread the caps of the flexible supply lines onto the stop valves and tighten them with a wrench.
Whenever you thread fittings onto a pipe, you should apply Teflon plumber’s tape to male threads and pipe dope to female threads to help seal the joint and reduce the chance of leaks. Compression fittings used to connect riser tubes don’t require tape or pipe dope.
