How to Install a new Delta single handle bathroom faucet and pop-up

Once you've removed your old faucet, it's time to install the new one. Many single handle faucets allow you to install them as either a single-hole mount or as a three-hole mount using an escutcheon plate, which fits into the two outside holes. This video from Lowe's and Delta shows you how to install the faucet with the three-hole mount. You'll need a channel lock pliers, adjustable wrench, thread seal tape, silicone caulk and a wrench.
