Replacing a Kitchen Sink – How to Install Faucets and Drains
With Bruce Norman
After realizing that the old sink is rotted beyond repair, plumber Bruce Norman demonstrates how to install a new sink.
Fit the sink to the countertop
All new sinks should come with a template for cutting the hole in the countertop that the sink will drop into. The template will also show how wide the lip of the sink is, to help you plan the clearance you will need around the hole. Use the template to lay out the hole, and then cut it with a circular saw or a jig saw.
Install the fixtures before you install the sink
It can be difficult to fit and tighten down the drain, faucet, and any other fixtures, if the sink is already attached to the cabinet. To minimize time spent crawling under the sink, attach everything you can before you drop the sink into place. Use beads of plumbers’ putty to seal where fixtures meet the surface of the sink. After the faucet and drain are in place, attach the water lines that will connect to the water-shut-off valves inside the cabinet. Sink water lines usually have rubber o-rings so you shouldn’t need to add any teflon tape or sealant to the fittings – just thread them on, and tighten them down.
