Ask This Old House Season 11 Episode 7 Kitchen Sink, Sidelights

In Ask This Old House season 11 episode 7, titled "Kitchen Sink, Sidelights," the homeowners seek help in upgrading their kitchen sink and lighting. Host Kevin O'Connor meets with professional plumber Richard Trethewey to discuss the project, who explains the different types of kitchen sinks and their installation process. The homeowners selected a new single-bowl sink that requires some modifications to the existing plumbing setup, including adjusting the drain and water supply lines.

Next, electrician Scott Caron arrives to help the homeowners with their sidelights, which have been giving them trouble. The sidelights are connected to a three-way switch at the top of the stairs and a single switch at the bottom, but the wiring is not configured correctly. Caron tests the wiring using a digital multimeter and determines the source of the problem.

Back in the kitchen, Trethewey shows O'Connor how to install the new sink, starting with removing the old one and cleaning the area. The new sink is bigger and deeper than the old one, making it necessary to modify the countertop to fit it in properly. Trethewey and O'Connor install the mounting hardware and secure the sink in place, before connecting the drain and water supply lines.

Meanwhile, Caron reconfigures the wiring for the sidelights, which involves carefully tracing the wires from the switches to the fixtures. He connects the wires correctly and tests the switches to confirm that they are working as intended.

Back in the kitchen, the homeowners are thrilled with their new sink and the increased functionality it provides. They appreciate the guidance from Trethewey and O'Connor, and they are grateful to Caron for resolving the lighting issue that had been bothering them. The hosts wrap up the project and leave the homeowners with a beautiful and functional kitchen and improved lighting.
