Sink Repair FAQs, answered by experts

Undermount sinks have clips that attach to the countertop, but they have pros and cons. They are heavier than drop-in sinks, so they only work with sturdy countertops like natural stone and are a more expensive option. You might need someone to help you install the sink, depending on its weight.

Local plumbing codes and manufacturer recommendations typically dictate the minimum distance between a sink and a dishwasher. This is generally 18 to 24 inches, providing enough room for easy loading and unloading of dishes without hindering the sink's function. Maintaining this separation not only adds convenience but also reduces the chances of water damage and optimizes plumbing connections.

A good option for opening up and cleaning a sink drain is to use a ¼ cup of baking soda and 1 cup of white vinegar, along with a rubber stopper to cover the drain while those materials work their magic. After about 15 minutes, you can flush the drain with hot water. In many cases, these materials can scrub out minor clogs and get the drain working properly again. If the issue persists, call in a plumber near you to get the problem permanently fixed.

The Thanksgiving holiday period is one of the busiest times of the year for plumbers. Both Thanksgiving Day and the day after, often called Black Friday or "Brown Friday" by plumbing professionals, see a significant increase in service requests. This is because a house full of guests, large holiday meals, and unfamiliarity with the home's plumbing can lead to clogged drains, garbage disposal issues, and sewer line backups. Outside of the holidays, the busiest weekdays for plumbers are typically Monday and Tuesday, as many people discover plumbing problems over the weekend but wait to call for service. Despite the holiday, you can rest assured that many plumbers work on Thanksgiving and Black Friday to handle the surge in emergency calls.

Depending on the issue, you have a good shot at fixing a leaking sink yourself. If you have some plumbing experience or are comfortable with DIY jobs, you can clean the P trap, tighten nuts, replace washers, and replace shut-off valve stems on your own. For more complicated jobs, such as repairing a garbage disposal, calling a pro may be the way to go.
