One of the most common reasons for water not flowing in your kitchen sink is a clogged drain. Over time, debris such as food scraps, grease, and soap scum can build up in your drain, causing it to become clogged. This can result in slow or no water flow in your sink. In some cases, using a plunger or a drain snake can help clear the clog and restore water flow.1. Clogged Drain
