When it comes to renovating or building a new bathroom, it's important to have a good understanding of the basic plumbing requirements for your sink. The plumbing diagram is a crucial tool that helps you understand how the water supply, drainage, and vent systems work together to ensure proper functioning of your bathroom sink.

Before we dive into the different types of diagrams, it's important to understand the basic components of bathroom sink plumbing. The main supply line brings in fresh water from the main water supply to your sink. From there, the water travels through the hot and cold water valves, which are controlled by the faucet handles. The sink drain connects to the main sewer line through a P-trap, which prevents sewer gases from entering your bathroom. The vent pipe allows air to enter the drain system, preventing suction and maintaining proper drainage.Basic Bathroom Sink Plumbing

In addition to the sink, there are other important components that need to be considered in your bathroom plumbing diagram. These include the toilet, bathtub, and shower. The toilet connects to the main sewer line through a toilet flange, which helps secure the toilet in place and provides a seal to prevent leaks. The bathtub and shower drain connect to the main sewer line through a P-trap, just like the sink drain.Basic Bathroom Plumbing Diagram
It's also important to understand the difference between a wet vent and a dry vent in your bathroom plumbing setup. A wet vent is a vent pipe that also serves as a drain for a fixture, while a dry vent is a vent pipe that only carries air. It's important to ensure that the correct type of vent is used for each fixture in your bathroom to maintain proper drainage and ventilation.Bathroom Plumbing Diagram
