Can a toilet and sink share the same drain?

Sure! It is absolutely possible for a toilet and sink to share the same drain. This is a common practice in bathrooms where multiple fixtures need to be connected to the same drainage system. This type of setup is called a “wet vent” system. In a wet vent system, the drain pipe from the toilet serves as the primary vent for both the toilet and the sink. This means that the drain pipe not only carries waste from the toilet, but also allows air to flow through it, preventing any potential blockages and ensuring proper drainage for both the toilet and sink.

How far can a vent be from a toilet?

The distance between the trap and vent of a toilet in the UPC (Uniform Plumbing Code) is restricted to a maximum of 6 feet. This limitation ensures proper ventilation and efficient functioning of the toilet system.
