What is the maximum distance allowed between sinks on a continuous fixture drain?

In plumbing systems, the maximum distance allowed between sinks on a continuous fixture drain is significant for ensuring proper drainage and preventing issues such as backflow or improper waste disposal. The correct answer is based on established plumbing codes that dictate how far apart sinks can be placed when connected to a continuous drain.

The maximum distance of 900mm (approximately 3 feet) is the standard measurement that allows for adequate flow and minimizes the risk of clogs and build-up in the drainage system. This distance helps maintain the integrity of the plumbing system while promoting efficient wastewater removal.

Choosing a distance greater than this can lead to potential problems, as longer distances might not allow gravity to assist effectively in drainage due to the reduced flow velocity in the pipe. Therefore, understanding this standard is crucial for plumbing design and installation, ensuring both compliance with regulations and functionality of the plumbing systems in a residential or commercial setup.
