What is the purpose of installing a cleanout in a house or building drain?

The purpose of installing a cleanout in a house or building drain is primarily for access to clear blockages. Cleanouts are strategically placed fittings in the drainage system that allow plumbers to insert tools or equipment to remove clogs or obstructions that can accumulate over time. By providing direct access to the drain line, cleanouts facilitate the maintenance and management of the drainage system, ensuring that blockages can be addressed efficiently without the need for more invasive measures, such as cutting into pipes.

This function is crucial for maintaining the overall health of the plumbing system. Regular maintenance through cleanouts can help prevent severe issues, such as overflowing drains or damage to the plumbing infrastructure, which can result in costly repairs or damages to the property. While other options may pertain to aspects of plumbing systems, they do not directly relate to the specific role of a cleanout in easing maintenance and ensuring the smooth operation of drains.
