What is a common practice with low flow toilets regarding flushing?

Flushing twice for solids is a common practice with low-flow toilets because these toilets typically use less water per flush compared to traditional toilets. Many low-flow models use as little as 1.28 gallons per flush, which is designed to conserve water. However, certain solid waste may require an additional flush to ensure proper clearing and to maintain plumbing functionality.

This practice emphasizes the balance of water conservation with effective waste removal. While it's beneficial to flush just once for liquid waste, solids often necessitate more water for adequate removal, thus the practice of sometimes flushing twice for solid waste becomes necessary in many instances. Understanding this practice is vital in promoting both environmental sustainability and effective sanitation in residential and commercial facilities.
