For DTRs, how many seconds should water lines be flushed between patients?

Flushing water lines between patients is a crucial practice in preventing the contamination of water supply systems in medical facilities. The guideline of flushing lines for 30 seconds is aimed at ensuring that any stagnant water, which may harbor bacteria or other contaminants, is expelled from the system. This practice is particularly important for dental treatment rooms (DTRs) where instruments may come into contact with water supply lines.

Flushing for 30 seconds is considered sufficient to ensure that fresh, uncontaminated water is being utilized, thereby minimizing the risk of infection or exposure to harmful microorganisms. This timeframe balances effectiveness with efficiency, ensuring that necessary precautions are taken without unduly prolonging the treatment interval for patients.

In contrast, lesser durations may not adequately rid the lines of potential contaminants, while longer durations could disrupt workflow unnecessarily. The 30-second guideline has been established based on health regulations and best practices to ensure patient safety and public health.
