What is required to be indicated on a sign at the dry pipe or pre-action valve regarding low point drains?

The sign at the dry pipe or pre-action valve must indicate the location of the low point drains to ensure that personnel can quickly and efficiently identify where to drain water that may accumulate in the system. This is essential for maintaining the integrity of the fire protection system by preventing freezing in these areas, ensuring proper system operation, and reducing the risk of water damage or fire hazards.

While information like size, freeze points, or risks are valuable, prioritizing the location of the low point drains is crucial for immediate action during maintenance or emergencies. This clear identification aids in the prompt draining of residual water, especially in environments subject to freezing conditions. Recognizing the need for quick access to this information helps ensure that firefighters or maintenance workers can maintain optimal system functionality.
