What device should be installed at each hose outlet in a standpipe system?

In a standpipe system, it is essential to regulate water pressure at each hose outlet to ensure that firefighters can operate the hoses effectively and safely. A pressure reducing valve is specifically designed to lower the incoming water pressure to a manageable level at each outlet, preventing potential damage to the hoses and ensuring that the water flow is usable for firefighting activities.

Furthermore, reducing excessive pressure is critical in preventing injury to personnel or equipment, as high pressures can lead to hose failures or difficult handling. The pressure reducing valve facilitates a consistent and safe pressure for all users, contributing to the overall efficiency and effectiveness of the standpipe system during emergency responses.

While flow switches, check valves, and backflow preventers are important components in a standpipe system for monitoring flow, preventing reverse flow, and ensuring potable water safety, they do not serve the primary purpose of regulating outlet pressure, making the pressure reducing valve the necessary device at each hose outlet.
