What If the Problem Isn't Your Fire Pump, but What's Inside Your Water Tank?"

A fire water tank may have sufficient capacity, but that doesn't necessarily guarantee reliable fire pump performance.

One commonly overlooked component is the anti-vortex plate.

Without proper suction inlet design, vortex formation can introduce air into the piping, potentially causing cavitation, unstable flow, and reduced pump performance.

WHAT DOES THE NFPA FIRE PROTECTION HANDBOOK SAY?

As illustrated in the 21st Edition, Section 15, Chapter 1, a typical anti-vortex plate arrangement considers:

1. Plate Dimensions: Minimum 2D × 2D, where D is the suction pipe diameter.

2. Bottom Clearance: Minimum 1½D or 150 mm (6 in.), whichever is greater.

3. Pipe Arrangement: A long-radius elbow connecting the suction piping to the anti-vortex assembly.
