When multiple dispensers are experiencing slow flow for a specific product, the most logical step is to check all product piping for leaks. This is because leaks in the piping can create resistance and reduce the efficiency of product delivery to the dispensers, causing a noticeable slowdown in the flow rate.

Additionally, understanding that product piping is a crucial part of the fuel delivery system is important. If there are leaks, not only is the expected product not reaching the dispensers properly, but there is also the risk of environmental contamination and potential hazards. Regular inspection of the entire product piping system is essential for maintaining the integrity and functionality of the UST (Underground Storage Tank) system.

In contrast, checking filters might be relevant if there was a perception of reduced flow across all dispensers for various products. Shear valves are typically employed to shut off flow in case of a break in the system but wouldn't usually cause a consistent issue across multiple dispensers. The PLLD (Pump Leak Detection) Shutdown is crucial in identifying leaks but wouldn't directly address the runtime issue across dispensers unless it had already triggered a shutdown.
