If all dispensers are running slow on one product, what should be checked first?

Filters
Check all product piping for leaks
PLLD Shutdown
Shear Valves

The correct answer is: Check all product piping for leaks

In a scenario where all dispensers are running slow on one particular product, the first thing to check is the product piping for leaks. This is crucial because leaks in the product piping can significantly affect the flow of fuel to the dispensers. If there is a leak, the system may not be able to maintain adequate pressure, causing a slowdown in dispenser performance. Inspecting the piping for leaks allows you to rule out one of the most common issues that can affect multiple dispensers simultaneously. If there is a problem with the piping, it can create a situation where the product cannot move efficiently, thus leading to the slow dispensing rate being experienced at all points of sale for that product. While other factors, such as filters or shutdown mechanisms, may also cause dispensing issues, the systemic impact of leaks in the product piping makes it the most immediate concern when addressing slow performance across all dispensers.
