If a pump is to be shut down for an extended period, what should be done to prevent damage?

To prevent damage to a pump during an extended shutdown, it is important to drain the pump to avoid corrosion and other issues that can arise from stagnant water or fluids. When pumps are left filled with liquid for long periods, moisture can lead to rust and corrosion on internal parts, seals, and bearings, which can significantly shorten the lifespan of the equipment. Draining the pump ensures that there is no liquid left in the system that could facilitate corrosion or frozen conditions if the temperature drops.

Although covering the pump with a tarp may offer some protection from external elements, it does not address the internal conditions that would lead to deterioration. Running a maintenance cycle can be beneficial for keeping the pump in good working condition during active use, but is not suitable for a situation where the pump will not be operating for an extended time. Leaving the pump as is also poses a risk as it does not account for potential damages from stagnant water or corrosion. Therefore, draining the pump is the most effective method to safeguard against damage during prolonged shutdowns.
