What is the maximum storage time allowed for a sump?

The correct answer is 12 hours because the Massachusetts Plumbing Code specifies a maximum storage time for a sump system to ensure that water does not become stagnant, which can lead to various issues such as odor problems and potential contamination. Limiting the storage time helps to maintain the quality of the water and ensures that the sump system functions efficiently in handling excess water. A storage time of 12 hours strikes a balance between practicality and safety, allowing enough time for the sump to collect water while preventing potential issues associated with longer storage durations. This regulation is important for both health and environmental reasons, as it helps to prevent the growth of bacteria and other harmful organisms in standing water.
