6 hours
8 hours
10 hours
12 hours

The correct answer is: 12 hours

The maximum storage time allowed for drainage in a sump or ejector is 12 hours. This limit is established to prevent issues arising from prolonged retention of wastewater or sewage, which can lead to problems such as odor, bacteria growth, and other health hazards. Additionally, ensuring that the drainage system functions efficiently within this time frame helps maintain the integrity of the plumbing system and supports effective drainage performance. In plumbing systems, it is critical to have a designated time for storage to help manage water levels effectively and to ensure that systems like sump pumps can operate seamlessly without the risk of overflow or backup. By adhering to this 12-hour timeframe, operators can better ensure that their drainage systems are operating optimally and safely without compromising their functionality.
