A 2-inch vent serving a sump pump with a discharge capacity of 50 gpm may have a maximum developed length of how many feet?

The maximum developed length for a vent serving a sump pump is determined by various codes that are based on the size of the vent and the discharge capacity of the pump. In this case, a 2-inch vent connected to a sump pump with a discharge capacity of 50 gallons per minute (gpm) is allowed to have a maximum developed length of 135 feet.

This allowance is based on maintaining proper air flow and preventing the creation of negative pressure that could impede the operation of the sump pump. Adequate venting is crucial to ensure that the system effectively allows air to enter the plumbing so that proper drainage can occur without backup or siphoning. The 135-foot length is established as a standard to support these requirements for the specified parameters.

Other options are not correct given that they exceed the maximum allowable length for the specific vent size and pump capacity, which could lead to issues in system performance and code compliance. Understanding these parameters is essential for ensuring that plumbing systems operate correctly and in accordance with building codes.
