What is the maximum developed length for a pressure range of 40 to 49 psi with a 3/4 meter and distribution pipe?

In plumbing, the concept of maximum developed length refers to the longest run of pipe that can be effectively used without compromising water pressure at fixtures. When considering a pressure range of 40 to 49 psi, the standards and guidelines provide specific limitations based on the diameter of the pipe being used.

For a 3/4-inch meter and the associated distribution pipe, the correct maximum developed length is 100 feet. This figure is derived from established plumbing codes, which take into account both the pressure available and the distance the water must travel through the distribution system before reaching the fixtures. At a pressure range of 40 to 49 psi, the design ensures that even at the maximum developed length, enough pressure will be maintained to effectively deliver water to fixtures without experiencing excessive drop-off.

This understanding is crucial for ensuring that the plumbing system remains functional and efficient, which is why the specification aligns with code requirements to support proper water delivery. Properly assessing maximum developed lengths helps in planning and installing plumbing systems to avoid issues related to low water pressure.
