A 3-inch diameter Schedule 40 PVC water distribution pipe is installed with a maximum developed length of 180 feet from the meter to the most remote fixture. The available static pressure at the meter is 55 psi, and the highest fixture requires 15 psi. Using a pressure loss of approximately 4.5 psi per 100 ft for this size and material, what is the approximate pressure at the highest fixture, and does it meet code?

• Approximately 52 psi, which is sufficient.
• Approximately 35 psi, which is insufficient.
• Approximately 39 psi, which is insufficient.
• Approximately 47 psi, which is sufficient.
