What water pressure level triggers the requirement for a pressure-reducing valve and a strainer with a bypass relief valve according to the Illinois Plumbing Code?

50 p.s.i.
60 p.s.i.
70 p.s.i.
80 p.s.i.

The correct answer is: 80 p.s.i.

The requirement for a pressure-reducing valve and a strainer with a bypass relief valve is activated when the water pressure reaches 80 p.s.i. This is important because excessive water pressure can lead to various plumbing issues, including leaks, pipe damage, and inefficient water usage. Implementing a pressure-reducing valve helps to maintain the water pressure at a safe and manageable level, protecting the plumbing system and fixtures. While other pressure levels are mentioned, they do not meet the threshold established by the Illinois Plumbing Code for these specific requirements. Keeping the water pressure below the specified optimal level is essential for the longevity and efficiency of plumbing systems, hence the Code stipulates this precaution at 80 p.s.i.
