What is the typical PSI range for residential water supply systems?

• A. 30 to 50 PSI
• B. 40 to 60 PSI
• C. 40 to 80 PSI
• D. 60 to 100 PSI

Answer: (C)

The typical PSI range for residential water supply systems is commonly accepted to be between 40 to 80 PSI. This range strikes a balance between providing sufficient water pressure for household use while also maintaining the integrity of plumbing fixtures and appliances. In this range, homeowners can expect adequate pressure for normal activities such as showering, washing dishes, and utilizing other plumbing fixtures without experiencing issues like weak flow or pressure fluctuations. Lower pressures, such as those below 40 PSI, may result in insufficient flow rates and poor performance of appliances. Conversely, pressures exceeding 80 PSI can lead to excessive wear on plumbing components, increased risk of leaks, and potential damage to fixtures and appliances. Understanding this typical range helps plumbers and homeowners alike manage their water supply systems effectively, ensuring both functionality and longevity of the plumbing infrastructure.
