What is the minimum pressure at a sillcock?

• A. 5 psi
• B. 10 psi
• C. 15 psi
• D. 20 psi

Answer: (B)

The minimum pressure at a sillcock is set at 10 psi to ensure that the faucet functions properly and can adequately supply water for outdoor uses such as gardening, washing cars, or filling pools. This standard pressure ensures that the water can flow without significant resistance, thereby reducing the likelihood of leaks or insufficient water delivery. Having a minimum pressure of 10 psi allows for a consistent water supply, helping to prevent issues like stagnant water or backflow, which can occur when the pressure is too low. The choice of this specific minimum also reflects a balance between efficiency and practicality, ensuring that the sillcock can sustain typical outdoor demands while still being safe for use.
