What is the recommended operating pressure for a household water supply system?

The recommended operating pressure for a household water supply system is commonly specified between 50-70 psi. This pressure range is considered optimal for most residential plumbing systems as it provides a balance of adequate flow and pressure for everyday household activities such as bathing, washing dishes, and using multiple fixtures simultaneously.

Maintaining water pressure within this range ensures sufficient force to deliver water efficiently while minimizing potential issues like pipe damage or leaks that can occur when pressure is too high. Additionally, operating within this pressure range helps to prevent excessive wear on fixtures and appliances that rely on the water supply.

In practical application, pressures lower than this range, such as below 50 psi, may result in a weak flow, making it difficult for users to perform simple tasks effectively. Similarly, pressures above 70 psi can put undue stress on plumbing systems, leading to fixture failure or water leaks. Hence, the range of 50-70 psi is carefully recommended for safe and efficient operation of household plumbing systems.
