What is the standard pressure range for residential water supply systems?

The standard pressure range for residential water supply systems is 30-60 psi. This range is ideal for ensuring that water flows adequately to various fixtures in a home, including showers, faucets, and appliances. Maintaining water pressure within this range helps prevent issues such as water hammer, leaks, and excessive strain on plumbing fixtures or appliances. Pressures lower than 30 psi can lead to reduced water flow, making it difficult to perform everyday tasks, while pressures exceeding 60 psi could potentially damage plumbing systems and cause leaks. This standard also aligns with guidelines from many plumbing codes and manufacturers to ensure safety and efficiency in residential water supply systems.
