The normal house water pressure in most residential areas typically falls within the range of 40 to 60 pounds per square inch (psi). However, specific water pressure can vary depending on your location and the municipal water supply system. It's crucial to maintain water pressure within this range to ensure the proper functioning of plumbing fixtures and appliances. If your water pressure is consistently above or below this range, you may need to install a pressure regulator or address any issues with your plumbing system to avoid potential damage or inconvenience.
