What is the entering water pressure in a residential property?

  1. 10-20 psi

  2. 30-40 psi

  3. 50-60 psi

  4. 70-80 psi

The correct answer is: 50-60 psi

The entering water pressure in a residential property can vary depending on several factors, such as the location and type of property. However, in most cases, it typically ranges from 50-60 psi (pounds per square inch). Options A, B, and D are incorrect because they either fall below or above the typical range, which could lead to inadequate water flow or potential damage to the property's plumbing system. It's important to regularly check and maintain the water pressure in a residential property to ensure it falls within the recommended range.
