What is one of the benefits of addressing high water pressure in a building?

1. Decreased installation costs

2. Extended lifespan of plumbing systems

3. Increased response times for leaks

4. Fewer inspections needed

The correct answer is: Extended lifespan of plumbing systems

Addressing high water pressure in a building provides the benefit of extending the lifespan of plumbing systems. High water pressure can lead to significant stress on pipes, fittings, and fixtures. Over time, this pressure may cause wear and tear, leading to leaks or even catastrophic failures in the plumbing system. By mitigating high water pressure, the plumbing components experience less strain, reducing the likelihood of damage and repairs, which can necessitate premature replacement. This proactive approach not only helps in maintaining the integrity of the plumbing but also contributes to the overall efficiency and reliability of the building’s water supply infrastructure. The other options may appear plausible at first glance but do not address the primary concern regarding high water pressure. For example, while adjusting water pressure could potentially lead to some initial installation cost savings, it does not fundamentally change the long-term costs associated with plumbing maintenance or repairs. Similarly, while managing leaks is important, addressing water pressure does not inherently improve response times. Lastly, while fewer inspections might seem appealing, the need for consistent maintenance and monitoring of plumbing systems to prevent issues from high pressure would likely require regular inspections regardless.
