Ideal residential potable water delivery systems operate within a specific pressure range. This range, typically measured in pounds per square inch (PSI), balances adequate flow for household tasks with preventing undue stress on plumbing fixtures and appliances. For example, sufficient force is needed to operate multiple fixtures simultaneously or effectively run a sprinkler system, yet excessive force can lead to leaks, burst pipes, and appliance damage.
Maintaining appropriate levels contributes significantly to water conservation efforts, reduces the likelihood of plumbing repairs, and extends the lifespan of appliances like washing machines and dishwashers. Historically, water systems relied on gravity to provide pressure, but modern systems utilize pumps and pressure regulators to achieve and maintain optimal levels. Consistent and correct force ensures efficient water usage and prevents unnecessary wear and tear on home infrastructure.
