Why Do I Have Low or Inconsistent Water Pressure? - Executive Plumbing
Answer from Blake - Executive Plumbing Lincoln, CA
Low or inconsistent water pressure usually comes down to a problem with your pressure reducing valve (PRV). Homes that have very high water pressure often don’t have a PRV at all, while homes that have one installed may experience drops in pressure if the valve is failing. A failing PRV can cause pressure to fluctuate throughout the day, making it hard to shower, run appliances, or use multiple fixtures at once. High water pressure is just as bad—it stresses your pipes and appliances, leading to leaks and premature wear. The solution is to inspect and either adjust or replace the PRV. A professional plumber can test your system’s pressure and recommend the right fix.
Summary:
Water pressure problems are usually tied to the PRV. If it’s failing or missing, pressure becomes too low, too high, or inconsistent. Replacing or adjusting the PRV restores steady water pressure and protects your plumbing system.
