The answer to 'how to maintain pressure regulator' is to regularly inspect and service your home's pressure regulator. A pressure regulator is a critical component that controls the water pressure entering your home, ensuring it doesn't exceed safe levels that could damage plumbing fixtures and appliances.
To maintain your pressure regulator, start by checking it every 1-2 years. Look for any signs of leaks, corrosion, or damage. If the regulator is working properly, the water pressure should be between 40-60 PSI. If the pressure is outside this range, you may need to adjust or replace the regulator. For best results, have a professional plumber service the regulator, as they have the right tools and expertise to do the job correctly.
