You can change a water pressure regulator by turning its screw or knob. This helps you get the right pressure for your house. Use hvac tools and a pressure gauge to check the pressure. This makes sure your readings are correct. Many homes need to adjust the regulator if pressure drops below 40 psi. You also need to adjust it if pressure goes over 70 psi. High pressure can break water lines, faucets, and appliances. Low pressure makes water flow slow. It can also cause problems for things like washing machines. Always check water pressure before and after you change the regulator. If you see leaks or the regulator does not work, call a professional for help. Products like brass fittings​ and quick connect couplings from Ningbo Tophcool Metal Fittings help keep your water system safe.
