To improve water pressure in your kitchen or bathroom, check the faucets’ aerators, as they can become clogged with mineral deposits. Consider cleaning or replacing them if necessary. Additionally, check the shut-off valve to ensure it’s open fully. If these steps don’t help, consult a plumber to examine the pressure regulator, pipes, and any potential obstructions that may be affecting water flow. They can identify and address issues to restore optimal water pressure in your kitchen and bathroom.
