Your water pressure regulator likely needs replacement if you’re experiencing inconsistent pressure throughout your home, pressure that’s too high (over 80 PSI), or pressure that’s too low (under 40 PSI). You might also notice water hammer sounds when you turn faucets off quickly.
Another clear sign is visible damage to the regulator itself, like corrosion or leaking around the unit. Most water pressure regulators last 10-15 years, so if yours is older and you’re having pressure issues, replacement is often the most cost-effective solution.
Testing your water pressure with a simple gauge can give you concrete numbers, but if you’re noticing problems with your daily water use, it’s worth having a professional evaluation.
