As such, most water pressure regulators have a screw on top that can be adjusted to increase tension in the innerspring or loosened to allow water to flow freely. We’ll talk more about this when we get into the steps for adjusting the pressure!

The top part of the regulator should have the adjustment screw and the lock nut. The former raises and lowers the water pressure, but before you can adjust it, the lock nut must be loosened first. Turn the wrench in a counter-clockwise direction to loosen the nut. Be careful not to turn it too far, however.
