Water pressure is one of the most overlooked factors in a plumbing system's long-term durability.
Residential water pressure above roughly 80 psi puts sustained extra stress on pipes, joints, and fixtures, which can accelerate wear and contribute to leaks over time.
A simple gauge, available at most hardware stores, attaches to an outdoor spigot and gives you a quick pressure reading in a couple of minutes.
A properly installed and functioning PRV keeps incoming water pressure in a safe range, protecting the rest of your plumbing system — and its placement matters, since one installed downstream of the actual pressure source may not do its job correctly.
Generally between 40 and 80 psi is considered a healthy range for most residential systems.
Every few years is a reasonable interval, or sooner if you notice pressure-related symptoms like banging pipes or fluctuating flow.
Let's get you a real answer, not more guessing.
