The Pressure Relief Valve on Your Navien Boiler

The pressure relief valve (PRV / safety valve) is a critical safety device that opens to release water if system pressure rises to an unsafe level, preventing a dangerous boiler over-pressure. A weeping or stuck PRV must be addressed promptly and never plugged.

On Navien systems — including models such as NCB-240E, NCB-210E, NHB-150 — a failing pressure relief valve often shows up as e003 ignition failure or related symptoms. We diagnose it precisely and install the correct genuine Navien part.
