Genuine Viessmann pressure relief valve, supplied and professionally installed by Technical Safety BC–licensed gas fitters. Never sold for DIY.
The Pressure Relief Valve on Your Viessmann 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 Viessmann systems — including models such as Vitodens 100-W, Vitodens 200-W, Vitodens 050-W — a failing pressure relief valve often shows up as f2 no flame or related symptoms. We diagnose it precisely and install the correct genuine Viessmann part.
