The Fill / Pressure-Reducing Valve on Your Lochinvar Boiler

The automatic fill valve (pressure-reducing valve) tops up the heating system from the mains and holds it at the correct fill pressure. A failed fill valve either lets the system lose pressure or overfills it, tripping the relief valve.

On Lochinvar systems — including models such as Knight, Knight WH, Noble — a failing fill / pressure-reducing valve often shows up as ignition lockout or related symptoms. We diagnose it precisely and install the correct genuine Lochinvar part.
