  • Boiler losing pressure | Screwfix Community Forum

    May 09, 2021 · And if these both seem ok, then I isolate the CH flow and return and leave it for a day to see if the pressure drops. If it does, it's a boiler problem otherwise it's a pipes/rad problem. The boiler seems to lose pressure when it's on and off. It is a steady constant decline, althoiugh the pressure reading is always higher when the boiler is on.Learn More
