- I mean this comment, if it’s showing on the front panel gauge…this is normal behaviour. Due to cold water entering the boiler, raising the pressure via expansion via heating. As this is a hydraulic effect, even the slightes leakage of water drops the pressure significantly
MetalDave I was under the impression it should maintain a resting pressure of 1-3bars, and wonder if there is an issue with the OPV or another component.
