Boiler pressure issues require diagnosing why a system is losing pressure, running too high, or fluctuating. Technicians check the expansion vessel charge, test the pressure relief valve, inspect the filling loop and auto-fill valve, and look for hidden leaks in radiators, pipes, and the boiler itself. We use pressure gauges, thermal imaging, and leak detection to find the source rather than just topping up the system. High pressure often points to a failed expansion tank or overfilled system, while low pressure usually means a leak or a faulty pressure sensor. We also verify that the pressure gauge is accurate and that the low-water cutoff and high-limit controls are working. Once the cause is found, we repair or replace the faulty component and restore correct system pressure.
