Boiler Pressure Dropping? Get Specialist Help
A boiler that consistently loses pressure cannot operate correctly and may shut down entirely. Pressure loss typically indicates a leak or a failed expansion vessel.
Why Boilers Lose Pressure
Common causes include a leak in the system pipework (hidden behind walls or under floors), a failed expansion vessel that cannot accommodate water expansion, a faulty pressure relief valve, or system venting issues.
Symptoms of Pressure Loss
The pressure gauge drops into the red zone (below 1 bar), the boiler displays a low-pressure error code, radiators have cold spots, and the system may shut down automatically as a safety precaution.
Diagnosing Pressure Problems
Diagnosing pressure loss requires systematic checking of the entire system. Our technicians use pressure-testing equipment to locate leaks and evaluate the expansion vessel condition.
Safety Reminder
If you smell gas, suspect carbon monoxide or believe there is an immediate danger, leave the property and contact emergency services or the appropriate gas emergency authority. Do not remain inside — exit the building immediately and call for help from outside.
