Boiler Pressure Too High: What It Means
6 August 2026 | Leyton Boilers
Caused by overfilling, a faulty expansion vessel, or a stuck filling loop, high pressure risks water discharge through the PRV. Check the gauge and bleed radiators slightly if instructed in your manual.
Do not continue resetting without understanding why pressure rose. An engineer can test the expansion vessel and safety valves properly.
Our team resolves pressure faults safely across London properties.
