Pressure rising while the heating runs is normal thermal expansion. Pressure falling while the heating is off and the system is cold is the pattern that actually points to a fault.
Water spraying, pooling near electrics, or dropping your boiler's pressure fast is urgent. A slow drip from a joint usually isn't. Here's how to tell the difference and what to do about each.
Every major boiler brand signals low pressure differently on the display, but the safe first step is nearly always the same: re-pressurise via the filling loop. Here's what to check per brand, and when to stop.
Over-filling, a weeping filling-loop valve, or a faulty expansion vessel are the usual reasons boiler pressure creeps too high — here's how to bring it down safely, and when to stop trying yourself.
Low boiler pressure is usually fixed with the filling loop — here's the safe, numbered procedure, the safety points to follow, and the clear signs it's time to stop and call an engineer instead.
If you've checked every joint and radiator and still can't find a leak, the water is probably escaping somewhere you can't see — inside the expansion vessel, through a weeping air vent, or along pipework hidden under a floor.
If your boiler pressure keeps dropping, it's usually one of three things — a small leak, a failing expansion vessel, or a passing pressure relief valve. Here's how to tell.
