Understanding Boiler Pressure Loss
A healthy Baxi boiler should maintain steady water pressure so it can circulate hot water effectively. If the pressure keeps dropping, your central heating and hot water performance will suffer. You might see an error code, lukewarm radiators, or find yourself constantly topping up the pressure via the filling loop.Low boiler pressure is nearly always a sign that water is escaping somewhere in the system.
Common Reasons a Baxi Boiler Loses Pressure
- Leaking Diverter Valve Cartridge
The diverter valve directs hot water to your taps or radiators. If the internal cartridge leaks, water will escape from the boiler, steadily reducing system pressure. - Faulty Auto Air Vent
Designed to release trapped air, an auto air vent can sometimes drip water instead. This is a slow but common cause of pressure loss in Baxi boilers. - Pressure Relief Valve (PRV) Problems
The PRV is a safety device that releases water if the system is over-pressurised. If it becomes worn or blocked with debris, it may leak constantly, leading to low pressure. - Hidden Pipe Leaks
Pipework under floors, behind walls, or in loft spaces can develop small leaks. These are often invisible but will gradually drain your heating system. - Radiator Leaks
Rust, corrosion, or accidental damage to a radiator can cause drips and puddles — another cause of low boiler pressure. - Internal Boiler Component Leaks
Over time, seals, joints, and other components inside your boiler can wear out, allowing water to escape.
