Genuine Baxi 5114692 10-Litre Expansion Vessel – Original Plain Boxed Part

Restore consistent and safe pressure to your central heating system with the Genuine Baxi 5114692 10-Litre Expansion Vessel. This vital component is designed to absorb the excess volume created as water expands when heated, protecting your boiler's internal parts and pipework from dangerous pressure spikes.

If your boiler is frequently losing pressure, requiring constant manual top-ups, or discharging water from the pressure relief valve (PRV), a failed or depressurized expansion vessel is often the cause. Replacing it with this brand new, authentic manufacturer spare ensures precise system compatibility and reliable, long-lasting performance.

Supplied brand new in original plain protective packaging, this 10L Baxi vessel is the trusted choice for a professional standard repair.
