The Fiamma A20 Expansion Tank is designed to improve the performance and comfort of your motorhome or caravan water system by eliminating the pulsating effect often experienced with pressure pumps. Restyled for 2026!

By stabilising the flow, it delivers a smooth, continuous stream of water rather than short bursts, making everyday tasks like washing and showering noticeably easier.

Its internal diaphragm helps absorb water hammer, reducing strain on pipes and minimising the risk of damage to the pump or fittings over time. This consistent flow also supports more efficient water use, which is ideal for touring and off-grid stays. Compatible with all Fiamma pumps.

Note: this expansion tank replaces 02478-02-.
