Product Overview

The Fiamma A20 Expansion Tank Black - 02478-02 is a high-quality pressure stabiliser designed for motorhomes, campervans, and caravans to improve water pump efficiency and performance. By eliminating pump pulsations, it delivers a smooth and continuous water flow while reducing noise and vibration. The internal diaphragm absorbs water hammer, preventing potential damage to pipes and fittings, and helps optimise water usage. Compatible with Fiamma Aqua 8 and Aqua F pumps as well as popular non-Fiamma models such as Shurflo and Flojet, the A20 tank is pre-set at 0.9 bar but can be adjusted to suit different systems using a standard compressor. Easy to dismantle for maintenance, it’s an essential addition to any on-board water system for improved reliability and comfort.
