Short Product Summary
The Fiamma A20 Expansion Tank fits into a caravan or motorhome water line to smooth out an uneven pump delivery. It softens surges and hammering in the pipework, so taps and showers run at a steadier flow.
Why This Product
A caravan or motorhome water pump that pulses on and off can leave taps running unevenly and puts extra strain on the pump and boiler over time. Fitting this tank ahead of the outlet turns that surge into a steady flow, and because its internal diaphragm can be opened up for a check or a repair, it stays a serviceable part rather than something you throw away once it's charged and connected into the line.
Key Features
- Inline diaphragm tank – smooths pulsing pump delivery into a steadier flow
- Works across pump brands – suits Fiamma pumps as well as other common makes such as Shurflo and Flojet
- Removable service diaphragm – opens up for a repair or check instead of a full replacement
- Pre-charged and adjustable – arrives ready to fit, with a valve for recharging using a standard compressor
- Cuts hammering in the line – eases strain on the pump and boiler over time
Ideal For
- Caravan and motorhome owners with a noisy pump wanting a steadier flow at the tap
- Owners running an older pump setup looking for an add-on that reduces surge and wear
- Anyone fitting a new water pump who wants to protect it and the boiler from day one
