Product Information
Full details
The Fiamma A20 Expansion Tank is designed for RV owners, boaters, and anyone with a pressure switch water system who experiences pulsating water flow or frequent pump cycling. Its key benefit is providing a smooth, continuous water supply, reducing water hammer, and extending the life of your water pump and other components. A potential caveat is that installation requires basic familiarity with plumbing systems.

Extended Product Information
FAQs
What is the main benefit of the Fiamma A20 Expansion Tank?
The primary benefit is providing a smooth, continuous water flow by eliminating the pulsing and on-off cycling of your water pump, which also reduces wear on pump components.
Will this work with my existing water pump?
Yes, the Fiamma A20 is designed to work with any pressure switch pump and includes 10mm and 13mm fittings for broad compatibility with most caravan and motorhome water systems.
How do I install the expansion tank?
Installation involves connecting the tank inline in your water system, typically after the pump. You'll need basic plumbing tools and familiarity with your vehicle's water system. Ensure power to the pump is off before starting.
Does the tank require maintenance?
No, the Fiamma A20 is designed as a maintenance-free component. Regular checks for leaks at the connection points are recommended.
Can this tank reduce my water usage?
Yes, by providing a steadier flow and reducing unnecessary pump cycles, it helps conserve water compared to a system without an expansion tank.
What is 'water hammer' and does the A20 fix it?
Water hammer is a pressure surge or shockwave in the pipes caused by sudden changes in water flow. The internal diaphragm of the A20 absorbs these shocks, protecting your plumbing system.
Does it affect my water heater?
Yes, by providing a more consistent water flow and preventing rapid pump cycling, it can improve the performance and lifespan of compatible water heaters.
Troubleshooting
Water still pulsing after installation
Ensure the tank is properly oriented (often vertical with the air valve at the top) and that the pump's pressure switch is correctly set. Check for any air leaks in the system before the tank.
Pump cycles very frequently, but not as before
Verify that the tank's internal diaphragm has not been damaged and that the system is holding pressure. Check that the pump's pressure switch is functioning correctly.
Leaking connections
Tighten the fittings. If leaking persists, inspect the O-rings or seals on the fittings and ensure they are properly seated. Use appropriate plumbing tape or sealant if necessary.
No water flow or reduced flow
Check for blockages in the water lines or pump inlet. Ensure the tank is installed correctly inline with the water flow direction.

Setup, Compatibility & Care
Setup:
- Identify a suitable location in your water system, typically after the water pump and before the first outlet.
- Disconnect power to the water pump.
- Drain the water system to relieve pressure.
- Using the provided 10mm or 13mm fittings, connect the A20 expansion tank inline with your existing water lines.
- Ensure all connections are secure to prevent leaks.
- Reconnect power and run the pump, checking for leaks at the connection points.
- Prime the system and test the water flow.

Care:
The expansion tank is a maintenance-free component. No regular cleaning or servicing is required. Periodically check connections for any signs of leakage.
