This Hanicks Ariston Water Heater Expansion Vessel & Non Return Valve Kit (MPN: 406801) is designed for owners of Andris / Europrisma water heaters who want to maintain system integrity and prevent pressure-related issues. Its key benefit is preventing pressure build-up and hot water backflow, ensuring safer and more efficient operation. A potential caveat is that it is specifically designed for the Ariston water heater range.

The expansion vessel absorbs the increased volume of water when it heats up, preventing excess pressure from building in the hot water system.
The non-return valve prevents hot water from flowing backward into the cold water supply, ensuring water safety and preventing contamination.
This kit is suitable for the Ariston Andris and Europrisma water heater ranges.
No, the available colors (White, Blue, Grey) are purely aesthetic and do not impact the performance or functionality of the expansion vessel and non-return valve.
Installation should be performed by a qualified professional (plumber or heating engineer) to ensure safety and correct operation.
It is advisable to check your system pressure periodically, especially if you have a pressure gauge. Consult your water heater's manual for recommended pressure ranges.
If you notice any leaks around the expansion vessel, non-return valve, or associated pipework, turn off the water supply immediately and contact a qualified professional.
Ensure the expansion vessel is correctly installed and pre-charged to the appropriate pressure. Check the non-return valve for proper function. Consult a professional if the issue persists.
The non-return valve may be faulty or installed incorrectly. Inspect the valve and its orientation. A professional assessment is recommended.
While not directly related to heating, excessive pressure could indirectly affect performance. Ensure system pressure is within normal limits as managed by the expansion vessel.
Compatibility: This kit is specifically designed for use with Ariston water heater models, including the Andris and Europrisma ranges. Ensure your model is compatible before purchase.
Installation: Installation should be performed by a qualified plumber or heating engineer. Improper installation can lead to system damage or safety hazards. The expansion vessel needs to be correctly pre-charged with air pressure, and the non-return valve must be oriented correctly within the system.
Care: This product requires minimal user care. Periodically check the system pressure gauge (if available) for any unusual fluctuations. The components are generally maintenance-free under normal operating conditions. If you notice any leaks or unusual noises from the system, consult a professional.
