The Zip Water AQ2 expansion vessel and check valve is an essential accessory for any Zip Aquapoint water heater installation with cold water draw-off points nearby. It comprises a 2-litre expansion vessel and check valve, which manages hot water expansion to prevent issues and damage.
The expansion vessel's key role is absorbing expanded water from the heated cylinder. As water is heated, it expands in volume, increasing pressure in the closed system. Without an expansion vessel, this can cause water to backflow into cold water outlets.
The 2 litre tank in this Zip kit provides sufficient capacity to accommodate expanded hot water from a typical small Aquapoint heater, protecting the system from excess pressure build-up. The vessel is made of corrosion-resistant materials suitable for potable water systems.
This kit also includes a check valve designed to regulate water pressure. Pre-set to limit pressure to under 4 bar, it protects the heater cylinder and plumbing from damage from high-pressure surges.
The check valve only allows one-way flow, preventing expanded hot water from moving to other outlets. This combined functionality regulates system pressure, reducing wear on components. The valve has 15mm BSP connections for straightforward installation.
With its expansion tank and intake valve, the AQ2 expansion vessel and check valve enables the safe, efficient operation of an Aquapoint hot water system. By managing water expansion and pressure, it prevents potential damage and disruption. This genuine Zip Water spare part kit delivers reliable performance.
