Description

KeyPlumb Expansion Vessel Mounting Kit

The ZL-4022-3/4 KeyPlumb Expansion Vessel Mounting Kit is a complete installation solution designed to securely mount and manage an expansion vessel within heating or unvented hot water systems.

This kit includes three essential components to ensure safe and efficient system operation. The 3 bar safety valve protects against over-pressurisation by releasing excess pressure when required. The automatic air vent (rated up to 10 bar) removes trapped air from the system, improving circulation and preventing common issues such as noise and reduced efficiency. The pressure gauge provides clear, real-time monitoring of system pressure, helping maintain optimal performance.

Ideal for both new installations and replacements, this kit supports system stability, improves efficiency, and reduces the risk of faults caused by pressure fluctuations or air build-up.
