The DuroPlumb Boiler Filling Loop Straight Type with Full Flow Isolation Valve is designed for controlled pressurisation of sealed central heating systems - it provides a direct connection between the mains water supply and the heating circuit, allowing system pressure to be safely restored when it falls below the boiler’s operating requirements.
This straight-type filling loop incorporates a full flow isolation valve, enabling unrestricted water flow during pressurisation and complete isolation once the correct pressure has been reached, which helps ensure accurate pressure control and supports best practice for sealed system operation.
Design And Specification
Manufactured for domestic central heating applications, the unit features 15mm compression connections and an overall length of 230mm. The straight configuration allows for clean, compact installation with minimal pipework adjustment, making it suitable for boiler replacements, new installations, and system upgrades.
The integrated full flow isolation valve allows the filling loop to be securely closed when not in use, reducing the risk of over-pressurisation and ensuring the system remains isolated from the mains supply outside of topping-up periods.
Intended Application
This filling loop is intended solely for recharging pressure in sealed heating systems. Once pressurisation is complete, the isolation valve should be fully closed in line with standard installation and maintenance procedures.
