Worcester 8716122007 SIT Gas Valve (Pre-Owned) – Greenstar 8000 Life Style

Description

Product Overview

The Worcester 8716122007 SIT Gas Valve is a key component in the Worcester Greenstar boiler range, responsible for controlling the flow of gas to the burner during every heating and hot water cycle. When this valve fails — whether due to internal wear, a faulty solenoid, or seized components — the boiler will typically fail to fire, shut down on a gas pressure fault, or display a lockout error code.

This listing is for a pre-owned Worcester 8716122007 SIT Gas Valve. Pre-owned parts are an excellent cost-effective alternative to buying new, particularly for older boiler models where the repair cost needs to be weighed against full replacement. This valve has been removed from a working or decommissioned appliance and is available for fast UK dispatch.

Please note: As a pre-owned part, this valve should be installed and tested by a Gas Safe registered engineer to confirm correct operation before the appliance is returned to service.

Installation Notes

This gas valve must be installed by a Gas Safe registered engineer. Gas valve replacement involves disconnecting the gas supply, removing the existing valve, fitting the replacement, and conducting a full gas tightness test before recommissioning the boiler. Always consult the relevant Worcester installation and service manual for your specific model. As this is a pre-owned component, the engineer should carry out a full operational test — including checking gas rate, inlet pressure, and valve response — before returning the appliance to service. Worcester service documentation is available from Worcester Bosch’s technical support library.
