Surrey Flange – Hot Water Cylinder Draw-Off Fitting

The Surrey Flange is a specialist plumbing fitting designed to allow the draw-off of hot water from the top of a vented hot water cylinder without interrupting the primary flow. Widely used in traditional open-vented heating systems, the Surrey Flange enables the connection of a shower pump or secondary hot water circuit directly to the cylinder, ensuring a strong and consistent flow of hot water throughout the property.

An essential component in gravity-fed and vented plumbing systems, the Surrey Flange is the preferred solution for heating engineers and plumbers looking to boost shower performance or add secondary hot water outlets without compromising system pressure or cylinder integrity.

What Is a Surrey Flange Used For?

• Connecting a shower pump to boost hot water pressure in gravity-fed systems
• Providing a secondary hot water supply to additional outlets or circuits
• Ensuring air-free water draw-off from the top of the cylinder, preventing pump cavitation
• Maintaining system integrity in open-vented copper cylinder installations
