Surrey flange adds a connection for a shower to a hot water cylinder and improves water quality by reducing air content, often solving problems of air locks in shower pumps and power showers.
The flange also ensures an independent hot water supply to a shower at a constant temperature, even when other hot water taps are turned on, allowing showering in comfort.
