Surrey Flange

Considered an industry standard, the Surrey flange is designed to provide an independent hot water supply as well as dramatically reduce air surging, noise and temperature variations.
The Surrey flange air vent automatically purges the shower circuit preventing air accumulation in the hot water shower feed (patent applied for).
The vent automatically traps and releases air, preventing back feed of aerated hot water.
The installation of a Surrey flange is recommended for shower pumps up to 3 bar pressure.
