The BWT BestHead Flex Filter Head is a versatile filter head for BWT water+more cartridges, with a Flex Insert connection system that adjusts in 30° steps for clean, tool-free installation in tight undersink spaces. Whether your supply lines come from the left, right, or straight ahead, you can route hoses neatly without forcing anything or reaching for a spanner.

Built with everyday use in mind, it includes an automatic water stop so you can swap cartridges without turning off your supply or dealing with leaks and an Easy Vent valve makes purging the system simple once the new cartridge is in. Two built-in backflow prevention valves keep your drinking water supply protected and everything is made from food-grade materials rated to 8 bar.
