Check valves for water filters
The check valves from John Guest® are required when you want to prevent liquid backflow. The valves are very safe and reliable due to the use of a stainless steel spring mechanism. The check valves are connected with the John Guest® Speedfit system, which leads to easy and fast installation.
All John Guest® pipe fittings used for the VISION AQUA® water filters are suitable and approved for use in food, drinking water applications, and water treatment.
