Understanding check valve technology
At its core, a check valve is a mechanical device that permits fluid to flow in one direction while preventing reverse flow. This seemingly simple mechanism carries profound implications, especially in the context of point-of-use water filters. The design typically involves a valve that opens when water flows in the intended direction, and crucially, closes to block any backflow. This prevents the contamination of upstream pipework installations and ensures that water only travels through the filter during intended use.
