I am not a big fan of check valves (CV), but We just got a large shipment of these cool, if not improved check valves. These swing check valves looks similar to the spears CV, but these are really swing CV. As you can see they will actually fully swing for little to no obstruction on the flow. These are all full plastics with the exception to the flapper, we're on the edge are rubber/foam pads. You can either use them as is or, to make them more practical you can put unions on both end for easy disconnect..thought I share, for those setting up there system and looking for CV.
