Inline Check Valve with 1/4-inch Quick Connect Fittings

Inline check valve prevents water from flowing back through the water line. It is used on reverse osmosis systems to prevent backflow through the membrane. When the check valve malfunctions, it can allow the tank to empty back through the membrane and down the drain line. The 1/4-inch quick connect fitting allows the inline check valve to be replaced easier and more quickly then the threaded elbow check valve.
