## Description

3/4 inch Check Valve, 3/4 inch Boat Bilge Pump Check Valve, 3/4" in-line one way valve, 3/4" Non Return Valve (1) 3/4 inch Check Valve, prevent the back flow into the circulation pump. (2) 3/4 inch Check Valve for Boat Bilge, prevent the back flow into into the boat bilge. (3) 2 stainless steel hose clamps are available for free.

Review: It worked perfectly for 2 years and then it just stopped. The rubber flapper now gets stuck immediately after taking it apart and blowing through it. Otherwise it's been a great check valve and worked perfectly for my bilge in Salt water. Maybe would last longer in less harsh conditions. I'm going to try the whale brand valve and see how it does. Time will tell.
Review: Not sure if it was supposed to, but it came with 2 valves but only the two clamps (as advertised). I used it on my boats shower/sink bilge drain hose and it does not back up at all, so it works. We'll see how long it lasts.
