Review: Good valve, just stopped working after 2 years - 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: Works as designed - I tried 3 different check valves and this is the only one that worked properly.
