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.

It will work.
So I use this for a dwc setup with recirculating water. If the power goes out my rez will overflow. I got this thinking it would stop the flow back with out power. Nope it didn't stop it. It did however slow the backlog greatly. I might have a defective one I'm not sure. Only to find out is to order another one. But if you are looking for 0 flowback this might not work fyi
