CHECK VALVE by KEN

Experience Level: Intermediate

Posted on 2/15/2008 from CHICAGO RIDGE, IL UNITED STATE

Comments: I use this check valve to prevent back flow from my protein skimmer into the sump during a power outage. I have yet to find one of these that still functions after 12 months. The salt water must deteriorate the rubber to the extent that it becomes hard. The "flapper" then does not return to the closed position and allows backflow. This is a completely sealed unit, there is no maintenance or replaceable parts.The good thing is that with this type it is easy to replace because of the union connections. Yes, I would recommend this product to my friends.

Works as advertised by South Bay Photography

Comments: The check valve worked as advertised. Easy to plumb and incorporate into your setup. A little bigger than I thought, but it works fine. Stopped the siphoning and back flow once the pump was turned off. Definitely suggest this for every reef/FOWLR tank setup. Yes, I would recommend this product to my friends.

A Good Choice by Kobayashi_Maru

Comments: I replaced a manual ball valve with this check valve, which I'm using to prevent siphoning back down into the sump. The valve installed very easily, the clear PVC provides a nice view of water flow, and the union allows easy removal of the pump (and of course the valve). The valve is made very well, and looks like it will last a long time. Yes, I would recommend this product to my friends.
