Comments: Good product, does what it is supposed to do. Only problem is that the o-ring seal on the true union is on the opposite end of the true unions you can at the hardware store. Thus if you want to move this valve to another location you would have to get the true unions from the manufacture, SPEARS I think in this case, instead of your local hardware store. Yes, I would recommend this product to my friends.

Comments: I've used this product before on the siphon line below my 54 gallon tank. It has always performed as expected. We are sometime subject to power failures at my office where the tank is located and I rest easy knowing that I won't come to work and find a flooded floor dried out fish. Yes, I would recommend this product to my friends.

Outstanding check valve by Bill Russell

Experience Level: Expert

Posted on 7/13/2009 from SMYRNA, GA UNITED STATES

Comments: I purchased 3/4" slip check valve to prevent back flow back into my sump. There appears to be minimal pressure loss and it's see through so the water flow and flapper are visible. No leaks through the threaded union either. Though it's a little pricy (3x-4x vs. HomeDepot)I would highly recommend the valve Yes, I would recommend this product to my friends.

Works well by Laird

Comments: Nice valve. The flapper seats securely with no head and requires very little pressure to open. As the flapper moves out of the flow path there is very little resistance unlike with most spring loaded valves. As it is clear, it is very easy to see any obstructions (snails, macroalgae). My only concern is how long the rubber flapper will last in saltwater. I can't find any information on if replacements flappers are available. Yes, I would recommend this product to my friends.

Comments: The one inch is very BIG but, plums in with no problems. Great way to stop back flow into your sump. NOTE: If your pushing alot of water into the overflow box and you have the ash tray effect"UUUUUUUU" at the top of the over flow box. You will still get some back flow to the sump from the over flow untill it levels out below the U on your over flow box..... Yes, I would recommend this product to my friends.

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

Experience Level: Beginner

Posted on 1/9/2008 from LAS VEGAS, NV UNITED STATES

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

Experience Level: Intermediate

Posted on 12/27/2007 from Michigan

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.

Comments: Great Product!!! I own 2 of these now. Wouldn't go any other way for a large capacity check valve. Very sound construction and easy to maintain. Check valve completly seperates from system for maintenance cleaning. Yes, I would recommend this product to my friends.

union check valve by GENE YATCHYSHYN

Experience Level: Intermediate

Posted on 8/5/2007 from EAGLE RIVER, AK UNITED STATES

Comments: The union check valve is great. It allowed me to get my tank up and running with no worries about water draining out of my pump, so when start-up after a power outage I don't worry about a dry pump. The only thing that I dislike about the check valve is that it is very big and bulky. Other than that it is a great idea Yes, I would recommend this product to my friends.
