Completely worth it. By Jason on 11/18/2014

I have 20 or so of the Home Depot check valves, they're cheap and work fine. But... they do go bad. After 15 years with different size aquariums over the years, now with 750g tank, the last thing you want is for something like this to go bad. I have been slowly replacing them with these valves mostly because you can see whats going on. I install them 'flap up' and follow the flow 'arrow' - None have failed. I will say they are a little bulky tho, but imo they are completely worth it.
Good but not perfect By Simply J on 11/3/2014

I'm very pleased with these valves as a fail safe. However if you install them in a vertical position be careful not to drop/lose the O-Rings as they tend to fall out easily. Other then that very good product.

I don't have a million dollars to spend on a check valve at the moment, so I got this one. It did the job, and did it well. Having the union there is pretty nice.
There is one smidge of an issue. There's a very very small leak (allowing a very small drip of backflow). I assume this is because there isn't enough force on the flapper. BUT when you have water above and below the valve, there is enough force from pressure and gravity (creating a vacuum and pulling down on the flapper while water on top pushes it closed) zero leaking in this case.
had vibration but found problem By ayhan on 9/2/2014

I had this vibration problem when sump pump is turned off. I was really [ticked] off.After research I found that problem is caused by pressure from water. I had installed check valve pretty close to sump pump which was mistake. Next day I have changed location of check valve and installed to closer return pipe goes to the tank. I know valve manufacturer didn't design for use fish tanks so I can't blame them for no instruction but BRS should take notes and print out for customers or send warning email about installation.
Terrible By Chris on 5/30/2014

I installed this check valve about a week ago and since then I've tested it many times. Does not work as advertised. The valve for some reason continually opens and closes making a load vibration noise. It only slows the water flow. Maybe it needs more time to wear in.

Didn't work for me By Brad on 11/23/2013

I used the 1 inch version of this valve between my display tank and return pump. The valve worked fine for a few weeks then started acting up when I was shut the pump off for feeding. The flapper would bounce on and off where it was supposed to seat. Not only did this mean it wasn't stopping the siphon from the tank, but also sent vibrations though the pipes and sump. This would continue until I would lift the loc line out of the water to break the siphon. I tried cleaning the valve even though it was not visibly dirty, and that would make it work correctly for about 2 days. I called customer service, they had no other suggestions but offered to send me a new one free. New on came and had the same problem.
I have now switched to the spears true union check valve and it has worked fine for over a month now. I gave the product 2 stars instead of 1 because a friend of mine uses this valve and it has given him no issues. I recommend spending a couple more bucks on the spears valve.

Great Check Valve By Warren on 4/25/2013

Does not interfer with water flow at all like some other check valves. With this being a union, it keeps you from having to add a union and a check valve. Saves space.
