Works great! by TODD RYAN

Comments: Not a very exciting piece of my salt water tank but def a necessity. It does just what its supposed to do, keeps the water from flowing backwards. I've only had it on the tank for a week now but another review mentioned it lasts about 2 years. Yes, I would recommend this product to my friends.

Comments: This is a good product although like anything else in a reef aquarium, maintenance is required. I just replaced one after two years where calcium build up impaired the operation of the swing valve. Yes, I would recommend this product to my friends.

Comments: The check valve is just what I needed. Your technicians were very kind and very helpful. Although you shipped me the wrong size plastic clamps the techs were very apologetic and quick to send me out the correct ones. Yes, I would recommend this product to my friends.
