UPVC True Union Swing Check Valve - 1" Slip Swing Full Port Utility Check Valve for Backflow Prevention

Smooth, Reliable, and Built to Last – The Perfect Check Valve!I recently installed this 3/4" True Union Check Valve on my aquarium return lines, and I couldn't be happier with its performance. The build quality is top-notch, ensuring a tight seal and smooth operation without any backflow issues. The true union design makes maintenance a breeze, allowing for easy removal and cleaning when needed.It operates quietly and efficiently, giving me peace of mind that my system is protected. Whether for plumbing, irrigation, or an aquarium setup, this valve is a solid investment. Highly recommended for anyone needing durability, reliability, and easy installation!

Have one on each of the returns on my aquarium. I have not had to clean, but I am sure eventually i will, and these make it easy. Being clear also lets you inspect without disassembly.

Wanted to use it in an A/C condensate line in a 2 story condo to prevent backup in the 1st floor A/C unit in case of blockage at ground level. It will NOT work in the vertical position because the check does not float. It should work in a pressure line. It will work in the horizontal position as a swing check. It appears to be well made and can be disassembled for cleaning.

Really good material and it works perfectly!

Exactly as described

Valve just stayed open, flooded my floor when I put my pump into feed modeThere’s no spring to help it close the back flow was enough to keepIt openGarbage

Not sure if they were intended for super low pressure, like water simply trickling along the hose, more or less gravity fed. This just is not great for that kind of application, in case anyone is wondering. The valve just needs a tad more pressure to close and I am sure it's great for that, so purchase according to your need.

Needed these for an 8ft salt water tank . The check valves work excellent
