FibroPool Swimming Pool Check Valve - 1 1/2 Inch - Positive Seal & Non Lube Replacement Valve for Pools and Spas

The FibroPool Check Valve has been a great addition to my pool system. It was easy to install, fits snugly, and works exactly as advertised—no backflow, no leaks, and peace of mind when the pump shuts off. The clear housing is a nice bonus so I can see what’s going on without disassembling anything. It feels sturdy and well-constructed, definitely not cheap plastic. If you're maintaining your pool yourself, this is a solid, dependable piece of hardware you’ll be glad you have.

quality PVC and no leaks after install. I believe there was a video where someone tested the device in a sink with water from the faucet to demonstrate that the device did not operate properly. This device requires a bit of back pressure to fully seal the check valve. When tested with a little bit of pressure, the check valve performs as expected.

Good quality. Works as it should.

Well made and good price against branded items

Work well, keep chlorine water from back washing into pump. The transparent top cover is also good for a visual confirmation it's functioning correctly!

Installed for spa back flow- valve fluttered some and still leaked. Company sent out a replacement- adjusted spring a bit and now works great. Great customer service!

Awesome check valve and you will notice I have the Fibropool 3-way diverter valve hooked up there as well. Fibropool makes incredibly durable products and their customer service is unmatched. Great products, great quality, great company!

Needed the 1-1/2" and it works great!
