Installation was easy. removed the old compression check valve system and put this in. There was no pipe cutting involved , but if you do the way this one is built makes it easy to put on each end of the pipe.

This valve replacement made my pipes go from seeming like they're going to rip off the walls and ceilings, to not really shaking at all. It's like magic! The difference was incredible!

The check valve operation that is so quiet that in order to hear it you have to be standing within a few feet of it, and you also need to be looking at it in order to be sure that it actually was operating. If there's any background noise, then you won't hear this new valve at all. The loudest part is actually the sound of the pump running, which is also quiet in this case by the way. If you don't hear the faint noise of the pump running, then you will not likely hear the valve at all.
