I only needed the rubber diaphragm assembly (water was shooting out the middle weep hole of my backflow valve) - the diaphragm in this kit fixed the problem for me. I believe the main culprit was just the o-ring on the original diaphragm stem but I needed a quick fix.The holes in the diaphragm did not align perfectly with the valve body (-1 star), but it's close enough to be workable.

This product didn’t fix the leaks as shown, still leaked after installing new parts. Had to order whole new back flow.

No matter how many times I swap out the parts, my backflow preventer just keeps on leaking, and the sizing is completely off. The material quality is abysmal, it can't even hold up to regular use! It's driving me crazy!
