Turns out it was my old check valve that was bad. The install was easy (basic PVC cutting and gluing) and it comes with PVC attachments that let you unscrew out the valve if needed. This might be handy if I have to replace someday -- can just screw another one in without having to cut or glue.
This valve lets huge amounts of flow through, and best of all it is COMPLETELY quiet. If I have problems in the future then being able to see the water flow will let me know if water is flowing to help with the diagnosis. No more water hammer when it shuts off, you don't hear it at all. Why didn't I buy this years ago?
I've had it installed for about a month, so I can't yet speak to it's longevity but I see no reason it shouldn't last a long time. Completely satisfied.
UPDATE - 15 months later and working perfectly. It's one of those things that you 'enjoy' every time it works. Sounds silly for a check flow valve but it's quiet and works so well. If you need a valve you must buy this. I paid full price for mine and have no relationship with the manufacturer!
After installing the valve, I noticed weeping from the top thread. After tightening a little more, the weeping was still present, so I took off the valve to investigate. In the attached pictures you can see that the molding marks on the valve were not allowing the o-ring to seat properly. I ended up sanding down the valve ends to ensure that they were flat. To do this I used 800 grit paper in a flat surface, moving in a figure 8 motion. Once I had completed the sanding I reinstalled and have no issues.
So, before installation, check the valve ends to ensure the o-ring will seat correctly.
Having said that, THIS PARTICULAR CHECK VALVE IS AMAZING! You can stand right next to this with your eyes closed while water is pumping through it and only hear the swoosh of the water. And when the valve closes, you can't hear a thing except the swoosh of the water stop. Ultra quiet, no more banging and shaking of the pipe. I was literally speechless after seeing how this performed!
But it's not perfect. As other reviewers have stated, the mating surfaces on the ends of the body, where the O-rings seal, had a ridge from the mold it was made from. Taking no chances, I sanded both ends smooth, using fine sandpaper on top of a flat granite surface plate. While holding the body end perfectly flat on the sandpaper, it took 20 or so strokes across and around the plate to completely remove the ridge on each end.
Also, the threads were not real smooth either. Upon tightening, it felt tight, but then when I gave it just a bit more torque, it would break free and spin loosely for about 1/8 turn until finally tightening again. It was like it had to jump past those mold lines in the threads.
If I were the manufacturer, I would, at very least, remove the ridges on the O-ring mating surfaces. This critical surface should have ZERO ridges. I would pay another couple bucks for whatever machining process they would need to do in production, to avoid having to do this at home.
