Well the valve is rebuilt – kind of. I did not think to mark the handle position relative to the baffle and so it’s now backwards.

It functions perfectly but backwash is now filter.

Oh well, I need to take it apart again anyway. When I went to the parts place I missed to cover o-ring.

It was pretty easy to do. I only had to put the handle and stem assembly in a vise so to hammer out the handle pin with a drift pin. Reassembly required the vise and the death grip to get the pin back in but all in all it was not too bad.

But, the valve is still just as noisy as before. I am thinking the pump may be oversized. Too much flow for the valve. I can feel vibrations when I touch the valve and the noise sounds like, well, too much water being forced thru a valve. I wrapped it with a wet bed sheet that I use to catch old DE, and that dampened some of the high frequency noise.

So the saga continues.
