Push/pull backwash valve leaking, tutorial on O-ring replacement?

[ShinDiors]

Cannot tell if it is a hayward or pentair, but it is an old typical push/pull backwash valve. A month ago I did a backwash myself for the first time, today noticed water puddling on the bottom of the plunge. Read a few threads and talked about having to replace the o-ring. Can anyone direct me to some tutorial (or video) on how to tear apart that valve and replace the oring?

Thanks a lot.

DE filter itself is PAC-FAB NS48, so does that mean it should be using a pentair valve? How can I tell about the model number of push/pull valve?
