Hayward VS pump was installed at the beginning of the summer with some new plumbing. Im trying to seperate this union but it wont budge. I dont know what it looks like on the inside (meaning if it is some type of slip fit connection or mearly pressed together with a o-ring) but I cant seperate it. Any suggestions?

Antony,

If it's close coupled on both sides you may need to loosen the pump mounting so it can slide away. All that's there is a flat mating surface on both sides and one has a grove with an o-ring.

I'm away from the pump right now and haven't fully winterized it yet. Does the top pipe likely have some type of o-ring in there or are both services supposed to be smooth and just sit flush together?

I know I have to get that glue off so I'm guessing some light sanding would be the best option?
 
The top part has an O-ring. I would probably scrape the surfaces smooth with a razor knife. Sanding can work as long as you can get the surfaces smooth enough. Maybe use several different sandpaper grits and work down to a super fine grit to polish the surface smooth.
