Jandy valve connection question

[NovaCurls]

We have a Pentair 6-way valve (model SM2-20-2/SM2-PP2) on our older pool. The backwash port looks like 1.5" threaded to ~2" slip on PVC union. I want to replace this with a NH threaded union for a fire hose that I bought. I know very little about pump pad construction and PVC connections, but it looks like the slip-on union is glued to the valve. Is this likely? If so, is there anyway I can remove it? Or will I have to cut my new fire hose?
Thanks for any input!

It is common to glue directly to a multi-port valve. However if you have a threaded connection present, it should be possible to unscrew the existing threaded connection and then attach an appropriate adapter there.

Whatever the situation actually is, you will need to attach an appropriate adapter, and that is easy enough to do regardless. If you post a photo we can give more specific advice.

Thanks for the reply. I'll snap a picture after work. The current adapter looks like this -
and appears to be glued. If I give it enough muscle, can I removed it if it is glued? If it can't be removed, do I have any other options?

If it is glued you will want to find a pipe size that can be glued to the fitting and then glue the correct adapter to that.

Chances are it is just very tight. It is not common to glue threaded fittings.

I took a closer look after work; what I thought was glue was some kind of caulk. Took a bit of umph, but it came right off. Thanks so much for the advice!
