Pentair SWG Union

[midlifecrisis]

Does anyone happen to know if a regular FPT 2" union will work to replace the unions that come with the IC series SWGs and will it work (o'ring line up, etc...)? Looking at this one

I have one that has developed a leak at the joint (likely because of a crappy prime/cement job) and I don't have room to cut out the joint. I need to cut out the bad section and use a new side of the union. Only need one. I might try some pipe epoxy but I have never had good results with it and will have to replace it at some point anyway.

Or better question is does anyone know where I can get just one Pentair union?

Thank you, I found that part number while searching. I guess I can put the second one in a bucket with all my other orphaned fittings only to forget I have it when I order another one. I can't be the only one with that problem, right?

I actually used some JB Weld PVC epoxy I had and it is working, so at least it isn't urgent anymore. Meanwhile, the SWG is a dream come true!

Pentair uses a “proprietary” thread pitch because, I was told, field techs don’t like to have to turn the union so many times. It’s honestly silly but that’s how Pentair rolls and then they get to charge you 10X the price of a standard union for their special union.

I made three attempts at finding them on Amazon. These are the only ones that worked.

Do yourself a favor, before gluing any union onto the pipe make sure they thread onto the SWG. That will avoid a lot of nasty words and heartache.

My mom once told me if I don't have anything good to say, don't say it all. That's where I'm at...

Agreed. Words of wisdom. You plumb...

And thanks. I will try those.
