I had a pipe to my skimmer shatter over the winter and I'm building a new one. It has what I think is half of a schedule 80 union on one end of it. There are no markings on it at all except a "3" on the nut, which I assume means the nut is 3". It's on 1.5" PVC.
It attaches to the other side of the union, on my return that then goes underground. I could try and remove the fitting on the underground return, but it's on more than hand tight and I don't want to risk breaking it or the return pipe.
The two pool stores near me were no help, but I think I found the part I need online. Can anyone confirm that the part in this link attaches to a 1.5" PVC and has a 3" nut? No one seems to list the nut sizes and some googling around can't seem to find an explanation anywhere.
The new part: Spears 857 Series PVC Pipe Fitting, Union with Viton O-Ring, Schedule 80, 1-1/2 Scientific
The old fitting(s):
