I am looking for replacement return jets (inlets) for a IG pool built in 1964. Given it's age, it has some rather interesting plumbing. It's a 16x32 rectangle with only 2 return jets and 1 skimmer. There is no diverter valve to control flow from the skimmer or main drain. Rather, there is a passive connection from the skimmer to the main drain, ie- only 1 line to the pump. I'm trying to find replacement return jets, but I haven't found anything I can mate to the ports in the wall. When I showed the fittings to a local pool guy, he said that he'd "never seen those things before". Can anyone tell me where I can find some fittings for these things?
Here's what I have:
1) The return lines are 1-1/2" in diameter and smooth, i.e.- not threaded.
2) The nozzle is contained in a 2" diameter ball which is held to the faceplate with 3 screws.
Here are a couple of picture to help:
Any suggestions for replacements would be super!
