I have a 25yr old plus pool with 1 1/4 threaded return in the shallow in and looking for an eyeball jet. All the ones available are 1 1/2 threaded. Any ideas on how to add an eyeball with my older thread size? I see 4 screws(?) around the existing return. Can I replace the 1 1/4 with a 1 1/2? Any help is appreciated.
