Just checking with you Kelseyledare, on which route you too and to see if you got it fixed. I had my threads break off my return jets and I am looking for away to fix my issues. It looks like your returns is larger then mine? 1-1/2?
I have a Pentair FSN-48 (non-plus) in group pool system, even the jet return eyeball are Pentair manufacture. I have been having issues find the correct size eyeball. Please see photo. All the ones I am finding are too big.
