We moved in to a new house this year and with the help of the fine people here at TFP, our pool is open and waiting for warmer weather. Today's question is about spa return jets. There are two spa pumps plumbed to 8 returns. The returns are threaded, but they're something bigger than 2". I tried a 2" mpt bushing with a 1 1/2" jet and it was still too small. I can't find any jets larger than 1 1/2". Has anyone seen anything like this?
