As the title says I am a new pool owner. The house was a bank repo so I have no history or information about the pool. I did have it inspected and everything restored to proper working order by a local pool company once we took possession. My pool has a vinyl liner and has two return jets on one side and one return on the other. I had to buy new eyeballs and collars for all three jets initially so I know they are 1.5" threaded. I do not know the exact size as I haven't measured it yet.
So, bought a pool fountain from Amazon (Splash-A-Round Pools SEC385 Waterfall Spray Pool Fountain) intending to install it on the "extra" jet. My problem is the fountain has male threads and so does the part coming out of the pool wall. Do I need a coupler or should that male threaded part come out to reveal female threads? I've done some searching on these forums and have seen examples of what my return looks like. But, I'd like to be sure before I go taking things apart and possibly causing me to break something I can't fix myself. TIA for any and all help.
