I've decided to build a fountain as my pool water temp has gotten unreasonably warm to me.
My plan is to simply attach the fountain(s) to 1 or 2 returns.
I unscrewed the scalloped edge that holds the directional eyeball on and removed those 2 pieces. What remains is a short (approx 1/2") of male threaded pipe.
It looks to be approx. 1 1/2" in diameter, but I tried a 1 1/2" female PVC coupler and it would not screw on to it (too small).
Does the male threaded end sticking out of the pool wall measure 1 3/4"? I did not see that size coupling at Home Depot unfortunately.
Once I have that part figured out, is there a recommendation on the diameter of pipe for the fountain, or does it depend on pump size and length of fountain?
Is the goal to keep the filter pressure roughly the same as it is without the fountain?
