So the measurement is the diameter of the opening (port)? Does Intex have a special type of thread pattern? Should any type of 1.5" collar work?
Thank you so much for taking the time to answer my original question :).
I need to build/hack together a waste hose for my Intext Sand Filter (SF80110-1) which does not come with one. Does anyone know what the collar size of this waste port is.
