I have a Sealife Systems sump (was given to me so I don't know much about it) that has a male, threaded output (to pump). I got a female threaded 1" PVC
but that's too small. A 1-1/4" female threaded PVC
is too big. So it's not a common PVC
size. Maybe 1-1/8" but I haven't seen that at HD
. Anyone have a clue? Thanks!
