Yes, it is an inground and I ran a 2" from the main drain to the pad, a 2" from skimmer 2" to pad and 2" from skimmer 1.5" to pad as a backup. Pump will be slightly below level of water. I will have a 3-way connecting skimmer/main drain feeding into pump.
I was thinking of taking the output from the 3-way, feeding it into a 2-way prior to entering pump.
