Water lines and drain. The wall that my sink is next to was an area that had just a sink. little shaving sink bathroom nook thing. so i had copper hot and cold lines there, with plenty of length to spare. The drain is a floor drain in the basement, i'll just run a 1.50 in pvc line through the wall to it, it's only 8 feet away . The filter is your typical whole house filter with flexible sink lines connecting it all. I'll get some better picks tonight. It's a pain to get all the fittings together - especially sifting through rows of parts bins.
If you have access to a better supply store than I do, like a lowes, Home depot, Menards, i recomend staying away from compression fittings and using JIC. If your using copper lines, that is.
