I'm trying to pump mixed saltwater from basement about 50 feet, about 8-9 feet vertically, into my first floor sump. Right now I'm using a 1/4 line (interior dimension is smaller than that, of course), and am considering putting a 3/8" line (that's got a 1/4" interior dimension). Trying to figure out if that's big enough to stop the line from "hammering".
