dude, seriously. what could be wrong with the sump? either the tank wasnt water tight or a punp is broken. either way your still getting a baraign. This is the thing with people today.. theyre too scared to but something if it isnt perfect. I bought a £500 guitar off ebay for £80 and its fine. sometimes you take risks, but they pay off. tell him to fill it up though but now necessarily the sump going.
