Nope. If you put it below your DT, make sure you don't normally run it at the full capicity(10g). If you run it at say 6-7 gallons you should be alright. This is because, when your power goes out-your DT will drain H2O from it-into your fuge. Either to the level of your overflow or the level of you return pipe(whichever is lower). Also, do it right and use PVC, not hose. Much safer IMO.
