The only thing I can think of in the way of a tip is, purchase another pump just to have in the event something happens to the original. This is a solid piece (Osmolator) of equipment IMO, but I have forgotten to refill my reservoir on a few occasions and the pump ran dry which, is something you don't want to happen. Its a pita to get going again. So, I purchased a spare so I can quickly replace the original when and if this happens again. This will allow you the time to repair the original. $23.00 at Marine Depot.
