Teach your birds to drink in the basket. People say "mine are basket trained", but have they spent several days in the basket feeding and drinking? No. Well they're NOT basket trained then. If you train them, you don't need to pump water into them. As well as basket training, I have my loft doors made up with wicker and hang drinkers on the outside just like the fed baskets. The birds don't like sticking their heads out between the bars, but this way they get used to it in the loft.
