if the water bottle is dripping there’s something wrong with it or you’re not using it properly
when you fill it up you have to make sure to create a vacuum by turning it spout side down and then spout side up again (you will hear the ball move about and a little air bubble will come up)
if that doesn’t help you can give it a good clean in hot water which can remedy the seal ..
if that doesn’t work you can replace the washer that goes between the bottle and the spout
i these things all don’t work i think you need a new bottle
(added a day or so later cuz i forgot to mention)
i rinse the nozzles every time i refill the bottles at both ends with cold water
if they’re getting bad i deep clean them in hot water with beer line cleaner (i have a beer fridge so it’s handy but clr or something similar that cleans water deposits will work too) and !!!RINSE IT INCREDIBLY WELL!!! you don’t want that stuff in the bun’s water supply
if you have hard water this is doubly important
i use super pet bottles.. they’re made of glass and seem to be the best i’ve found
