These fit my Dine-a-Chook drinkers
"These fit my Dine-a-Chook drinkers and are significantly cheaper than the original replacements, however they are slow to fill and only self-fill to about 10mm. If you hold the float down with your finger, they'll fill higher, but my chickens haven't figured out how to do that :D So there's often a sludgy mess that needs cleaning out. If you've got money to burn, buy the originals but if you're economising like I am, these will do the job but require more maintenance."
