These poultry drinking cups are made of high quality, UV resistant
plastic. The drinker works by way of a float valve: As the cup fills
with water, the
yellow arm starts to float and the supply is shut off. These drinkers
are easy
to clean and provide a consistent supply of fresh water. These can
be attached directly to a heavy base bucket, 20L container or pipe. Ensure its is plastic so it can drilled (using a 8.5/9 mm drill bit) and threaded. The drinker
cup has a tapered thread, so will self-tighten as you thread it onto the
container.
