These leak. Slowly. But a lot. Even after following the installation instructions and tweaking according to the instructions. Some leaked from the threads. Another did not leak from the threads, but from the middle. In a day and a half I had nearly an entire 5 gallon bucket of water leaked onto the floor of my coop. Will definitely go back to the Farm Innovators brand.
Good service, good product, good price xxxxxxxxxxxccccccccxvvvvvv
