Even after tightening, this item still leaks a lot. So ended up using our old chicken water dish, instead of this new one. (we use this item for our dogs) Since new one kept leaking digs kept digging in the mud created from the leak ):

This was easy to install but difficult to adjust. There is a bolt on the side to adjust the water level. It was originally set to never stop the water flow. Now it stops near the top but every few days it overflows again. Im going to kero trying. It is a great size for my three dogs and I love the stainless steel.

Keeps plenty of water for my active German Shepherd Belgian Malinois
