Lol, I AM one step down from an engineer and I think I have a solution to this problem that I will be trying out when I do my pigeon loft. They WERE right about needing an airlock in the container. That said, my idea is as follows: Top container contains the water and has an air tight sealing lid on it, then pipe or hose leading out of bottom of container with a ball valve in it and then leading to the water pan. You would close the ball valve between the water container and the water pan, then open the lid to the water container and refil, close the lid, then open the valve back up. That way you can fill from the top and not lose all of your water.Now...about those plastic automatic water dispenser thingies....I'm not an engineer but I have stayed at a Holiday Inn Express a few times... Why in the name of God's green Earth did they not just put the dang fill hole on the top of the freakin' dispenser????
What purpose...does the fill hole on the bottom serve? Why the need to have to flip the darn thing upside down to fill it????
Oh....and while I'm on a "female dog" fest...why have only an 18" cord????
Needless to say...after soaking myself a couple times...I will be revamping that dang thing to put a fill plug on the top...where it stinkin' belongs!![]()
