Question ~ what do you mean tapping the hole, I know what teflon is but not sure of tapping. Photo would be goodI am using a 21/64 drill-bit and tapping the hole. I will seal the threads with Teflon tape. If you do not use a tap, you are mashing the male threads into the non-threaded hole. I know, I know, the manufacturer says it will hold when done this way. But, if the male fitting is threaded, my female hole will be threaded also. Just me....
Almost every nipple waterer system I've seen has puddles of water underneath the nipples. I betcha mine won't have nearly as much. I'm sure the chickens spill some but, my nipples will not leak from the threads.
Old machinists find it hard to give up old habits. But, I have another reason for wanting no leaks. This system is located on the property of an elderly friend of mine who is raising these birds with me. She is hauling water every day for these chickens to drink from the old inverted jar type waterers. She keeps everything sooo neat. I just don't want this watering system to cause the watering area to stay messy. And, I want this lady's work to be cut dramatically.
I will then start work on feeders that holds about 50 pounds of feed and, can be filled from outside of the pens.
