I need to put in 5 winter watering sites and would like some advise as to the the type of tanks/troughs/bowls you like. The line feeding the trough is a pressurized pipeline, but there is not power. I like simple, dependable, cheap and reliable.
I currently have two thermosink bowls and have had decent luck with them. They have to be pumped out when not in use.
Looking for other experiences and types.
