: We've had it installed for three days and it works.
: Water gets very hot inside if not installed in the shade, lots of shade
We bought $40 worth of tube insulation to put on our white water hose and the water still gets hot. My husband plans on burying the water hose but we don't have a place in the shade for the fountain so right now I've got an umbrella over it. It's very windy here on the coast of Texas so that's not a complete solution to keep it cool. I've been putting frozen bottles of water in the top but they melt really fast and need replaced. It works great, it's just the heat here that's causing us problems. It won't get cool here until November/December unless we have an early winter. I can't put the fountain in my coop due to the wood floor and I don't have the space for it. We don't have a run, our chickens free range on 1/2 acre fenced yard. I'm not disappointed in the fountain because it's working so far but my chickens need lots of cool water to drink and this has not been a good solution for us.
Update:
We put double and triple pipe insulation around the garden hose and then around the fountain. That helped and then the chickens started eating the insulation on the fountain so I wrapped the insulation on the fountain with white cloth. All that with adding a frozen water bottle each day has helped reduced the water temperature. I also keep an umbrella over it during the day. We're in the middle of a heat wave but when we get some rain and the ground gets soft, we'll bury the water hose.
