Do you have any problems with the water lines heating up in the sun? I use some PE lines to run water but haven't hooked them up to a valve directly to the stock tank because the black lines heat up so much in the sun. I have to turn on the water and run them for a few minutes before the water cools down enough to fill tanks.
It certainly does get a bit warm. The cows drink the water down fast enough that it’s not a huge concern and once the grass covers it the issue disappears for the most part.
