I have a greenhouse business with 9 hydrants, had 3 replaced with the baker hydrants. One in the greenhouse that has not been heated turns on by itself. After watching it closely, after temps. getting down to the 20's it freezes up a little every time pushing the handle up after several nights it is pushed up enough to turn it on.
The first time I found the problem it had been on for a day or more and washed out under my weed matt. The landscaper came and adjusted many times and said it was draining. I cant keep my greenhouse warm for a frost free hydrant.
Any advice?
