I have an overflow to be precise constantly running water on my ably. It wasn't a real problem contained by the warm weather but in a minute it's freezing and I'm not sure if it's supposed to do this or not. I wouldn't think that it is supposed to constantly run hose down, is it?
Thank you!
Answers:    Where we live there are more afterwards several artisan wells the flow adjectives the time. Forty below zero and they're flowing, the owners hold to vent them outside the house or get a flood, winter or summer.
Some return systems keep hold of running to prevent the pipes from freezing. If you are concerned, call a in good health company and have them check your switch, most run on pressure constraint. You might have a overrun elsewhere that's why the pump keeps running.
