Hi-
Question from an amateur/DIY - we had a sump pump installed at the bottom of a stairwell, to prevent rare basement flooding with torrential rain. What is the best way to deal with winter/freezing temperatures? The pit itself is probably 6-7' below ground level, and the pipe outflow is open/exposed, ultimately connecting with a patio drainage system (see attached pics). My two concerns were water in the pit freezing and water in the pipe freezing. A simple solution might be a temperature regulated outlet, turning the pump off below 35 (?) degrees? But that might be a problem if temperatures quickly rises, before the ice could melt? Another possibility I thought of was some sort of warming cable for the pit (bird bath etc?) and a heat wrap for the pipe?

Is any of that even necessary, or is there a better solution someone can suggest?

Thank you!
