I'm not sure if I'm posting this to the right place but...
My sump pump pumps water from my basement to the street in front of my house. When the weather is warm the water flows down the street to the sewer a few houses down from me. But during the winter the water freezes before reaching the sewer resulting in a large ice patch that grows each time more water is pumped out. Is there something I can do to prevent the freezing? Perhaps something I can add to the water in the sump pump well that will not damage the pump?
Thanks.
