First year in Knoxville and first year as pool owner. Don't have an automatic freeze system on/off for pump, but have been manually running each day for a couple hours. Forgot to run pump yesterday (temps were mild) and night was down to mid-20's through mid day today where high was 36. When I went to turn on pump today, nothing. Very cold. I got a pot of hot water and opened pump and poured it in, which got things flowing, yay. The pump equipment is alongside the outside of the house, and there is a spigot for a small fountain that would not turn on this morning. By this afternoon I could turn the spigot but no water. I tried again later afternoon, and thankfully, water is spouting from the fountain. Weather is going to be freezing for tonight and through the morning hours. Do I just leave the pump and fountain on to be safe? I am talking to my pool company tomorrow, I could not reach them today, but thought I'd ask here as well. Sorry if this is too specific or unclear. Thank you.
