We live in Texas and dont close our pools like the people up north. We are getting ready for a light to moderate cold front soon. Temps may get in the high 20's low 30's for a few hours. Normally we wrap our pipes to keep them from freezing. Do we need to wrap the PVC pipes to the pumps when the weather gets cold enough to freeze? I run my pumps during the day and they are off at night. What do people do with their pools during the occasional cold front? It will be warm again next week!
