I was at the hardware store searching the isles trying to figure out a trough, just for now. I was planning to insulate something better when the ground is thawed. A very nice lady helped me with the de-icer, she said I use this one. so I asked what kind of trough do u have ? She uses an old freezer. Brilliant lol insulated large, has a drain. Is this common ? any one here use a freezer ? or an old fridge would also work ? How do you get the freon gas out ?
