I have a cabin on the Little Manistee. This will be the first full winter we have owned it. The cabin is built on a concrete slab; the well pit (pump, hot water heater, etc) is about 6 feet below grade under the slab and the exterior metal access cover on the adjacent covered porch, above. In other words, the cover of the pit is about 1/2 concrete slab and the other half a metal access plate exposed to the outside that lifts up to gain access. The floor of the pit is mostly dirt. The cabin can be heated 24/7 with thermostatically controlled propane heating system that I recently installed; however, there is no way to divert any of that heat into the pit. Historically, prior owners have simply drained the system and put antifreeze in the toilet and sinks to prevent freezing. What this meant was that everytime you went up there, you had to crawl down in the pit, prime the pump, etc to get running water. Interestingly, jugs of primer water kept on the dirt floor never froze. I think I can keep the pipes in the cabin (sink, toilet, shower, etc) from freezing with the central heat. I'd like to keep the water system primed so that I don't have to climb down in the pit in the dark when we go up there in the winter. No one ever had to address this before because there was no central heating system for the cabin. What would you suggest for the pit? Heat tape...styrofoam cover over the pit area...or just keep biting the bullet and climb down into that thing in the dark on Friday nights to re-prime the pump? I'm open to all suggestions.
