Tom, I feel for ya, Im in the same boat you are, my house also is on a slab but the guy who built it put the waterlines in the attic. It's O.K. untill you get a leak but they saty warm from the rising heat of My Woodstove. My problem is the well to the house as my pump is in my barn, wich used to be the house that's why the water goes there first. I have to keep the barn warm to keep the darn pump warm so it does'nt freeze. Tonight here in Western New York, Lake Effect Snow Belt Capitol of N.Y.as were 5 miles off Lake Erie it's Zero tonight but 20 Below with the wind chill. As for shooting My ML's, I went out today, quick to look for Coyote and they wer'nt even out! We shoot all Winter here for them SOB's it's fun and good practice for deer.
