(knocks on wood)
Haven't had frozen septic here. Maybe we use more water in Michigan.
What if you took 2 hot showers per day? Dumped some heat into the system?
Ground here only freezes to about 6 inches. Maybe a bit more for real cold winters. Although, seems like some cities had a problem with water pipes last year or so. The -20 temps really did them in. People were running water (trickle) out hoses to keep the water flowing and thawing pipes. I think Fran's correct about snow cover too.
Good morning snails.
