The weather is supposed to remain below freezing while we are away. So, we really need to make sure our pipes won't freeze while we're away.
We emptied and salted our rinse and waste tanks and filled up the fresh water tank. It will be less likely to freeze with more water in it. And, we are making sure the water pump is shut off. We are leaving the furnace thermostat set at 40 degrees. And, leaving an electric heater on low under the cabinet. Also, we are leaving all the cabinet doors open where the water pipes run so the heat can reach them.
And, we are leaving a heat lamp shining on the water pump.
