OUR OFF THE GRID WATER SYSTEM IN WINTER
We have an amazing lake pump system that is both ingenious as well as simple. I say ingenious only because it was the previous owner that installed the system. I'm just the caretaker.
HOW OUR OFF THE GRID WATER SYSTEM WORKS IN WINTER
Our house elevated on bedrock showing the path of glycol and water from water tank room to the lake pump
The lake provides all our water needs. This includes our drinking water, which we filter. Read our Big Berkey water filter review for the lowdown.
The lines from the glycol tank run in a simple closed “loop” system. There's an enclosed rubber hose (about 500 feet worth) running along each side of the waterline. Hot glycol circulates inside the hose, alongside the water line to keep it from freezing.
STEP #1: HEAT THE GLYCOL
To start the process we have to first turn the glycol heater from “Vacation” mode to “Hot”. We then allow that to heat up for 30 to 45 minutes, depending on the temperature.
STEP #2: TURN ON THE ELECTRIC GLYCOL PUMP
After the glycol gets to a nice temperature, I turn on the electric glycol pump (see below). This actually “pulls” the glycol from the 5-gallon holding tank above it. It then forces the glycol into the loop down to the lake and back.
STEP #3: TURN ON THE LAKE PUMP
This is the pump that sends the (really cold) lake water up to the house. To do this we head to the breaker panel in the house and hit the double breaker that activates our Franklin Electric ½ hp submersible lake pump.
