Week of April 1, 2007: The 1,750 gallon underground storage tank arrives via FedEx. It will be connected to our roof drains to collect the water that lands on the roof. We will use it for washing our cars and for landscaping needs.

Meanwhile the underslab plumbing continues.

Later in the week, the underslab peagravel, vapor barrier and rigid insulation are installed.

The inslab radiant heating tubes are then laid out and the stub-ups are left in the soon-to-be mechanical room. Unfortunately, even though it's almost the middle of April, we get a light dusting of snow!
