Open Cabinet Doors Under Sinks on Exterior Walls

What happens here

For sinks that are situated against exterior walls, open the cabinet doors directly underneath them. This action allows the warmer ambient air from inside the house to penetrate the cabinet space and circulate around the exposed water supply lines. The increased temperature within the cabinet helps to prevent the pipes from reaching freezing temperatures, thus significantly reducing the risk of a burst pipe. Ensure any items stored in the cabinet are moved to avoid obstructing airflow, allowing for maximum heat transfer.

Goal: Open the cabinet doors beneath any sink located on an exterior wall to allow warmer indoor air to circulate around the exposed plumbing.
