A long time ago when your basement was built it was common practice to install a floor drain. This drain was installed in case something awful happened in the basement, the drain would allow water in the basement to leave. Things like a broken pipe or a washing machine leak would cause a minor flood in the basement and the floor drain would solve any problem.
That sounds like a great idea except that pipes seldom if never broke and the washing machines are far more dependable today. In other words the floor drain just waits for a problem that probably is never going to happen.
Where does the floor drain go to? The other end of that pipe usually goes out into the lawn or someplace where the end of the pipe is exposed to the outside air, this is typically called going to “daylight.” What is never mentioned is that the daylight portion of the pipe is the cold air of winter. And, the floor drain rapidly becomes a huge source of Cold Air Penetration. Cold air rushes in through the pipe into the basement.
Solution – (this one is really easy) cover the drain with some sort of stopper so that the drain is effectively closed.
Once you have closed off the floor drain you have eliminated another source of cold air coming into your home; you have greatly affected the energy consumption within your home.
