In the construction business, you probably rely on your industrial air compressor quite a bit. If you don't take good care of your air compressor, however, you won't be able to rely on it for very long. One of the main things that you will need to do to take good care of your air compressor is to empty out the water tank each and every day. This might seem like an unnecessary annoyance, and it might not seem like a serious problem if you forget to do it every now and then.
