WINTERIZE A BUILDING
Types of leaks in water supply or drain piping: this article describes the different types of plumbing leaks that can occur in building supply piping or drain piping. Knowing just what kind of leak is occurring in a building helps pinpoint the problem and also helps specify the necessary plumbing repair. The articles at this website will answer most questions about freeze protection for piping and other building plumbing and heating system components: how to winterize a building to avoid frozen pipes, and how to thaw frozen water supply & drain piping, wells, & water tanks.

Understanding the types of water leaks that occur in building piping can help you find or watch out for leaks that are not so obvious when water is first turned on in a building. Keep in mind that these are by no means all of the building leaks that can occur. Others include leaky shower pans, leaky air conditioning condensate drains, bad sump pump drains, leaky water tanks, leaky water heaters, leaks at tankless coils, and leaks from outside the building from roof runoff or surface runoff. Here we focus attention on leaks that occur in building piping:
Also see WELL PIPING LEAK DIAGNOSIS. Also if you are de-winterizing or having frozen see Thawing Frozen Pipes which addresses how to find frozen and burst pipe leaks in buildings, and see Repairing Burst Leaky Pipes.

Our main article on this topic is found at WELL PIPING LEAK DIAGNOSIS. Excerpts are below.
At WATER PRESSURE PROBLEM DIAGNOSIS TABLE we note that a possible explanation for loss of building water pressure, or loss of well pump prime can be air leaking into a well piping line, as well as water leaking out of the well pipe.
Water will leak out of a well pipe at a bad connection, perforation, or cracked pipe when the well pump is running, particularly if the water system uses a submersible pump that is located in the well itself. If you have this problem you may find a wet spot in the ground near the well piping, provided that the pipe is close enough to the surface. You will also notice that the well pump is running more often than normal, and that your "apparent" water usage may have increased. Some people even report finding a "water fountain" or geyser in the lawn at a burst water supply pipe from both private wells and from a municipal water main.
Air may leak into a well water pipe at a bad connection, perforation, or other damage when the well pump stops running, particularly if the leak problem is combined with a defective check valve or foot valve in the piping system. The result may be air discharged from plumbing fixtures (see AIR DISCHARGE at FAUCETS, FIXTURES), improper air charge in the water pressure tank, or loss of pump prime. Short cycling of the water pump or loss of pump prime may result as well.
