The most common sign that a water fountain is in need of repair is a water leak. A water leak tends to be a relatively minor problem that can easily be handled. Another sign is the temperature of the water; overly warm water can be a sign that the temperature regulator has blown.

There will eventually come a time when a water fountain needs to be replaced rather than spending money on repairs. However, you can save yourself quite a bit in expenses if you learn how to properly identify when it should be replaced.
