While some plumbing issues can wait or even be fixed on your own, there are a few times that call for an emergency plumber. For example, if a pipe bursts in your home, this can cause large water damage. This is something you should get taken care of right away. Similarly, an overflowing toilet, a large leak, or a sewer backup should be taken care of as soon as possible. While it may not seem dire, any water heater issues should be taken care of right away, as it could be a sign of a larger water issue.
