America's foremost paranormal plumbers will have more chances to check out a haunting near you.

Sci Fi Channel has ordered 13 new episodes of "Ghost Hunters" and seven more episodes of "Destination Truth," extending their current seasons.

"Ghost Hunters," in its fourth season, follows Roto Rooter employees/investigators Jason Hawes and Grant Wilson moonlighting as ghostbusters. With their TAPS (The Atlantic Paranormal Society) team, they seek out reported hauntings and use equipment to test moving furniture, bumps in the night, mysterious voices and eerie visages to determine their ghostly authenticity.

On April 9, the episode in which a U.S. Air Force base was investigated attracted 1.8 million adults 24-54, the best ever for a Sci Fi original reality series telecast.

The show will follow up on its success with its third annual "Ghost Hunters Live" special on Halloweeen night. The show also recently launched a successful spinoff, "Ghost Hunters International."

"Destination Truth" is in its sophomore season and centers on the exotic travels of Josh Gates, who seeks to find answers to some of the world's most notorious unexplained mysteries.
