Workers had to shut off water for some residents as they made repairs to the pipe. Crews found a three- to four-inch hole in the old line.
A homeowner who had water shooting onto her home said she thought it was raining until she looked outside and saw the water flying out of the street.
"It was raining. I thought it was pouring. I went back to bed and the dog kept barking, and this morning I woke up to see Eyewitness News out front," said Jackie Brooks of Fullterton.
"I didn't look out the window. I was just kind of mad because the dog was barking," said Matt Brooks, another Fullteron resident.
Fullerton city officials said the pipes was about 50-years-old, and they were in the process of replacing pipe in the area before the pipe ruptured.
They say the repair was easy and they were able to reopen the street to traffic several hours later.
