SAN DIEGO -- With water becoming a hot commodity, a San Diego man has invented a tool to make sure that not a drop is wasted.

Many people have seen broken sprinkler heads that turn into geysers when a lawn is watered.

Sometimes, many don't realize they have one of these water wasters.

The broken sprinkler heads could be a result of different factors like being run over by a car or snapped during lawn-mowing.

A couple of years ago, Coronado resident Chris Eader said he had enough.

Eader invented "No More Geysers," a sprinkler system that automatically shuts off -- even if someone were to take a golf club to it.

After hitting a No More Geysers sprinkler head, Eader said, "It shuts off completely at the site of the break every time without fail."

Eader said the system is pretty simple. A ball valve goes into a base, with a plastic riser going above it. A retaining pin holds the ball down, keeping the water flowing.

If the sprinkler head were to break the pin gets pushed out and the ball closes the valve.

Eader said his invention could save water and money, as a geyser resulting from a broken sprinkler could waste 10 gallons of water a minute.

"And then you might not notice it for two or three weeks, so you could actually lose thousands of gallons with each break," said Eader.

Eader's invention is turning heads everywhere, from local water districts to Gov. Arnold Schwarzenegger's office.

"Arnold Schwarzenegger this week gave us an audience with one of my sales teams up at his office in Sacramento, and was very impressed with the product," said Eader.

Eader also showed Caltrans his invention, and a representative said it is being reviewed for use alongside local highways.

"We do our own studies on those, do our own small testing on those and see how those can best benefit us as well as our consumers," said Eader.

The Metropolitan Water District, which oversees all of Southern California, has given Eader a grant to study his invention on a larger scale.

If it is successful, users might not have to worry about geysers any more.

One No More Geysers riser sells for $4 and connects to an existing system, while a regular sprinkler head sells for $2.
