Some believe the drought is a little overstated. Regardless I don't think that water conservation should be taken lightly or ignored....
California's claims of three-year drought are all wet
The No More Geysers Riser a highly effective water saving device that
retrofits into an existing sprinkler system. When a sprinkler head is
broken the riser will shut off the flow of water at the break
maintaining the integrity of the system stopping the typical geysers
and saving thousands of gallons of water. Got Geysers? don't want them
