sprinkler valve

No More Geysers (NMG) is a sprinkler riser with an internal shut-off valve. When a sprinkler head breaks off, NMG automatically shuts off the water at the break. NMG stops the lawn geysers we have all seen; so it conserves water by avoiding water loss when a sprinkler head gets broken off, and it lowers the risk of property damage and liability caused by water flowing out of the sprinkler system.
