A removable casing for a fire sprinkler head encases the sprinkler head to stop unwanted water spray. The casing has hinged shells that latch closed to form a watertight interior space. One or both of the shells have gaskets that contact the opposite shell to seal off the interior space. The hinges and latches may be adjustable to make the casing easier to fit over the sprinkler head and to fasten tightly. Each shell may have one or more necks configured to fit tightly around a pipe when the casing is closed. A drain having a valve may be disposed through one or both of the shells to prevent initial pressure buildup and to allow the removal of accumulated water from inside the casing. The casing fills with water until the flow out of the sprinkler head stops, allowing the rest of the fire sprinkler system to remain active. |
