ALMOST every building and home in the suburbs and big cities have automatic lawn sprinkler systems. These systems are "nig-rigged" at very best, and also expensive to and complicated to fix. This gives the prankster good fertile ground for using these systems for evil. Imagine some grounds keeper runnin around digging up the yard looking for non-existant leaks(or real ones)
1_valv boxes_LOOK FOR LITTLE GREEN PLASTIC COVERS ON THE GROUND, SOMETIMES ROUND SOMETIMES RECTANGULAR. OPEN IT UP.INSIDE WE HAVE 1-4 VALVES HALF BURIED IN DIRT, LOCATE THE SMALL BLEEDER KNOB OR PHILLIPS SCREW AND LOOSTEN IT SLIGHTLY, YOU NOTICE THAT SOME SPRINKLERS COME ON, NOW UNSCREW IT ALL THE WAY AND TAKE IT WITH YOU, NOW THEY CANT SHUT THE SPRINKLERS OFF. aLSO YOU CAN UNSCREW THE SOLONOID WHICH IS THE BLACK CYLINDER THE SIZE OF A FILM CANISTER.
2_sP get a big channel lock pliers (or u can use your hands if your strong) and unscrew all the sprinkler heads(in the ground) it will make a big swamp out of theyre yard, or just unscrew one and it will shoot off when the system is turned on.
There is a lot more you can do with this, but tthose are the easy ones.
3_PIPES_ is underground pipe made out of polypropolene pipe buried 6-8" underground, usually directly along the curb or sidewalk line( you can find it by lining up with a valve box as the pipe is in line with the valves) Get one of those sticks-with-the on it for picking up trash, and "AIREATE" your targets lawn right above the sprinkler line, water wont spray out unless you hit the mainline, which will be between the house and the first valve box, if you hit the main line, thats a bonus.
NOTE remember that if you do it to a house, as soon as you turn on some sprinklers they might hear theyre water running.
