It is important for homeowners to know where and what certain portions of the sprinkler system they have control over within the unit. In an emergency such as a broken sprinkler head or broken pipe where water is running into the unit, it is perfectly acceptable to locate and shut off the water supply to the sprinkler system. This will alert the fire department and local management company to your home for assistance. They will give further direction at that time, but being able to stop water flowing into your unit inadvertently will help reduce costly repairs.
