Residential sprinkler systems use lightweight, inexpensive piping and fittings of plastic, copper or thin-wall steel in place of traditional materials. These sprinkler systems can be built into new housing or added to existing buildings. It is estimated that residential sprinkler systems would add only about one to one and a half percent to the cost of new housing. Because home sprinklers are effective, they may help reduce insurance claims. In many states, insurance companies offer special discounts to homeowners if their home has an approved sprinkler system.
Residential sprinklers are practical.
They are small enough to blend into a typical household and are attractively designed. The sprinkler heads stand out less than one inch from the ceiling. You also can buy ornamental plates to blend in with the decor of a home. A home system uses much less water than an industrial or commercial system. Many people have a concern about sprinklers accidentally going off in their home.
