While there is growing recognition of the enhanced ability of residential sprinkler systems to protect life and property from fires, very few existing one- and two-family homes in the U.S. include a sprinkler system. One study based on 15 years of data from Scottsdale, Arizona categorized fire damage in two types of homes—those with fire sprinkler systems and those without fire sprinkler systems. The study reported property loss due to a fire in a residential home with a sprinkler system was $ 2 166 compared to $ 45 019 in the homes without a sprinkler system. What is the overall cost of residential sprinkler systems? A recent NIST report addresses the life-cycle cost of these systems. The report, “Economic Analysis of Residential Fire Sprinkler Systems” by Hayden Brown, NISTIR 7277, designs and applies a comparative life-cycle cost analysis to multipurpose network and stand-alone fire sprinkler systems designed in compliance with NFPA 13D. (This report is the first of two reports estimating the cost and benefits of fire sprinkler systems in residential single family housing.) The cost of each sprinkler alternative is estimated for a set of three

The Hunter PGP is by far my most favorite adjustable rotary sprinkler head for residential sprinkler systems. This gear driven sprinkler runs very quietly and smoothly. It comes with either 12 standard or 7 low angle nozzles to get different spray patterns, and is very easy to adjust the radius, from about 5 degrees to a full 360 degrees. Each head comes with a small key that makes it very easy to adjust the degree of rotation
and to adjust the distance to some degree, depending on the nozel you are using. When setting head and making adjustments, you can just rotate it by hand forward to the next stop and then back to the previous stop to make quicker adjustments. Many heads do not have this feature, and although you do not need to adjust them very often, it sure is more convenient then waiting for it to rotate back and forth on it’s own and getting things wet that you don’t want to (like your kids or something) in the process. It has a very nice seal with a rubber top so dirt always gets pushed out when the head comes down. The oldest system I have installed is almost 8 years ago and I used the Hunter PGP’s.
