The “recessed installation tool” is for remote installation of a fire sprinkler head adaptor, or other device while it is positioned in a recessed or obstructed area that does not allow standard installation methods. This invention is a device for installing sprinkler heads from the type of overhead sprinkler systems commonly found in residential or commercial buildings. The device (or tool) would accommodate the “CPVC CUT BACK KIT” and the specific use of this tool is for obstructed or recessed fire sprinkler heads or adapters with minimum access holes or cuts. It being unique as it is a “code compliant” way to cut back a fire sprinkler head in or above hard ceilings such as drywall, stucco, or plaster without opening up the ceiling to perform the task. This tool is the only code compliant way to reinstall the “head adapter” without damaging the sprinkler head with the CPVC® cement, glue or bonding agent. This installation tool keeps the waterway open as the cement, glue or bonding agent dries. This tool also installs the slip by thread adapter for hose bibs or other fittings of standard ½″, ¾″ or 1″ size that need to be adjusted that are concealed above or behind block, stucco or drywall. The Head adapter is the CPVC or PVC fitting that adapts from the slip and glue method of CPVC and PVC pipe to the threads on a sprinkler head or other fitting and because it has a penetrating rod that protrudes into the fitting as it is being glued it will keep the waterway open as the cement dries which will never obstruct the waterway/water flow. This tool may include, but not limited to, use in installation of fire sprinkler heads from overhead sprinkler systems in commercial and all types of buildings during routine installation, renovation, and repair work.
