The device comprises a hose member able to withstand without rupture minimum water pressures of 175 psi or greater, two bushings for sealing the open ends of the hose member, a hose bib communicating with the interior of the hose member, a plurality of clamps to securely connect the hose member to the upper and lower bushings so as to provide watertight connections, and an extension piece extending from the interior of the hose member below the hose bib for use in remote removal of a sprinkler head positioned within the interior of the hose member. Applications may include, but are not limited to, use in removing sprinkler heads from overhead sprinkler systems in commercial buildings during routine maintenance, renovation, and repair work.
