A skimmer protector with integral blow tube is a hollow, substantially closed, blow-molded body of resilient resin material having a cylindrical projection on one end with external screw threads for threading into the intake pipe of a swimming pool skimmer with an open integral tube running from and through said screw threaded portion to an opening elsewhere on its blow-molded body. The cylindrical projection on the body of the device is intended and designed to be threaded into the intake pipe or other part of a pool skimmer. When connected thereto, the skimmer protector is positioned to absorb/buffer the forces exerted by the expansion of ice as it freezes within the walled regions of the skimmer. The aforesaid integral tube serves to create a sealed air space between the tube and the outer walls. This sealed air space helps to resiliently stiffen the body of the skimmer protector, allowing it to better perform its function in absorbing ice expansion pressure. In addition, this sealed integral tube can be used as a blow-out tube to assist in the removal of water from the piping connected to the skimmer.
