The McAlpine TUNKIT-1 is a WC overflow kit designed to provide an effective solution for managing excess water in a toilet system. The kit comprises several components, including the TUN-2 tun dish overflow, a V33T WC connector, a 90° pushfit elbow, and two ¾" x 12" lengths of overflow pipe. The TUN-2 tun dish overflow is designed to fit onto the top of the toilet cistern and manage any excess water that flows out of the overflow pipe. The V33T WC connector is used to connect the tun dish overflow to the flush pipe. The 90° pushfit elbow is used to connect the overflow pipe to the V33T WC connector, while the two ¾" x 12" lengths of overflow pipe provide additional flexibility in installation.
