  • VERSATILE PLUMBING DEVICE
    Publication number: 20100058519
    Abstract: A versatile plumbing tool for obviating household drain blockages is primarily operated by a manually operated air pump; however its utility is greatly increased by making it adaptable for operation by household water pressure. The annular housing of an anti-back flow valve functions as a hand grip for applying sealing down pressure on the discharge head during a drain unlocking operation.
