Abstract

An anti-drain clogging device used to containerize and dispense anti-clogging solution into a drain pipe in a controlled slow flow manner over an extended period of time. The anti-drain clogging device has a main container section for holding anti-drain clogging solution and a dispensing section for directing the anti-drain clogging solution from the container section to the inlet of a drain pipe. The device has both a liquid-tight, stable storage mode that the device is placed in prior to use and an operational mode where the device is adjustably fixed over a drain pipe inlet. In the operational mode, the dispensing section is adjusted to a chosen position over the opening of the drain pipe inlet by adjusting a support collar attached to the device. In this position, anti-clogging drain solution drips from the dispensing section in a controlled, slow manner into the drain pipe to steadily dissolve, layer by layer, the clogging and sediment in the pipe over a period of time.
