CLR Power Plumber® Pressurized Air Drain Opener - 4.5 oz.

Restore your system to its original functionality with this CLR Power Plumber Pressurized Drain Opener. CLR Power Plumber works on a different premise than any of the leading drain openers. Power Plumber relies on compressed gas to clear drains. When the formula in the can is released and comes in contact with water in a drain, it expands rapidly creating a standing wave. Power Plumber uses the water in pipes as a battering ram pushing the blockage through and clearing the walls of pipes.
