Clogged toilets and drains can be frustrating, but they are certainly an avoidable problem. This Dial plunger set features unique air pressure technology. It shifts any blockages from the narrow areas of the pipe to the larger ones. Conventional plungers pull the blockages into narrow pipes and can cause damage to your plumbing. The larger plunger attachment is suitable for use on clogged toilets and the smaller one is perfect for use on kitchen or bathroom sinks. This is a chemical-free way to free up blockages.
