Frequently asked questions

Drain Opener is a compressed gas product. When the formula in the can is released and comes in contact with water in your drain, it expands rapidly, creating a standing wave. This uses the water in the pipe like a battering ram to help push the blockage through while cleaning the walls of the pipe.

Each 4.5 oz can of Drain Opener contains up to 15 applications. For best results, press the can for only one second at a time. Holding the can down longer may reduce the number of applications available.

Drain Opener can help clear common clogs caused by hair, grease, food particles, and soap buildup. It is designed for blocked and slow-moving drains in sinks and tubs.

Drain Opener can work on clogs up to 50 feet away, depending on the diameter of the pipe. It may reach up to 50 feet down a 1.5-inch pipe, 40 feet down a 2-inch pipe, 35 feet down a 3.5-inch pipe, 25 feet down a 4-inch pipe, and 18 feet down a 5-inch pipe.

Drain Opener will not harm sound plastic or metal plumbing when used as directed. Do not use it on damaged, weak, or unsound plumbing. If you are unsure about the condition of your plumbing system, consult a qualified plumber before use. Always follow package directions and safety precautions.

Yes! Drain Opener works great on this annoying problem. Simply follow the directions for a blocked drain (as stated on the box or can) ensuring that you fully submerge the green cap in water. Then give Drain Opener a slightly longer application. Your drain will run freely once again.

Treating slow drains early may help restore normal flow before a complete blockage develops.
