How to Use a Drain Cleaning Bladder to Clear a Clog · Step 4 of 6
In this video
A drain bladder, also known as a blow bag, uses water pressure to clear clogs. Attach the bladder to a standard garden hose and insert it into the clogged pipe. When you turn on the water, the bladder inflates to create a tight seal against the pipe walls. Water then shoots out of the tip at high pressure, forcing the clog down the pipe.
Goal: Force the clog out with water pressure
- Ensure the bladder is inserted sufficiently far into the pipe before turning on the water to prevent it from shooting back out.

FAQs
What are the essential safety precautions I need to take before and during this project?
Always wear safety glasses and waterproof work gloves to protect yourself from dirty water and potential splashes. Ensure the work area is well-ventilated and lay down old towels or tarps to contain any spills. Be mindful of the water pressure and avoid standing directly over the cleanout as water can spray out forcefully.
How do I choose the right size drain cleaning bladder for my main drain line?
Drain cleaning bladders are designed for specific pipe diameters, typically ranging from 1.5 inches to 6 inches. You must match the bladder size to the interior diameter of your drain cleanout pipe for it to work effectively and safely. Check the cleanout cover or consult your home's plumbing diagrams if you're unsure of your main line's diameter.
What should I do if the drain bladder doesn't clear the clog on the first try?
If the clog persists, try repositioning the bladder slightly deeper or shallower within the pipe and reactivate the water flow. You can also try increasing the water pressure incrementally, but never exceed the bladder's or your pipe's rated pressure. If after a few attempts it's still not clear, you might need to consider a different method.
Can using a drain cleaning bladder damage my pipes, and how can I avoid it?
While generally safe for most modern pipes, over-inflating the bladder in older, weaker, or corroded pipes can potentially cause damage. Always ensure the bladder is correctly sized for your pipe and avoid exceeding the recommended water pressure. If you feel resistance or hear unusual noises, reduce the pressure immediately.
