How to Use a Drain Cleaning Bladder (Blow Bag) to Clear a Clog · Step 1 of 6
In this video
Gather the necessary tools for the job. You will need a wet/dry shop vacuum, screwdrivers to fit your drain cover (typically Phillips or flathead), a flashlight for better visibility into the drain, and protective gloves. It is also a good idea to place a protective mat on the shower floor. Before you begin, ensure the filter is removed from the wet/dry vac so it can safely collect water.
Goal: Prepare for drain unclogging
- Always remove the paper filter from a wet/dry vac before using it to suction liquids to avoid ruining the filter and damaging the vacuum motor.

FAQs
How do I choose the correct size drain cleaning bladder for my pipe?
Selecting the right size is crucial for effectiveness and safety. Your drain bladder should match the interior diameter of the pipe you're clearing; for example, a 3-inch bladder for a 3-inch pipe. Using a bladder that is too small will not create enough pressure to dislodge the clog, while one that is too large might get stuck or not fit at all. Always measure your cleanout access pipe or consult your home's plumbing diagrams if unsure.
What essential safety precautions should I take when using a drain cleaning bladder?
Always wear safety glasses (like MCR Safety BearKat Safety Glasses) and sturdy gloves to protect against splashing water and potential debris. Ensure you have a clear understanding of where the water pressure will be directed and place towels around the cleanout to manage any overflow. Never exceed the recommended water pressure or use the bladder in a drain where chemical drain cleaners have recently been used, as this can create dangerous fumes.
What should I do if the drain cleaning bladder doesn't clear the clog?
If the initial attempt doesn't clear the clog, try repositioning the bladder slightly deeper into the pipe and apply water for a longer duration (up to a few minutes). If the clog persists, it might be too dense, too far down the line, or a different type of obstruction (like tree roots) that requires a different approach. At this point, consider using a drain auger or calling a professional plumber.
Can using a drain cleaning bladder damage my plumbing system?
Yes, improper use can potentially damage older, corroded, or PVC pipes, especially if the pipe joints are weak. To prevent damage, ensure you use the correct size bladder and apply water pressure in controlled bursts, rather than a continuous, high-pressure stream. If you suspect your pipes are old or fragile, it's best to consult a professional before attempting this method.
