How to Use a Drain Cleaning Bladder (Blow Bag) to Clear a Clog · Step 1 of 6
In this video
Wearing protective gloves, slowly loosen the slip nuts on both ends of the P-trap by turning them counter-clockwise. These can typically be loosened by hand. As the seals break, water will begin to drain into the bucket. Carefully lower and remove the P-trap section. A large volume of water will likely gush out. Once drained, inspect the removed pipe for the clog and clear it out. The clog is often a buildup of grease and food particles.
Goal: Disassemble the P-trap to access and remove the clog
- The water draining from the sink will be dirty and may gush out quickly. Loosen the final connection slowly to control the flow.

FAQs
Can I use a drain cleaning bladder on all types of plumbing pipes?
No, drain bladders are generally safe for most sturdy household pipes but should be avoided with old, brittle, or cracked pipes, which could burst under pressure. Do not use if chemical drain cleaners have recently been used, as mixing chemicals and pressurized water can be dangerous.
How do I determine the correct size drain cleaning bladder for my specific pipe?
Drain cleaning bladders are designed for specific pipe diameters (e.g., 1.5-inch, 3-inch). You'll need to know the approximate diameter of the drain pipe you're clearing. Check the bladder's packaging to ensure it matches your pipe size for optimal sealing and effectiveness.
What water pressure should I use, and how can I prevent pipe damage?
Start with low water pressure and gradually increase it, listening for any unusual sounds. The bladder works by sealing and then forcing water through; excessive pressure can damage older or weaker pipes. Never exceed your home's standard water pressure, and release pressure if water backs up too quickly.
The bladder isn't clearing the clog; what are my next steps?
If the clog persists after several attempts, the obstruction might be too severe or a type the bladder can't clear, like a solid object or root intrusion. You may need to try an alternative method, such as a drain snake, or consider calling a professional plumber.
