How to Use a Drain Cleaning Bladder (Blow Bag) to Clear a Clog · Step 1 of 6
In this video
Before starting any work, prepare the area under the sink. Begin by shutting off the hot and cold water supply valves, typically by turning them clockwise. Place a bucket or container underneath the plumbing to catch any water that will drain from the lines. Open the existing faucet to release any pressure and drain the remaining water. Finally, use an adjustable wrench to disconnect the hot and cold water supply lines from the shutoff valves.
Goal: Shut off water and disconnect supply lines
- If you cannot find or operate the shutoff valves under the sink, you will need to shut off the main water valve for the entire house.
- Keep a towel handy to clean up any spills immediately.

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.
