How to Use a Drain Cleaning Bladder (Blow Bag) to Clear a Clog · Step 3 of 6
In this video
The user takes the drain bladder and inserts it deep into the floor drain opening. Once it's in place, they turn the shut-off valve on the hose. This allows water to flow, causing the rubber bladder to expand and form a tight seal against the inside of the pipe. The water then jets out from the tip of the bladder, directing high pressure towards the clog.
Goal: Apply water pressure to the clog

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.
