How to Use a Drain Cleaning Bladder (Blow Bag) to Clear a Clog · Step 1 of 6
In this video
Begin by gathering all the necessary tools and supplies. This includes a hammer, pliers, screwdrivers, a sprinkler valve key, a borescope camera, and a metal wire or bucket handle for making a hook. Also, have a bottle of Calcium, Lime & Rust (CLR) remover ready. Lay a towel in the bathtub to protect its surface. Before starting, use pliers to slightly bend the forked tip of the sprinkler valve key inwards so it can grip the crossbar of the drain stopper.

- Sprinkler Valve Key (Tool Type: Hand Tools) — Providing the length and leverage needed to twist and break the corroded stopper free.
- Borescope Camera (brand: Klein Tools, Tool Type: Plumbing Tools) — Visually inspecting the stopper inside the dark overflow pipe and guiding the placement of other tools.
- Pliers (Tool Type: Hand Tools) — Bending the tip of the sprinkler valve key to modify it for gripping the stopper.
- Bucket Handle — Fashioning a hook to retrieve the stopper once it is broken loose.
- Hammer · optional — Shown as a potential tool, though twisting was found to be a superior method for this task.
- Screwdriver · optional — General purpose plumbing repairs, though not explicitly used for the main task in the video.

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.
