After 1-2 minutes of operation, have your helper turn the water spigot completely off. Wait a moment for the water pressure in the hose to dissipate and for the bladder to deflate. You will feel the hose go limp. Once deflated, carefully pull the hose and bladder out of the drain. Remove the wet rag you placed in the overflow. To test your work, turn on the bathtub faucet and observe how the water drains. If it flows away quickly and without backing up, the clog has been successfully cleared. If the drain is still slow, you can repeat the process one more time. If a second attempt fails, the clog may be too solid or too far down the line for this method. Use your remaining rags to clean up any water that spilled during the process.
Step 1
⏱ 2 min
Prepare the Work Area and Gather Tools
Begin by ensuring your safety and preparing the work area. Put on your safety glasses to protect your eyes from any potential splash-back and wear waterproof gloves. Gather all necessary items: the correctly sized drain cleaning bladder, a garden hose long enough to reach from a spigot to the clogged drain, and several old rags or towels. Clear the area immediately around the drain, removing any bottles, mats, or personal items from the bathtub or shower to prevent them from getting wet or in the way.
Step 2
⏱ 2 min
Choose the Correct Drain Bladder Size
Examine the packaging of your drain cleaning bladder to confirm it is designed for the diameter of your drain pipe. Bladders are not one-size-fits-all; they are rated for specific pipe size ranges, such as 1.5 to 2-inch pipes or 3 to 4-inch pipes. Based on our assumption of a 2-inch bathtub drain, you will need a bladder rated for that size. Using a bladder that is too small for the pipe will fail to create a proper seal, rendering it ineffective. Using one that is too large may not fit into the drain opening or could potentially damage the pipe when it inflates.
Step 3
⏱ 2 min
Attach Bladder to Garden Hose
Take the male, threaded end of your garden hose and firmly attach it to the female, threaded fitting on the drain cleaning bladder. Hand-tighten the connection to ensure it is secure and will not leak under pressure. Do not use tools like pliers, as this can damage the plastic or brass fittings on the hose or bladder. A snug, hand-tight connection is sufficient.
Step 4
⏱ 2 min
Access the Drain and Block the Overflow
To gain access to the pipe, you must first remove the drain strainer or stopper from the bathtub drain opening. This may require a screwdriver for some models, while others can be lifted or twisted out by hand. Next, locate the overflow plate, which is the metal plate with slots or holes located on the wall of the tub below the faucet. This overflow connects to the same drain pipe. To prevent water from backing up and shooting out of this opening, you must block it. Take one of your old rags, get it thoroughly wet, and wring it out slightly. Tightly pack the wet rag into the overflow opening, ensuring a complete seal. This step is critical for directing all the water pressure from the bladder towards the clog.
Step 5
⏱ 2 min
Insert the Bladder into the Drain Pipe
With the drain open and the overflow blocked, carefully feed the bladder end of the hose into the drain pipe. Push the hose in, guiding the bladder past any initial bends. Continue feeding it until the bladder itself is at least 6 to 12 inches deep inside the pipe. This positioning is vital. It ensures the bladder is securely anchored within a straight section of the pipe, which will prevent the force of the water from ejecting it back out of the drain. The hose should be relatively straight behind the bladder, without any kinks.
Step 6
⏱ 2 minApply Water Pressure
Hold the garden hose firmly a foot or two back from the drain opening. Signal your helper to turn on the water spigot fully and quickly. If working alone, turn the water on and quickly return to the drain. You will feel the hose stiffen and pulse as the bladder inflates to seal the pipe. Once sealed, the bladder will release powerful jets of water against the clog. The hose may jerk or vibrate as it works. Allow the water to run for 1-2 minutes to give it time to break down and flush the clog. Be vigilant for any signs of water backing up in other drains or leaks in your plumbing system, and be prepared to shut the water off immediately if this occurs.
