Take the metal, threaded end of the drain cleaning bladder and attach it to the male end of your garden hose. Screw it on by hand, ensuring it is snug and secure. The connection should be tight enough to prevent water from leaking at the joint when under pressure. Do not overtighten with a wrench or pliers, as this can crack the plastic or brass fitting on the bladder.

Preparation and Safety
Begin by prioritizing safety. Put on your safety glasses to protect your eyes from potential backsplash of dirty water and a pair of waterproof gloves to keep your hands clean and dry. Locate the main line cleanout access port. Because backflow or spills are possible, place a shallow bucket or lay down several old towels around the cleanout opening to protect the floor. Gather all your necessary tools, including the correctly sized drain cleaning bladder, a durable garden hose, and a pipe wrench if the cleanout cap is too tight to open by hand.

Select and Inspect the Bladder
Examine the packaging of your drain cleaning bladder to confirm it is rated for the diameter of your pipe, which we've identified as 3-4 inches. Using the wrong size is ineffective and risky. A bladder that is too small will not create a proper seal, while one that's too large may not fit or could become lodged. Once you've confirmed the size, perform a thorough visual inspection of the bladder itself. Look for any cuts, punctures, cracks, or signs of dry rot in the rubber. A compromised bladder can burst under pressure inside your pipe, turning a clog into a much more difficult retrieval and repair job.

Insert Bladder into Drain Pipe
With the cleanout cap removed, begin feeding the bladder and the attached garden hose into the drain pipe. Push the hose deliberately, guiding the bladder into the pipe. Continue feeding it until the bladder is well inside the pipe, at least 6-10 feet if possible. The goal is to get the bladder past any immediate bends or wyes near the opening and closer to the actual clog. The bladder must be fully contained within the pipe for it to inflate and seal correctly.
Step 5
⏱ 2 min
Activate the Bladder
This is the most critical step. Firmly grip the garden hose with both hands, bracing yourself for significant back pressure. Signal to your helper to turn on the water at the spigot. It's best to turn it on fully and quickly. The bladder will immediately begin to inflate, pressing against the inner walls of the pipe to form a seal. Once sealed, a concentrated, high-pressure jet of water will blast from the tip of the bladder directly at the clog. The hose will pulse and push back against you. Apply water in short, powerful bursts of 20-30 seconds, then have your helper turn the water off. Repeat this pulsing action several times. Listen carefully for a 'whoosh' sound and feel for a sudden decrease in back pressure, which indicates the clog has been dislodged.
Step 6
⏱ 2 min
Verify and Retrieve
After you believe the clog has been cleared, have your helper turn the water supply off completely. Wait for at least 30-60 seconds. This allows the water pressure to dissipate and the bladder to fully deflate. Do not attempt to pull it out while it is still inflated. Once deflated, the bladder and hose should slide out of the pipe with minimal resistance. Before replacing the cleanout cap, test the drain line. Go to a fixture inside the house (e.g., flush a toilet or run a sink) and let a significant amount of water flow into the drain system. Watch the open cleanout to ensure water is flowing past it freely and not backing up. If it flows well, you can securely replace the cleanout cap, using a pipe wrench if needed to snug it up.
