Rubber Drain Bladder Kit 3 Pack A robust, easy to use solution for clearing stubborn drain clogs in long runs and outdoor lines. Each rubber bladder inflates inside the pipe to form a tight seal and deliver pulsing water pressure that dislodges blockages without chemicals or dismantling plumbing. Key benefits Clears long or deep blockages: Inflating inside the pipe produces pulsing hydraulic pressure that can reach long distances for thorough clearing, reported up to 1,000 feet. Durable, flexible material: Made from rubber for impact and wear resistance, the bladders expand and contract reliably under water pressure for repeated use. Fits a wide range of drains: Three size options cover drain diameters from about 1 to 6 inches, so the kit works on many main drains and outdoor sewer lines. Simple setup and operation: Connect to a cold water tap, insert the bladder into the drain, then open the water supply to let the bladder inflate and clear the clog. No special tools required. Compact kit: Lightweight and portable at approximately 410 g total, easy to store with three different sizes included. What is included 3 x Drain Bladder Sizes and weight Total weight: approx. 410.00 g / 14.46 oz Size A: approx. 12.95 x 2.54 cm / 5.1 x 1 in Size B: approx. 3.8 x 16.5 cm / 1.5 x 6.5 in Size C: approx. 6.35 x 18.54 cm / 2.5 x 7.3 in Performance and compatibility Suitable for drains with diameters from about 1 inch to 6 inches. Operates effectively using cold tap water only; do not use hot water. Recommended inflation pressure range: 40 to 80 psi for effective sealing and pulsing action. For results insert the bladder at least 6 inches into the drain before inflating. How it works Attach the bladder to a cold water tap. Insert the bladder into the drain and open the water to inflate. The bladder expands to form a seal, then hydraulic pulses created by the water flow dislodge and push blockages downstream. Typical applications Outdoor sewer and yard drains where roots, silt, or debris cause slow flow. Main line cleanouts and long downhill drain runs that are difficult to reach with a hand auger. Seasonal gutter and storm drain maintenance to remove accumulated debris and restore flow. Usage notes Use only with cold water. Insert at least 6 inches into the drain before inflating. Maintain inflation pressure between 40 and 80 psi. Inspect bladders for damage before each use and if worn or compromised. This kit provides a practical, reusable method for maintaining a variety of drain types without disassembly or chemical cleaners.
