Efficient Drain Cleaning Kit: This set includes three drain rubber bladders in different sizes, compatible with drain openings ranging from 1 to 6 inches in diameter. Using water pressure, the bladder expands to seal the pipe and deliver pulsating force that effectively clears clogs in drains and sewer lines. The system can reach distances up to 1000 feet, making it ideal for cleaning various main drains and exterior sewer lines. Easy to Use: The drain bladder utilizes water pressure to clear slow or blocked drains in main lines and sewers. It is simple to operate and suitable for regular maintenance. There is no need for professional plumbing services or chemical drain cleaners. Quality Material: Made from durable rubber, the bladder is designed for long-term use in demanding environments. It offers excellent wear resistance, remains intact under frequent use, and resists damage. The highly elastic rubber allows the bladder to expand and contract reliably when pressurized, providing strong impact resistance. Wide Range of Uses: This kit helps remove blockages caused by hair, soap residue, grease, and other common debris without using harsh chemicals. It is suitable for various types of drains, including sinks, bathtubs, and showers. Important Tips: Connect the drain cleaning bladder to a cold water faucet—do not use with hot water. For optimal performance, insert the bladder at least 6 inches into the drain pipe. The recommended operating pressure ranges from a minimum of 40 psi to a maximum of 80 psi.
