Working principle: Unclog sink drain bladder is designed to expand inside a pipe, seal the pipe, and provide just enough flow to pressurize the pipe behind the clog. Great for unclogging stubborn blockages in outside main drains/sewer lines/bathroom/bathtub/shower/kitchen/basement/swimming pool.
Reliable material:Drain unclogger kit is made of high quality rubber with good ductility, which can expand and contract freely when pressurized with water. It can be used for a long time in a variety of environments and is not easily damaged. The metal inlet is compatible with most garden hoses or water pipes.
Save time&money: No need to call plumber or use traditional clog remover tools, just need the drain cleaning bladder and a garden hose. Greatly saves a lot of work time and sewer repair costs.
Great alternative to chemical products or drain augers that might leave residue in your plumbing system.
Important Tips: When using, connect the drainage cleaning bag to the cold water faucet and insert it into the drainage pipe for at least 6 inches for optimal results; The minimum pressure for inflation is 40 psi, and the maximum pressure is 80 psi
