If you have a badly blocked drain that cannot be cleared using simple methods, such as a plunger or a liquid drain cleaner, you may need to try more advanced techniques. Here are some steps you can follow to unblock a badly blocked drain:
Remove any visible debris: Before attempting more advanced techniques, try to remove any visible debris from the drain, such as hair, food scraps, or soap scum. Use a pair of pliers or a drain grabber to carefully pull out as much of the debris as possible.
Use a plumbing snake: A plumbing snake, also known as a auger, is a long, flexible rod with a spiral or corkscrew tip that is used to clear blockages in drains. To use a plumbing snake, insert the snake into the drain and push it through the blockage, using the spiral tip to break up or remove the debris. If the blockage is too far down the drain to reach with the snake, try turning the snake handle in a clockwise direction to loosen the blockage and make it easier to remove.
Use a hydro jet: Hydro jetting is a powerful method of clearing blockages in drains using high-pressure water. To use a hydro jet, you will need to rent or purchase a hydro jet machine, which is a specialized piece of equipment that uses a high-pressure hose and nozzle to blast water through the drain. Be sure to follow the manufacturer’s instructions and safety guidelines when using the hydro jet.
Call a plumber: If you are unable to unblock the drain using these methods, or if the blockage is causing slow or backed-up drains, it may be time to call a plumber. A professional plumber will have the tools and expertise to clear even the most stubborn blockages, and can also help to identify and fix any underlying issues with the plumbing system.
It is important to note that unblocking a badly blocked drain can be a challenging and potentially hazardous task, and it is always a good idea to use caution and follow proper safety guidelines when attempting to clear a blockage. If you are unsure of how to proceed, or if you are concerned about the condition of your plumbing system, it is always a good idea to call a professional plumber for assistance.
