Sinks, baths, toilets, and external downpipes. Professional high-pressure and rod equipment. Diagnosis before action. For superficial blockages in sinks or basins, a cheap manual drain rod from a hardware store and half an hour of patience are often enough. If the water starts to move, keep going. If after 30-45 minutes it's still blocked, call us. Insisting only makes the situation worse because you push the blockage further into the pipe. The plumber's first step is to find out where the blockage is. There's no point inserting a rod blindly if the blockage is two floors down. For this, we use an inspection camera, a thin camera on a flexible cable that travels through the pipe and shows the exact location and nature of the blockage on screen. Hair, grease, plant roots, foreign objects, fragments from old building work.

For downpipes and multiple blockages (more than one bathroom affected, water backing up in one when you use another), always call a plumber. This is a common installation issue requiring professional tools and often coordination with neighbours. The most complex case is a blockage in a downpipe. The downpipe is the vertical pipe that collects wastewater from several floors in a building. When it gets blocked, it usually affects multiple residents at once. This is where high-pressure machinery comes in, capable of jetting water at 150 bar to clear everything. It's the most effective equipment but also the most delicate. If the pipe has cracks or weak joints, the pressure could worsen things. For toilets that get blocked, a standard plunger only works if the blockage is superficial. When the blockage is deeper, in the toilet's internal trap or the first bend of the downpipe, you'll need a professional drain rod or a small rotary machine. It's important to know this because many people end up removing the entire toilet, thinking it's the only way. In reality, it's the last resort.

The most common blockage is in the sink or basin trap. Solidified grease and soap form a soft plug that can be removed with a manual drain rod or a mild chemical clean if the pipe is PVC. Caustic soda should not be used on old lead or copper pipes, as it corrodes the metal and causes worse problems than the original blockage. For toilets, a good quality plunger is worth having at home. It's the first thing to try. If it doesn't work after five to ten plunges, call a plumber. Forcing it further will break the toilet's wax seal, creating an additional problem. Only when the material allows and the case requires it. We always prefer the mechanical method (rod, machine) because it doesn't damage pipes or joints.
