In kitchens typically appear three problems.
The sink tube (40mm diameter) filled with grease and food debris, causing obstruction after siphon tube, specifying pass inside with a rotating flexible device that thoroughly clean obstruction.
The junction between the narrow tube of the sink with the (wider) community horizontal tube is completely filled with fat compact preventing the passage of waste. You need to locate the horizontal tube, practice access to it, remove all obstructing fat by our cleaning machines, then we proceed to the control using camera-probe verifying the perfect cleaning of the tube. Finally a top-mounted record surface is reconstructed and.
The tailpiece has a negative slope at some point (ie the tube has a slight upward tilt), depositing fat and solid parts at the lowest point, causing a jam. The point of obstruction is located and repaired to avoid future problems.
