This pure eteit the pipe in the kitchen - or between AC and evacuation tubes. The pipe was completely blocked. The pipeline has four 90 degree angles but the gun eatait asses flexible, but not too flexible. We have the need to push and pull from time to time. The problem was at a distance of 4 meters from the sink (I discovered) and was canalisaton with a diameter of 40mm. Unblocking the gun was a 10mm diameter. The first time it works, but after cleaning the head and twice - the result was perfect. I am very happy. This is a good product for the price and less expensive that a plumber! I hope this comment you help and you have my apologies for mauvasie French - ju am Scottish!
