Does anyone know where I can beg, scrounge or borrow a \\\"flexible endoscope\\\" on the cheap. I have a property abroad with drainage tube for a washing machine. This will take a normal water flow but not the surge when the m/c empties. I\\\'ve tried all known mechanical & chemical unblockers to no avail. I think there may be something lodged in the pipe just around the bend. Unfortunately unlike UK properties the pipe (& U bend) is in the wall & doesn\\\'t re-appear the other side into a drain. It travels down through the wall never to be seen again. My one hope is a flexible edoscope to identify & hopefully resolve the problem. My last resort is to start knocking the wall down to get at the piping, but the problem may be some distance away. Can anyone help?????
