Spent a couple of hours today trying to remove a blockage which seems to have accumulated in a friends waste pipe from the kitchen sink. I began by removing the trap and then using a plumbers snake, getting it down the pipe about a couple of metres or more. Thinking I had partially shifted the obstruction I poured three or four litres of caustic soda down the pipe in the expectation that this would dissolve the supposedly dislodged gunk and drain away.
Unfortunately the blockage seems more stubborn now than previously, preventing virtually any water from draining away at all. We are going to leave it to hopefully drain away over night. I would try connecting a hose to the tap and running this directly down the pipe but this very piece of waste pipe is connected to the stand pipe of the dishwasher so if the blockage is still present any running water will simply discharge out of the top of the standpipe. Any suggestions as to what we can pursue should the blockage still persist? I have some Thaumafix Liquid Drain Rod but this is a very strong. Is it likely to have a dangerous reaction with the caustic soda already in the pipe? Any help much appreciated.
