Hi, Just found this site when looking for some help. I have a dishwasher which has a split in its waste pipe (the grey corrugated plastic type from the dishwasher itself) The hose seems to have three sections in it and if I could remove the middle section it would remove the split. Trouble is, I cannot for the life of me figure out how to open up the hose where it seems to have joins, can anyone help me please?
