megawatt said:Not sure what you mean about this as slip couplings slide completely over the join between the new insert and original pipe i.e. they don't have internal stops for the pipe.there didn't appear to be enough pipe in the joint to form a good enough seal
At least you've got the water back on though so well done for that
Then what I was given wasn't a slip coupling. Never mind. Have got my water back on, that's all that matters!
