How to Fix a Burst Water Pipe with a Slip Coupling

This guide will not only save you stress, money and time, but it will also provide you with a permanent and professional fix that far outweighs the use and expense of temporary tapes and pastes for your water pipes. The fix time should take you about 10 minutes and cost around £12.


  1. 1
    Isolate the water at the mains stopcock inside the property. This is usually found under the kitchen sink.
  2. 2
    Open the taps. Open the one upstairs and the one on the ground floor if you have an upstairs property. This will enable you to fully drain residual water from the pipe work.
  3. 3
    Cut the required section out of the pipework that has burst. When cutting, ensure that you have taken out enough for the slip coupling to fit into.
  4. 4
    Compress the slip coupling. Push fit onto one end of the cut pipework.
  5. 5
    Extend the slip coupling and fit onto the opposite end of the pipework.
  6. 6
    Give a sharp and sturdy push to each end to ensure the coupling has fully seated onto the pipes.
  7. 7
    Close the taps that you opened.
  8. 8
    Turn the mains water back on. It is best to have a second person to keep an eye on the coupling whilst the pipework comes under pressure. Initially, turn the stopcock on about 1/4 of a turn, leave for 15 seconds; then, if no leaks occur, turn the stopcock on fully, then back a 1/4 of a turn.


  • Remember to go to each tap and slowly turn them on to release any trapped air. This will save people getting splashed when the air is unknowingly released!
  • It's a handy idea to keep to hand baby nappies (diapers) or incontinence sheets; they are the perfect solution for soaking up a reasonable quantity of water without using up good towels or numerous rolls of kitchen/toilet paper.
  • Always keep a slip coupling to hand; if you use one, then you will know its value and hopefully you will replace it to hold as a spare.
