How To Repair Broken Stormwater Pipes

One of the occupational hazards of doing retic and using a mechanical trencher is that we sometimes hit other pipes under the ground. Some are easier to fix than others and some require a plumber. Where we can we will fix the pipes on the spot, but it isn’t always possible.

Yesterday I accidentally cut thru a stormwater pipe thinking it was the conduit supplied for retic under a driveway. I was half way thru the cut (trimming what I thought was excess) when I realised what I had done… Oops… The pipe I wanted was further down the drive, but now I was left with the job of repairing my mistake.

Sometimes when stormwater pipe is chipped or cracked we can fix it by using another piece of stormwater, cutting it lengthways and using it a a sleeve. You slip it over, glue it and usually that’s all good.

In this case I needed to actually rejoin the two pipes – tricky when neither of them are flexible. It was a clean cut but it was all the way thru so a sleeve wasn’t going to work.

The solution?

Get a 90ml coupling, lift the most ‘movable’ piece of pipe above the other and slip the coupling over  it. Slide it right along, then realign the pipes and pull the coupling back over the other piece of pipe. When you are sure you have it lined up slide it up again and use some glue. You need to be sure not to get sand in between the pipes or they won’t slide.

If you have a whole section of pipe that needs replacing, or if it is impossible to lift the pipe up then simply use two couplings and do the same thing but insert a new piece of pipe where the damaged section was.
