Got an emergency call today, 21yr old on the sticks of a 7 1/2 tonner. Digging trench for conduits for power, ground absolutely trash. Lots of volcanic floaters amongst the filthy grey waterlogged clay. Anyhow one slip trying to move a floater and bang, ripped a 20mm copper water service. Now with the new Viega thought this would be a good in out scenario but ............!!!!
Water services had been replaced and they had pushed them through the middle of the old steel pipe. Heard about this before but first time in 30+ yrs actually got to the job and gone......??????????????
Dont know how he did it but exposed enough for me to crimp off and stop flow. No idea where the ferrel was located so clled the Wate Corp. God damn got a bloke who was just fantastic. Took one look and said he would take over. Now it is not often I give up but was glad with this one.
However just wantred to put it out there and ask the question, what would you do. Copper tube is fairly neat inside the steel pipe so cutting with pipe cutter would have been too dangerous. The cutter would have pushed through and cut the copper before the steel was separated. Sorry back up a bit, had to go back along pipe approx. 500mm to cut out a crease in the steel which meant cu inside was compromised too. Also needed to get fresh copper to put freeze coupling on. What a nightmare.
Note:- whenever we open road or pavement as a contractor we need to pay permits. The Water Corporations send teams in and they dig. Oh yeah, they reckon they have one big permit(I think it is called an Excavator). They can open up whole roads without anyone blinking an eye. Stuff up traffic flow. One last real serious consideration, main gas supply running in ground close to broken pipe and pretty serious smell in ground surrounding. I was nervous of sparks.
Sorry for the long story.
