My question is can you re-shape a copper pipe that has been somehow turned into a oval shape and be able to solder/ use it? With poly I can just heat and re-shape... I don't deal with copper too often and when I do it's simple enough. Except for this job. I should have taken pictures I was starting a install this morning, the customer had renovated his house a few years back and had a plumber stub out a copper pipe in his back yard for future irrigation. The pipe goes under a 15' wide cement patio into the house With all the nice cement walls and rocks it's virtually impossible to get underground pipe from the back to the front with out being cost effective. So we are doing to seperate DCVA's for the front and back. Now onto the situation When we dug up the copper it was bending upwards for about 2' and then it straightened out closer to the cement patio. I cut the 2' off to get a straight line of copper pipe, however the pipe is in a oval shape. ( 1" 1/4) . I can't even get a fitting around the pipe. Further more ,The pipe is about 6" below the cement, though flush up with the cement the copper pipe is somehow kinked with an indentation roughly 20% of the pipe. Warping the rest of the piping more. I underminded about 8" before I believe it returns to a normal round shape, but to do the work under 8" of the cement would be rather hard.
