Murphy's Law on broken pipe is they never occur in easy access locations. However, I think there is a fairly easy solution to you problem. I don't know how much PVC parts are available in Chile, but you can get them on line. What you need beside standard couplers, a small section of pipe, and a new tee is a slip repair coupler. You can just go to this site and get all for the information you need. http://www.dripworksusa.com/store/pvcrepair.php I have repaired several broken pipes with these couplers and they work very well.
