This is a break AND leak (two individual problems in same area) where an outside contractor installed 3" HDPE pipe through the original 4" PVC main line under a bus drive to "repair" the 4" line about 1-1/2 years ago. Didn't hold and now we're having to do it. Only problem is that I've told the boss I don't guarantee the repair because of the HDPE's propensity to creep and that one of the connections we're working on didn't have stiffeners installed per repair coupling manufacturer's requirements meaning the HDPE may no longer be true to roundness. They welded a 3" x 4" "bell" where they made the connection on the one side and just didn't leave enough 4" to work with (via Dresser or Romac coupling) if there are problems. Original contractor is coming out in the morning and welding a flange onto the end and then we'll bolt a Van Stone PVC flange onto it. We'll then be able to complete the 4" PVC reconnect. However... I still won't guarantee my work on this one. They poured a thrust block on the other side of the drive but if it's anything like we encountered today we'll still end up with excessive "rubber band" creep... coupled with the fact that a booster pump is on the system. Boss says if it fails again then we'll just go out and cut the asphalt, dig up the old pipe and re-do everything via our normal repair route which WILL hold. I'll take some pictures tomorrow of the butt fusion welding since I've never seen it done up close and personal. BTW... This is only Louie's second job using the Bobcat backhoe and he's doing one heck of a job for us. Gordon was brought out to give him OTJ training and by the end of the day was able to just totally back off. Leo, of course, is my regular partner and he really bullied me out of the hole several times today. They said I was pure white and thoroughly drenched from the 104 degree heat and made me go sit in the AC of my truck for awhile.
