My new chimney guy was out and did a yearly inspection and found out my clean out "T" and first section of 30" pipe is split inside and white insulation is coming out when you tap on it. The split is 3" long in the "T" then goes through the seam and about 5" long in the first pipe so 8" long all together. The camera he stuck up the pipe to check it was preaty cool. He was very thorough so I think i'm going to use him for now on. He also said it looks like it was there for a year or two, all the rest looked great. He was going to do some checkin into it for me but he was real busy and didn't know how long it would take. Its a heart and cooley model (TD) type (HT) 7" Class A pipe. If anyone has heard of them or know where to get replacement parts PLEASE let me know cause there's now way i can replace 28' of insulated pipe right now. The only thing that I found is a catalog index. JD
