    None. ...just the collar transitions from the trunk to the flex duct.

    It was earlier in the posts. I have (plastic?) flex ducting connected to a duct board trunk.

    HORROR!!!

    I just pulled off the outer zip tie and the inner liner has nothing holding it on! No wonder it's leaking! I am REALLY depressed because the other 2 I checked leaked the same way and...

    Wow, that's the info I need! Thanks for that description of how to seal the flex duct!

    Alright, I went back into the attic:

    * With my laser thermometer, the temp in the attic is around 110 F (at the vertical level of the trunk).
    * The temp of the outside of the ductboard trunk is...
  7. OK, makes sense. I think the key element for me...

    OK, makes sense. I think the key element for me to understand was: the lack of a vapor barrier on the added insulation will create condensation.

    I have one more thing (I just went into the attic)...
  8. Could someone explain (please) why adding R13...

    Could someone explain (please) why adding R13 insulation will cause condensation to R4 ductboard that already doesn't have condensation. I just don't know how it can happen. I know condensation is...

    Yes, I did an image search of "ductboard" and that's exactly what I have as my trunk. So I am proposing wrapping ductboard with batt insulation.

    Other Info:
    * I'm in Central PA (super humid)
    * The system is rather new; installed about 3 years ago.

    It's a square trunk. I'll go up now to check it out and edit this post to let you know more.

    OK, It's 12x12 and it's insulated; I think it said R4 on it (the print is really bad). The ducting...
  12. Should I Insulate My Attic Ductwork for Better Cooling?

    My house's central A/C system takes about an hour to cool one degree when it's around 90 degrees outside; If I insulate the ductwork in the attic, will I get faster results?

    * I have an 1800 s.f....

    The thermostat is about 1 year old and has been working fine. I also have it set at .9.

    I found out from documentation that I can just twist off the power head and water shouldn't start shooting...

    WOW, thanks for the quick reply guys!

    So the opening of the valve is what triggers the circulating pump ...that explains it perfectly. Yes, the valve is very noisy; it probably finally failed last...

    I woke up last night at 3:30am freezing and found that the zone-valve (1 of 3) was OPEN but the circulator pump would not operate for that zone only.

    I verified that the circulator pump was OK...
