Not in our field. Engineers are saddled with competive costs analysis.

Again.. Not in our field. Many times we and our customers have to demand
the extra's to make the equipment more viable.. The name of the game is
cost cutting and still make a profit..Plus the stockholders demand an
annual check.

Obvious that you are not happy with your present Service company. Check
the yellow pages or call your local building Services Inspection
department for a list of competent licensed and Bonded companies.
You might even call for a reinspection of the last fellows installation job.

Not a problem. In a divorce she will get the house with all of its leaks.

This really is not the Forum for complaints that should be handled in
your own locale.

Nope. She gets the house. HE gets the leaks.

Three responses to my question:

Do what you want! (No technical discussion.)
Local Techs are God-Like! (No technical discussion.)
Engineers are God-Like! (No technical discussion.)

Conclusion: Avoid these people.

Real answer: The dual-chamber exhaust vent pipe, part number 321147-301
is associated with Payne, Bryant, Carrier, TempStar and other furnace
manufacturers for the 90+ efficiency furnaces. With such wide usage, it
probably is in there for a good reason and should NOT be replaced with a
plain length of pipe.

Therefore, spend the considerable amount of time trying to source the $10
part from someone that will sell it to you without demanding you also pay
for a $135 service call to put it in.

For $125 (or $135), they are more than willing to come out and look at
it...

It's a really tough call: the technicians in the field see the results of
the best and worst engineering and can often make things better than the
original design. They can also make it worse.

On the other hand, the engineer who specified the dual-chamber pipe had to
convince the company bean counters that the additional 70-cent cost per
$950 furnace would not bankrupt the company, that it really was needed for
best performance. Sometimes, however, engineers overengineer.

In this instance, does it cure a problem not likely to happen, or is the
technician oblivious to any problem that doesn't instantly appear before
their eyes?

By the way, the need to replace this pipe is based on the local,
competent, licensed, insured, professionally trained HVAC technician
half-gluing up 5 chunks of PVC and unions instead of one continuoou
section and water pouring out of several of the joints and flooding the
garage floor. It has reach the point of divorce court if I do not do
something about all the leaks.

Thanks,
Dan
