I found it at my local Home Depot store.

The harder item to find is the cement (glue).  I had to go to a local Graiger commercial supply business to obtain it.

Is there anything out there that says that the indoor pipes should be insulated? My contractor is refusing to insulate the pipes because they are located in my crawlspace that is open to my basement and is making a nice swamp of condensation above my vapor barrier.

Yes, they should be insulated per IGSHPA installation standard 3A.9 and 3A.10.

Can you send me what 3A.9 and 3A.10 says, so I can get my contractor to do this?

Just because its its IGSHP code doesn't mean your contractor has to do it. Unless of course he is a member. What a busch league contractor though, did you check references?

I just checked with the IGSHPA website, and my ground loop installer is on there. The guy who did the rest of the system did an awesome job, and he recommended this loop contractor.

When I questioned the loop installer about not insulating the lines once they enter the house and run in the crawlspace they provided the following response. They offered to put my vapor barrier on top of the lines, but refused to insulate.

"The lines can sweat for a short period during the spring and again in the fall but will not sweat in the summer. They will actually get frost on them in the coldest part of the winter. It is standard practice to lay the geothermal lines on the crawl space floor. We never insulate the lines in the crawl. We have been doing it this way for 20 years."

gaurding against condensation is code. IGSHPA isn't. was the job inspected?

It was not inspected by the county or anything.

Okay then Houston, you might have a problem. No geo or for that matter any heating appliance (by and large) may be legally installed without a permit/inspection.
Before I fly off the deep end, how many contractors did you survey and what was the discussion regarding permits?
I'm not criticizing you at all, but believe it or not; some folks do not interview multiple contractors and some even ask that permits not be pulled.

I talked to 2 different contractors. They did not mention anything regarding permits. We are located out in the middle of no where. I tried to find information about code requirements, but was unable to find anything.

Call another contractor and ask him, or state licensing people. You might also ask your township/village/city hall. They'll know what building dept to call.
Both a mechanical and electrical permit are required on virtually every heat pump installation. Some people do not wish to have them. I think that's folly. I f you don't want your contractor legally on the hook to do the job right, then you accept the responsibility.
That said, since you don't already have one, make sure you don't inadvertantly open a can of worms (bring an inspector in if you have lot's of other un codeworthy issues around the house).
You might also mention to the installing contractor that a buddy told you that preventing condensation was a code issue and- oh, by the way, did you pull a permit for the installation?
Good luck,

My earth loop contractor has agreed to provide me with the pipe insulation. :-).

Imagine that ;)

If they advertise or claim IGSHPA then they should be following the specs.

Some areas's don't have permits and inspections at all.  When I built my house I had electrical permit and inspection but not a mechanical permit and inspection. 

Was there a building permit?

Every now and then while driving in really rural areas I see a road sign along the lines of "Entering Hullaballoo Township - permits required", from which I infer that the area I was in just prior does not require permits.

What I haven't seen is something like "Welcome to Buzzard's Breath - no permits needed here - build how and as you like..."

No permits required where I am building.

sorry for those of you where the fox is tasked with gaurding the coop.

If you are truly in an area where permits aren't required vs enforcement that is extremely lax, you must do 10 times the due dilligence.
Good luck with that,
