both the IPC and Upc code do not allow PVC within a structure.
IPC Table 605.4 and 605.5 neither lists PVC as an acceptable material.
Does IPC allow PVC for supply pipe (605.3 in my book)?

Yes, but only for service pipe. Water service pipe must terminate at or before the main water shutoff valve, located where the water service pipe enters the structure. In this case, since the tank and equipment are within the garage and the garage is defined as a structure, you can not use PVC.

Bob, let me clarify the post a bit. some might think that you could say run the PVC across the basement and then put a valve on and go from there. But another code says that there must be a full port, full open shutoff valve located as close to the entry point and before the water meter. If the OP is really concerned though, the smart thing would be to make a phone call to the building dept and ask the inspector what he will and will not accept. You would hate to install everything only to have to tear it out and start over. Ultimately it comes down to the inspectors discretion.
You can actually pipe PVC from the well to the structure. Note I said structure. Yes, things get a little gray here and depend a lot on the inspectors interpretation. I/E, would a well house be a structure? So though well systems are different the interpretation of the code should not be.
A quick search found this and a quick read seems to disagree with your understanding, or statement. There is not one word about manufactures setting the standard or any other standards. The government does that and CERTIFIES that the manufactures' products comply; (from the nsf.org web site).Why yes, indeed I do know it carries NSF cert. along with ASTM cert. Both certifications, certify that the pipe is manufactured to the standards supplied by the manufacturer. Neither NSF nor ASTM actually set those standards, they are set by the manufacturer and the testing agencies make sure that the products meet such standards.
It can also be used above ground, at least to the shut off valve you mention.Continuing on, The IPC and the UPC and every other plumbing code I have on in my vast library all allow PVC sch 40 pipe and fittings to be used for potable water supply piping that is not within the structure served. In other words it can be used underground.
I certainly did not, nor did anyone else mention plumbing their house with PVC.Not withstanding Mr. Slussers post above, I can assure you that if you plumb your homes water distribution with PVC it will not pass inspection, so please consult with your local inspector before beginning any plumbing project.
This is awkward, but...
