Is Drain Saddle Clamp on RO system an IPC violation? Plumbing

For starters I live in Mesa, AZ. I'm dealing with a plumber who isn't standing behind his work. Hopefully you can tell me if I would be in the right to report him to the ROC?

I purchased an Reverse Osmosis system from a Costco Vendor back in November 2014. The installation was done in my garage since I have a hookup for a sink that was never installed. The Drain stub is perfectly situated on the opposite side of the wall from my refrigerator so all the installer needed to do is punch the pre and post filter lines through the wall and into my Fridge. The installer then used a Drain Saddle Clamp (which i understood to be manufacturer supplied) to connect the RO waste water line to the drain stub coming out of the wall.

Last week I noticed in my kitchen 4 of my tiles had cracked and lifted from the their mortar by water. I followed water damage back through the wall and to that drain. It turned out the hole he drilled for the saddle clamp rusted shut sometime in those six months of use causing the seal to break on the saddle and the water had been trickling into my wall since.

I asked one of my friends who used to be a plumber in another state (now working for the city in a water treatment facility) what he thought. He said he didn't think that a saddle clamp was to code. He used section 310.1 of the uniform plumbing code 2012 as reference.

I called the plumber and to their credit they came out free of charge. At first his fix was to just clear the hole and put a new saddle on, however i told him that was unacceptable. I didn't want this problem to happen again in six months, so he goes out to the truck and come back with a 4 inch long plastic pipe. His plan then was to remove my metal drain stub, and replace it with this plastic pipe and then reinstall the saddle. I asked him if that was the right way to do it, as in to code. He tells me hold on, he then goes out to the truck, comes back with a series a pipes, builds a trap to the drain, attaches the trap to 2 feet of vertical pipe, then mount the drain tube from the RO to the wall with a piece of wood as a spacer about 1 inch above the vertical pipe.

After he leaves I have my plumber buddy come take a look, he tells me that this is how the other plumber should have done it the first time.

Problem I'm having now is the plumbing company wont take responsibly for the water damage to my drywall, cabinets and tiles caused by the leak. They say the problem was not in the saddle but in my preexisting pipe that rusted. However if they had done the install right the first time, that pipe wouldn't have been there, and the tiny hole the plumber drilled wouldn't have rusted shut.

I want to make sure before I file a complaint to the Arizona ROC that I do have right on my side. After doing some homework I have found the City of Mesa plumbing code follows the International Plumbing Code published in 2006 and not the Uniform Plumbing Code my buddy referenced (remember he worked as a plumber in another state). I looked through the IPC 2006 and in Chapter 7 which is titled "Sanitary Drainage", section 707.1 I found the following:

SECTION 707 PROHIBITED JOINTS AND CONNECTIONS

707.1 Prohibited joints.

The following types of joints and connections shall be prohibited:

1. Cement or concrete joints.
2. Mastic or hot-pour bituminous joints.
3. Joints made with fittings not approved for the specific installation.
4. Joints between different diameter pipes made with elastomeric rolling O-rings.
5. Solvent-cement joints between different types of plastic pipe.
6. Saddle-type fittings.

What I would like to know is does the scope of 707.1 include the waste line of an RO system? And if so can I hold my plumber to the damages?
