I'm pretty sure the faucet is the ABP referenced above. I've attached a picture of where the threaded portion of the faucet connects to the 1/2 water supply pipe. The last 1/8 inch of the water supply line is flared and touches up against the threaded end of the faucet and it appears to be soldered. Note the threads of the faucet are larger in diameter than the flared end of the water supply line. Any ideas on how this connection is made?
