The standard way to deal with this is to install length of pipe to catch the air bubbles. Say the pipe comes up out of the floor to the level of your sink. Instead of putting an L-shaped connector and going straight to the faucet, they put in a T. One arm goes down to the supply pipe, one comes out of the wall for the sink, and one coninues up inside the wall for about a foot and is then capped off. This provides the air with a place to go and allows the recoil of flowing water abruptly shut off someplace to go.

Alas, without tearing open the walls, it's pretty hard to retrofit this to a house where a cheap-*** contractor skimped on this
