    I am installing the following free standing jetted tub:

    There is no water inlet faucet....the water comes into the tub through the jets in the side. Inspector is insisting that I install back flow prevention valves for both the hot and cold inlet. Is this a reasonable request and is there an easy way to do it?

    it is not only reasonable, but NECESSARY for ANY tub with submersible inlets. The 'minimum' protection would be check valves on the supply lines, if he would accept them., possibly with a rim mounted vacuum breaker on the supply line from the two handles to the jets. Otherwise you have to install backflow/vacuum breakers on both lines, but one would have to be suitable for hot water.
