From what I can gather, a water bypass valve would be unnesecarry on a PRM intake. The PRM is designed to eliminate the chance of water ingestion by enclosing inside the the filter inside the intake tube, in the middle. I'm not 100% sure how it all works, but in all of their ads, they make a point of saying that there is virtually no chance of water ingestion with their intakes. If you're still nervous about water, there should be no reason why you couldn't fit a bypass valve on, it'd just be a matter of determining the diameter of your intake pipe, and cutting it in half. The valve just attaches with hose clamps and holds the two halves together.
