If your 2007 is anything like my 2005, and I bet it is, the vacuum breaker is behind the shower. You can access it from the left hand kitchen closet. There should be a removable panel there. If not you will have to make a hole yourself. Be sure to close the sliding door as it will block your view.



The easier way is to remove the back wall of the passthru compartment, find the lines that feed the vacuum breaker, cut each one and connect them together (using a couple of 90 degree Shark Bite connectors). This will eliminate the vacuum breaker, and the leak behind the shower. You do need to put an anti-siphon valve on the convenience center connection to provide the same back flow protection
