If you had one, I'd assume some PO installed it where it could be reached with relative ease (no sense putting one in if you still have to disassemble the cabinet to get at it). It would most likely be a brass t fitting with a tab on it to move the valve from open to bypass. You should see it very, very close to the water heater in and out flow fittings if there is one. Odds are there isn't one there. Your choice whether to put one in or not. If you are going to blow out the lines real well then you probably don't need one. Drain the water heater, drain the white water tank, open all the taps, open all the drains, blow out the lines (20psi or so), empty the tanks, close up the drains, pour some antifreeze in each sink and some in the tanks through the toilet, call it a year.
I prefer to run the antifreeze through the lines, but that's just a personal choice. I drain my white tank and black tank, then use a bypass to put antifreeze directly into the line in at the pump, pump it through the lines, pour some down each drain and directly into the black at the toilet, and call it a year. I got tired of filling the water heater so now I'm using the bypass. However, the drain for the OEM water heater on the GMC floorplan is an absolute nightmare to get at. Hopefully yours is easier.
