My current setup is a straight hose from the head to the holding tank. From there I can pump over board or pump out. Between the head and the holding tank (very close to the head) I want to add a y valve so it can go overboard or to the tank. It's easy enough to plumb but was wondering how you prevent the water from pushing back into the head while running? Is a vent loop up 2ft off the y enough or do I have to use a check valve or something else? Thanks

When the Y valve is in the holding tank position, it's closing off the direct overboard discharge avenue, so you won't have any water coming in that way. Just flop it back to the holding tank position when you're done or steaming in, pretty straight forward, no need for a vented loop.

My concern is my crew leaving it on the overboard and filling my cabin with water.
