If you start with an empty fresh water tank and an empty waste tank (remember that they are not 100% empty, after being pumped out).:
* Drain the water heater, then close the drain valve.
* Add the AF to the fresh tank. Keep an eye on the AF level in the tank, add more if needed, in order to perform the steps below.
* Run the AF through each faucet (galley, head and transom ... if applicable). Run both the hot and the cold, but do one at a time. For example, run the hot until you have solid AF from the spout, then change over to the cold and do the same. Run the water that will be coming out of the faucets (before the AF gets to them) into a bucket, if you have a gray water holding tank. Then let the AF run through the drain. If your gray water goes over-board, you don't especially have to use the bucket to dispose of the water, prior to the AF coming through.
* Drain the water heater. If you do the hot water first, you can capture the drained AF from the heater and reuse it for the cold side of the system (add it back to the fresh water tank).
* While running the galley and the head, you will also be flushing the shower sump, unless your model dumps these directly overboard, in this case, you would need to dump some AF into the shower drain in order to flush it. You likely do not have a gray-water holding tank, so all of your sink and shower drains will go overboard in one way or another, If you do have a gray water tank, the AF that you've been running through the faucets will be going through the shower drain and into the tank. Pour a gallon or two into the shower drain, so that it will go into the waste tank since it won't have been fully emptied when it was pumped out.
* Pour a gallon or so into the head (toilet) to flush the head and to add the AF to the waste tank.
Note that many prefer to blow the lines out, due to the work that is required to flush the AF, in the spring.
