If you are going to put antifreeze in the lines, there is no need to blow them out first.
1. Put switch in the winterize ON position.
2. Put switch in the water heater bypass ON position.
3. Connect a short piece of water hose to the winterize inlet and drop the other end into a jug of antifreeze. Or pour 3-4 gallons of antifreeze in a bucket and drop the hose into that. I bought a cheap 10' fresh water hose at Walmart and cut it to about 4'.
4. Turn on the water pump.
5. Open a low point drain until you see pink stuff. Then close it.
6. Repeat with second low point drain.
7. Turn on an inside cold water faucet until you see pink stuff. Let some run to put pink stuff in trap. Turn off cold. Repeat with hot water.
8. Repeat one at a time with all other faucets.
9. Do same with toilet.
10. Do same with outside shower faucet.
11. If you have a clothes washer, follow Splendide (or whatever brand) instructions for winterizing washer.
12. Connect a short hose from your outside shower to your black tank flush inlet and run some antifreeze thru the flush lines.
13. Drain water heater and flush it out well getting all the settlement out.
14. Drain the fresh water tank.

The pump will start and stop as you open and close the faucets. Watch the antifreeze jug or bucket carefully as it will suck the antifreeze out quickly and start to suck air if you let it get low.

You can winterize by putting antifreeze in the fresh water tank, but then you have to flush that tank well to get it all out again in the spring.
