Agree with Bama. But for me the question is, am I positive that I can get all of the water completely out ???
Scenario: There is a low point in my line somewhere. I blow air through the system, but it forms an air pocket over-top of the water in that section of pipe. I think I have all of the water out, but actually I don't. The water settles back into this area when the air stops blowing, and the I could have a problem.
For me, I open the low point drains, open the faucets 1 at a time to drain that line. I then cap the low point drains, and blow air (bicycle pump) through each faucet individually. I pump antifreeze through the system, and blow the air again. The antifreeze collects in the p-traps, so that is taken care of in the process. If there is a low spot in the water lines that has not blown entirely, it will now have antifreeze in it.
Oh yeah, I setup the water heater bypass valves 1st.
I do tend to be anal.
