Blow out winterizing question

I take pump out and put in house, cap pump line, bypass and drain water heater, drain fresh tank, blow out all lines, dump about 2c antifreeze in each drain, another gallon down toilet (to keep valve o-ring lubed), and leave it for the winter. 20 years in Chicagoland winters - no problem. The first year I used the antifreeze and tasted it for months. Will never do that again. Don't forget to blow out "hidden" lines that you can forget about - Washer line, outside showers, main drain lines under camper (if you have them). Also, close all valves when done. This keeps the system "sealed" and prevents condensation from building up which CAN pool and then freeze.
