Drain, pump the pink, then blow the pink. Leave the pink in the p-traps, (or like me, remove the p-traps under the kitchen sink and bathroom sink, but not before getting some down the holding tanks.
Make sure holding tanks are empty as possible and clean as possible. Then the pink will help lubricate the slide valves.
By-pass the water heater completely, just drain it. Put the plug or anode rod back in, but don't make it tight-tight. Leave it so it will turn very, very easy. It will rust up after 3 years. If you make it tight, it will be almost impossible to break loose. So absolutely do not snug it up. And absolutely do not leave it out. The threads on your tank will rust up making it near impossible to put a new plug in (after 3 years). So (1) bypass, (2) drain completely, (3) flush it out with a tank flusher to get all the sediment out of the bottom (4) let that drain completely, (5) re-insert the anode rod or plug, finger tight (or a little less), keep it so it turns easily both directions.
