Is the water heater drained now?
Do you have a W/H by-pass valve set?
In the future, I'd:
1.) Open W/H drain.
2.) Blow out the lines with compressed air (helps keep the pink stuff from getting diluted with the water in the lines)
3.) Use the by-pass valves on the W/H and blow out the lines again (just to make sure...if the W/H isn't bypassed, you'll get air out the W/H drain.)
4.) Pump the pink stuff to all valves (sinks, toilet, toilet sprayer, and showers (inside and out)).
5.) Add remaining pink to the drains and toilet (to keep seal wet during the winter).
Typically, you can do a winterizing with about 2-3 gallons of A/F.
If you are not sure, I think I'd make the investment (about $6-10) and re-do the winterizing....after all, all you will have done, is add more anti-freeze to the holding tanks, and that won't hurt anything. If you did make a mistake, it could be costly, if it's not corrected:(
Good Luck:)
