I am not a big fan of "the pink stuff." I prefer to hook a blowout plug to the fresh water inlet and blow out the water. Word of caution, use an "oiless" air compressor to prevent contamination of your water lines. Set the pressure regulator to 50 psi to prevent damage to your lines and then open one valve at a time until water is out. Don't forget outside showers!
Use about one cup of pink stuff in your drains and you are done!
