You will never get the tank completely empty.. Just remember to "treat" the tank twice a year... (one cup of bleach in the tank fill with water.. pump it through your system let it sit for several hours and drain... ) it also helps to drive it a bit so all of the tank gets the bleach treatment include the hot water heater when doing this but dont turn on the water heater.. drain everything then refill with fresh water through the entire system and drain that too.. then you should be ready to go...
