You can sanitize the tank and lines with 1 cup bleach to your freshwater tank fill the tank the rest of the way with water. Turn faucets on one at a time until you smell the bleach. Let stand at LEAST 4 hours then drain. Fill the fresh water tank again with fresh water. Run each faucet until you no longer smell the bleach in each one. You are now sanitized. You should probably put the water heater in by-pass mode when you sanitize the system unless that tank is full of crud as well. Hope this helps!

Got to reading about the freshwater tank sanitation procedure described here and thought to myself it would be a good idea to do that to my tank even though I’ve never used it. So, dumb question here but, how would I go about inserting the 1 cup of bleach inside my fresh water tank so I can sanitize it?
Thanks,
