Fresh water tank on board
The sanitize ratio is 1/4 cup bleach per 15 gal. capacity.
I hook up my FW hose to RV fill connection, pour the amount of bleach I need into the hose and then connect to my water source and fill tank. Also, run faucets so lines will be sanitized. Let stand for 12-24 hours. Drain, fill and flush twice.
I usually do this in the spring and early fall. If we do not use RV for several months then I sanitize.
