Help with Coachmen "Water Works" panel

For those that only have a hose connection to fill the fresh tank, about the best solution is to buy and inexpensive cartridge water filter. Just connect it line with your water hose, and without a cartridge, fill the cannister with your straight bleach. then screw it back together, and fill tank as normal. Depending on your tank size, you may need to fill cannister several times to get required amount of bleach. Then keep the cannister and filter to use whenever you are connected to shore water at a campsite. Some places you need it, others may not, but doesn't hurt anything to leave in it place all the time. Just change the filter cartridge every once in a while.
