Yeah, it’s very simple when you have a filler port like that. What if you have the screw-on connection for your water filling?

Screw on a short length of hose and fill via funnel as shown. A good choice is to use the short kink preventer that may be on your external water source hose.

The video doesn’t address what to do about your in line water filters for your rig and residential fridge when adding the chlorine to your system.

Hydrogen Peroxide works just as well and is environmentally friendly.

Hydrogen Peroxide disinfects surfaces at full strength. It sounds expensive to fill a water tank with full strength hydrogen peroxide. Even a gallon of Peroxide in 30 gal of water might not do much.

Bleach has very little chlorine and lot of stuff that leaves a bad taste if you don’t fully flush (and you may need to flush again). Better is to use swimming pool chlorine at 1 teaspoon per 100 gallons. If you are going to follow with a flush, you can use the full teaspoon. If not, use a partial teaspoon that matches your tank size.

Most swimming pool chorines have a lot of additives. If you buy regular bleach, it doesn’t have additives.
