I use an assortment of "water" products for my RV. I have a 60 gal. fresh water holding tank. You are supposed to sanitize your holding tank once a year, I don't on this rig because I never drink water from the holding tank. I buy purified drinking water in the 16 oz bottles or fill my own jugs from a purified water source. I use Taste Pure by Camco in this tanks. I get mine at Wal Mart for less than $5.00 and this last me a very long time. This product doesn't purify the water enough to suit me. It does keep the water fresh tasting and odor free. It does have Sodium Hypochloride. I know some RV'rs that do drink from the holding tank, never connecting to the parks water. First they sanitize the tank, then refill adding the Taste Pure, then pour it through their Pur Water picture. I guess if I had to I would drink it if I knew all of this had been done.
Pur Water picture is also a product I use. A lot of the RV parks water does not taste good, and if I am not sure of their water source, I use my picture. The filters I use kill the bacteria. I think they are called 2 stage. I know they cost more than the regular filters. It says on the side panel of the box it is certified to reduce Chlorine & Chlorination by products, Heavy Metals, Sediment Micorbial Cysts, Agricultural Pollutants, Industrial Pollutants. I think they are well worth the money. I also use this water for my dog!
The other filter is a Taste Pure filter that is installed on the hose, before it goes into the RV. Some people install their at the source, but it is easier for me to put mine on the end of the hose that screws into the water line on my rig. Then when I fill my fresh water holding tank, I fill it through this filter! I have a neat "gadget" that is a long tube, screws on the hose end, and fits in my filler neck opening to my fresh water tank. This filter is less than $20.00 at Wal Mart, a lot more at RV Supply stores. Some folks keep a spray bottle of bleach water and spray the faucet before connecting their water hose. I figure my filter takes care of that, so I don't do that. I have seen dogs lifting their leg on the faucet, with the owner standing there watching!I have a stand alone ice maker, a Uline, and I want any water that comes into it to be filtered before it comes through it!
Sounds like a lot of work, but it's really not.
