When traveling around the country, we encounter various qualities of water as supplied by the campgrounds or fill locations where we get water. We like to ensure that the water we carry in our fresh water tank is filtered and soft and that the drinking water that we use is as pure and clean and bacteria-free as possible.
We have a water softener system on Gracie to give us filtered and soft water for household needs (showers, hand washing, clothes washing, etc.). In addition, we have an RO (reverse osmosis) system to purify the water that we use for drinking, cooking, making ice cubes, etc. Our RO system gets its water input after the water has already been through the softener.
Carl recharges the water softener monthly (every 4-5 weeks). This involves putting two 1-pound plain salt containers into the softener unit and flushing water through for about 20 minutes.
Carl replaces most of the filters on the RO system once a year (there is one filter which only needs to be replaced every five years).
We typically use more than a gallon of RO water per day for drinking and cooking. In preparation for being away from shore water (boondocking or in sites where we do not have a water hookup), before heading to the campground, when we still are on hookups, we draw off 7 gallons of RO water into a blue container (that we keep in the shower). If we know that we're going to be away from a water hookup for more than a week, we have a second 7 gallon blue container (stored in Mesa) that we can fill and carry with us. We do this when we're going to Quartzsite and plan to be there more than a week. You can imagine that it is a bit inconvenient to move a 7 gallon containers of water out and in every time we want to take a shower, so we don't keep the 7 gallon containers except when we anticipate a need. In Quartzsite, we cannot generate our own RO water (no hookups), but there are distribution stations in town, so we can take an empty container in the Jeep and fill it if needed. Note that we *can* take Gracie into town and fill our fresh water tank if we need to (and dump our grey and black tanks), but doing that kind of fill only gives us softened water. It takes longer to make RO water, so we do not produce RO water when we're just filling our water tanks and not attached to the spigot for our stay.
Our RO system has had a ~3 gallon pressurized holding tank that keeps the water in the "basement" (under the rig) as it is made so it is available to us via the refrigerator water dispenser inside Gracie without a wait. Carl had a second tank in our shed in Mesa and he decided that it would be helpful to have a second tank for times that we are boondocking - so we brought that along with us to put into the system later at an opportune time. One of the downsides to using from the blue containers is that they do not provide water via the refrigerator; this isn't a problem for water, we just pour from the blue container into a water pitcher. But the icemaker in the refrigerator only fills from the RO tank in the basement -- so we have run low or run out of ice at times when we're away from water hookups for a while.
Friday was the day to accomplish the RO system work...

Carl had both tanks out to get them ready to work together... |

The tanks both have an air bladder that serves to allow the tank to be pressurized and provide water up from the basement to the refrigerator. The bladder keeps the air and the water separate from each other. In the picture, Carl is adding air to the bladder of the tank that has not previously been in use. |

Carl had the necessary replacement filters on-hand and was replacing the yearly filters (you can see two that he has removed on the left side, and he is working on putting the filter into the second stage of the RO system). |

The system with updated filters replaced in the bay -- ready to provide another year of filtered water for us in Gracie. |
The maintenance activities on the RO system would be the same in a house-installed system; in fact, the system that we have on Gracie is the same system that Carl had installed in his townhouse before going fulltime in the RV. We feel that having a water purification system is very important in an RV where you have no idea about the quality of the water that the campground is delivering to your rig. Water softening is important as we are frequently in areas where the water is very hard.
