How to get your water system pure for spring use again

First, ensure your water storage system is clean. It's a multi-step process, but not difficult. Locate the drain valve for your rig's fresh water tank. It's a small plastic valve, connected to the fresh water tank by a plastic tube or line. Usually you'll find it mounted on the siding outside the rig; in some rigs it could be in a basement storage area. Once located, open the valve or valves you may have 2, completely drain the tank, and then close the valve. If you have a water filter disconnect it replace with water bypass line.

Next, you'll mix up a batch of household bleach and water. In a clean bucket add unscented household bleach in this proportion: One-quarter cup bleach for every 15 gallons of fresh water tank capacity. Now pour this solution via a clean funnel into your RV fresh water tank.

Next, top off the tank with fresh water. It's best to agitate the solution, so hitch up the rig and drive around a few blocks, generously sloshing the water in the tank. Next, turn on the rig's fresh water pump. Open and run each water fixture in the RV, from toilet to shower, sink to outside shower. Run them until you smell the bleach solution, then shut them off. Allow the solution to stand in the water lines and tank for several hours, preferably overnight. Be sure to turn off the RV water pump.

Next, drain the fresh water tank, and then close the drain valve. Refill with clean water run all fixtures wide open for 3-5 mins and then shut off pump go outside drain tank from drain valve youíll now add to the tank apple cider vinegar, in the amount of 1 quart for each 5 gallons of tank capacity. Top off the tank with fresh water agitate the solution again by the old "once around the block," trick. Now run the fixtures again, this time sniffing for vinegar. Allow to stand for a few hours, then drain the tank, and refill with fresh water. Be sure to run all the fixtures clear of the cider solution. Now you can replace the old water filter with a new one or reuse the old one. With your tanks pure, clean, and sweetened up, be sure to keep them that way by doing this every 8 weeks.
