To sanatize the water lines, water heater, and fresh water tank you need to use bleach. 1/4 cup to every 15 to 20 gallons of water is all that you need.
1. Open any low point drains to allow any antifreeze (some people just blow out the water lines with an air compressor) to drain from the water lines. Open the water faucets to allow the antifreeze to drain quicker.
2. Close all of the water faucets and low point drains. Mix 1/4 to 1/2 cup of regular bleach into a gallon of water. Pour the bleach water into your fresh water tank (make sure the drain on the tank is closed). Fill the fresh water tank with fresh water. While the tank is filling check to see if there is a by-pass on the water heater. The bi-pass takes the water heater out of the hot water loop. Depending on the type of by-pass you may have 1 to 3 valves to turn.
3. Turn the water pump on and open a faucet. When bleach water comes out of the faucet close that faucet and open another one. The pump will run for a while to fill the water heater. If you are not sure if you have the bi-pass "turned off", you can remove the drain plug from the water heater and see if there is water in the tank. Don't do this when the pump is running or you will give yourself a shower.
Make sure you run bleach water through all of your water lines, the toilet, shower and shower hose, kitchen sink, outside shower/hose, and out the city water line.
4. To sanitize the city water line turn the pump off, remove the strainer in the city water inlet. Behind the strainer you will see a plastic tip (it prevents back flow when using the fresh water tank). Push the tip in. The water pressure in the water lines will cause water to spray out of the city water connection.
5. Refill the fresh water tank so that the bleach water is in contact with all parts of the tank.
Let is sit for one hour or more. Drain the bleach water from the fresh water tank. Fill the fresh water tank with fresh water, then flush everything with fresh water. Repeat a second time with fresh water. If you smell bleach after flushing the tank and lines twice, pour some white vinegar into the fresh water tank and fill all of your water lines, water heater, freshwater tank.
The longer you leave the bleach water in the water system the harder it will be to get the bleach smell/taste out of the water. I let my system sit 1 to 2 hours and have never had to use vinegar. I have been doing this for 17 camping seasons and have never had a problem with my water system.
I hope this helps you sanitize your water system.
